1/2" to 1/4" - Rigid Coupling (Plastic/Delrin)

Would you be able to provide .DWG/.DXF files instead of .NC files for the CNC Routing Machine Kit Version 1.3 please?

These files are no longer available. We suggest purchasing a kit, like the blackToe, or blackFoot as these kits are far more rigid and perform much better. https://www.buildyourcnc.com/blackToe2x4v40.aspx https://www.buildyourcnc.com/Item/cnc-machine-blackFoot-v4 Additional Information: 20 Additional Information:

wiring for the spindle / inverter

Will the 40W CO2 laser etch glass?

CO2 lasers can (40w included) can mark glass, but it is not actually etching the glass. When a CO2 laser's focal lasing energy is at the surface, or just past the surface of glass, the air inside that portion of the glass will expand and cause a tiny crack. This gives the appearance of etched glass, but not with the same fineness of etching from, say, sand blasting or acid etching (with hexafluorosilicic acid). If the laser "etching" of the glass is not to the fineness that you desire, you can laser cut the adhesive material used in the acid etching process as an alternative. You also need to consider the glass you are using. I have learned that not all glass is created equal. Some glass will work well for this (dollar store glass we have tested and works well), and some will not. I believe that lasing tempered glass will probably give some interesting results. Additional Information:

Will the 40W CO2 laser cut through clear and color acrylic?

Yes, from our test with clear and opaque acrylic, the CO2 laser can cut fully through.

where can i found the tutorial to install and connect the 40 W laser to the greenbull cnc

To install the 40 Watt laser on the greenBull, provided that you have the proper mount, go to the following page: https://buildyourcnc.com/item/cnc-machine-laser-spindle-combo-head The mount can be purchased on this page as well.

When will the #40 Collar/Sprocket Combo be available ?

We are in the process of finding a replacement vendor. If you purchase the combo, we will ship it out as soon as we have them in stock. If you change your mind, or we do not find a suitable vendor, you will be able to get a refund.

When we simulate cutting a part, the part is 40% larger than it should be. Why?

What software are you using to simulate the CAM machining operations? Additional Information: I drew my part in ViaCad, opened part in CamBam to produce GCode, then Mach3 to simulate cutting part. Everything worked as it should but part was too large. Additional Information: It sounds like steps per unit is not calibrated properly. Use the Mach3 to calibrate the axes. In the settings tab, there will be axis calibration labeled just above the reset button. There is a button just just below axis calibration called set steps per unit. When the button is clicked, mach3 will present you with a dialog box asking for a measurement of how far to move the specific axis you need to calibrate (use a number that will not make the machine over run the axis). The machine will move to a certain length. Measure that length and enter it into the next dialog box that Mach3 presents to you. Do this for each axis.

What�s the size and weight of the blacktooth shipping box?

For our blackTooth laser cuter and engraver, the specified packages in shipment may vary to option chosen and additional purchases. 3 packages: 40" x 21" x 5"/54 lb. 17" x 12" x 12"/27 lb. 40" x 10" x 7"/5 lb.

What warranty is there on the 40W laser and power supply?

Most of our products have a warranty that extends for 1 year; however, there are parts like end mills and laser tubes which are considered consumables. These parts, when used, become worn, or the usable life is decreased. Laser tubes are parts that, when used, shorten its life, and especially when proper methods are not used (i.e. running the tube with water), can drastically reduce the life of the tube. Therefore, the warranty for laser tubes are 30 days if the laser tube was not used.

WHAT THICKNESS OF MATERIAL CAN THE BLACKTOOTH LASER CUT?

A standard 40W CO2 laser will cut up to 1/4" thick of material, be it wood, acrylic, card stock, leather, fabric, foam, cork, etc. (Decent speed and final cut are heavily dependent on a strong air assist upgrade) Metals cannot be cut due to the power level and wavelength of the CO2 laser. But it can be marked with special solutions like Cermark or Thermark.

What size/ kind of rail is the hiwin rail that you sell?

My apologies for not having the specifications on the product page for our Hiwin rail and block: The specifications are as follows (we will add this information to the product page): Rail: Rail width: 20mm Mounting bolt: M5x16 Mounting hole center to hole center: 60mm Guide Block: Width of block: 63mm Length of block:77.5mm Mounting holes distance in the width direction: 53mm Mounting holes distance in the length direction: 40mm Both: From bottom of rail to top of block: 30mm From block bottom to bottom of rail (clearance): 4.6mm

What size breaker is required for the 2.2kw 220v vfd ?

Since a 220V 2.2kW, or 2200W spindle will consume 9 to 10 amps at full torque: 2200W/220V = 10A 2200W/240V = 9.2A then a 15 amp breaker would be suitable for this load. Additional Information:

What materials can the laser cut?

Our 40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc. Speed and final cut are greatly enhanced by an air assist upgrade. We also offer an 80W laser which has approximately twice the capabilities of the 40W.

What materials can the Greenbull machine cut? What materials can the laser cut? Can the laser etch?

The Greenbull machine can cut a very wide variety of materials ranging from foam to aluminum. We recommend the use of our 2.2kW spindle to allow the greatest flexibility. Aside from that, the most important thing is to use an appropriate end mill for the material you are cutting and to use appropriate speeds and feed rates. BYCNC Response: Our 40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc. Speed and final cut are greatly enhanced by an air assist upgrade. We also offer an 80W laser which has approximately twice the capabilities of the 40W. Additional Information:

what is the current draw of the 220v VFD

The current draw of the 220V VFD is 10 amps. Since the spindle is rated at 2.2kW, and the mains for the US 220V is in the range of 220V to 240V, 2200W/220V = 10A 2200W/240V = 9.167A So, the rage of current draw will be between 10A and 9A, but it is advisable to provide a buffer of about 5 more amps if possible.

What is the bill of materials included in the build your own laser 2' x 4' 40 watt

The general bill of materials for the blackTooth 24"x20" laser system is as follows: - The structural components (MDO and Plastic parts) - The hardware to assemble all of the structural and mechanical parts - Mechanical parts like v-groove bearings, bearings for shafts, shafts, pulleys, belts, etc. - All of the motion electronics like motors, drivers, and laser controller - Wire to connect all of the electronics - All of the laser components including the laser tube, mirrors, mirror mounts, nozzle and lens - Pneumatic components including the air pump and tubing - Hydraulic components to cool the laser tube including a water pump and tubing blackTooth 24"x20" Laser

WHAT IS KERF?

Kerf is the cutting width from the lasers beam. This will change in width depending on your power level, higher power will increase your kerf width. This is usually around 0.15mm for a 40w laser using a 2" lens

What is a clear indication of a failing/failed laser tube? I know that laser tubes eventually "wear out", but how does one determine if the tube is loosing its "oomph"? My 40W Blacktooth laser tube return goes through an ammeter, so is the ammeter reading proportional to the beam strength, or can the beam die and still draw the same amount of current?

Dealing with glass co2 laser tubes, it is difficult to accurately tell if it is going out or loosing "oomph". The laser will loose its co2 levels, which will cause it to loose cutting strength. We have noticed that the laser at its "strongest" or new state fires a purplish/reddish color laser through the tube, and when it is loosing its cutting strength it turns to a faded red orange/orange color. Using a ammeter will only measure the current going to the tube. The PSU will not know when the tube is losing its cutting strength, so it will constantly flow the same voltage and current. Additional Information: Additional Information: Additional Information: How many dots should come out of the laser Additional Information: Additional Information: Additional Information:

What engraver do you have to put a logo on anodized aluminum and that is a desktop that can be transported to events?

We have two relatively small machines that can be transported to events. One is a laser engraving and cutting machine called the blackTooth. You can find this machine here: https://www.buildyourcnc.com/item/cnc-machine-blacktooth-laser-cutter-engraver-40w The blackTooth can engrave into enodized aluminum very well. The engraved (lased) portion of the anodized aluminum will turn white. The other is a CNC machine canned the blueChick. The blueChick CNC Router can be found here: https://www.buildyourcnc.com/blueChickVersion42CNCMachineKit.aspx The CNC router can engrave with a special engraving bit and can cut/engrave into most metals (anodized or not). Hope this helps.

WHAT ARE THE SPINDLE INVERTERS (VFD) INPUT AC CONNECTIONS FROM WALL OUTLET?

Input to VFD: 240V Active - R 240V Neutral - S Ground - E Additional Information:

The laser adapter for the greenBull can host laser tubes more powerful than 80W?

The laser mount for the greenBull is designed and suited for a 40W tube only. The 80W tube is too large to mount on the gantry.

So the only way to get one of your machines is to buy it already cut, and/or assembled? I can't cut one on my existing machine?

That is correct, the only manner to get our machines is to buy one of our kits. We do not provide or sell our plans, the only CNC machine you can find on our website will be the scratch build kit and plans which is a 20' x 40' , (https://buildyourcnc.com/Documents/CNC%20Kit%201-1.pdf).

parallel break out board is not working-relay keeps switching my computer off when I power up

Do you have anything connected to the relay? Additional Information: is the relay controlled by a pinout on the BoB? Additional Information: Nothing is attached to the relay pins I am only using 2 and 3 and 5v for x driver and led indicator, 4 and 5 and 5v for y driver and led indicator, and 6 to fire the laser and the led indicator. I am also using a 5v out for the laser power control circuit and one pin of the 5k pot. Ground is shared on the laser power supply, the cnc power supply and the x and y driver. I am using the computer motherboard supplied by Buildyoucnc running ubuntu 12.04.5 LTS and linuxcnc. Bios is set to use ECP, I have tried normal and I have tried EPP, all with the same results. If I plug in the parallel after the computer starts up it doesn't switch but I can't control either axis motors Additional Information: Laser is currently not connected for safety reasons Additional Information: I am using the parallel BoB for the 40 watt C02 Laser Cutter and Engraver(blacktooth), with the supplied integrated computer running Ubuntu 12.04.5 LTS and linuxcnc. Right now, when I have the parallel header connected to the BoB(as well as usb power supplied by the computer) and I start the computer, I am able to see the first splash screen of text indicating that the computer is starting up, then the relay on the BoB switches, turning the computer off and then back on again. This happens over and over again and the computer cannot fully start into the linux os. If I unplug the parallel cable from the BoB, I can start the computer, sign in and then plug the BoB back in without it shutting down the computer. Can anyone explain why this happens? I should also say that I cannot talk to the steppers in stepconfig of linuxcnc, I get to the test this motor section and nothing happens when I try to jog either the x or y motors. In the y config, I actually triggered the relay and sent the machine back into the start up failure loop I mentioned in the beginning. Additional Information: Fixed this problem, the parallel cable was not seated well, found some screws to make a strong connection, now that part is working. Unfortunately, the stepconfig in linuxcnc is still not talking to the motor drivers and the setup for determining steps for inch in the build instructions is nothing like the set up in linuxcnc. In the instructions it says motor steps per revolution*microsteps/pulley pitch per tooth*number of teeth and in this case the recommended input would be (200*16)/.08*20 teeth = 2000 steps per inch the formula in linuxcnc is very different

on the laser cutter and engraver, can it do steel and how thick

The laser engraver can cut steel to a depth of 1/4" (one quarter inch). Additional Information: Additional Information: However, the CO2 laser cutters at 40 watts cannot cut steel.

My build looks like black toe, used chain #25 and your idler sprockets, but small holes are not round

If possible, will you be able to take pictures of the holes that our not round, and send them to customerservice@buildyourcnc.com. Furthermore is this CNC build a machine of ours? If it is not our blackToe 2' x 4' it may be one of our blueChick's 1' x 3' (https://buildyourcnc.com/blueChickVersion42CNCMachineKit.aspx), or blackFoot's 4' x 8'(https://buildyourcnc.com/blackFoot48v40.aspx).

Is there any way to bring the cost of https://www.buildyourcnc.com/item/cnc-machine-blacktooth-laser-cutter-engraver-40w down if I only need the hardware and components, not the body? I have a cnc waterjet and could cut these parts if dimensions were provided.

We can lower the price for just the hardware and also for the structure. However we do not have any files, dimensions, for public access. Additional Information: Would there be any/enough measurement or info on the instructions to extrapolate the dimensions? What would the new pricing be?

Is there any warranty on the 40w laser tube?

For most of our products the warranty is 30 days.

Is the blackToe better than the plans, book, 20" x 40" machine

The blackToe machine is better than the plans machine and this is why: the blackToe machine prevents racking since it has chains on both sides of the gantry; the chain drive provides higher rapid velocity becuase of the mechanical ratio; the chains can be tensioned, so the machine has less backlash overall; the overall structure is much stiffer due to the design of the gantry box form; the structure and mechanics is more compact due to the v-groove bearings having a smaller form than the bearing and bearing truck assembly; the blackToe can receive many more types of routers since the mounts clamp to the outside housing of the router/spindle motor.

I would like to build a low cost laser engraver/ cutter, can your 40w laser power supply be controlled with an arduino or is it only controlled by the controller sold here?

You can control our 40W laser power supply (which controls the laser tube) with an Arduino, if that is your intention. The trigger for turning the laser on and off uses a 5V level. To control intensity, you can use the Arduino PWM output. If you want the Arduino to move the machine as well (providing pulse trains to each of the stepper motor drivers) then you will need to make sure you consider the processing speed of the Arduino so you will be able to run the stepper motors at the speed you need for the laser engraving/cutting. Our laser controller do all of these functions. Here is a link to our laser control system: https://www.buildyourcnc.com/item/Laser-Component-Laser-Control-System Additional Information: Thank you! I am building a 3 axis cnc/ engraver and I think this would be a good option as well as the router head and the 3d printing head. How heavy is the tube? I may mount it directly onto one of the axis of the machine to eliminate the need to line up all three axis, similar to what you have with your xl engraver. Additional Information: The tube isn't that heavy, but when filled with water, it can get up to a few pounds. The key is to use the axis moving the nozzle for engraving as this requires fast back and forth motion. The cutting is generally dependent on the axes moving from vector to vector at a relatively slow motion, so this is not a problem.

I would like to add laser option to my cnc mill. Is this possible?

It will be very soon. We are developing a mount for a 40W laser tube for the blackToe, blackFoot and greenBull. This will be available within 2 months.

I wonder if it is possible to do 3d engraving with the 40w laser kit? different depths is the same piece of wood.

You can cut at varying depths with the 40w laser cutting and engraving machine. Each layer of engraving with the laser will leave behind a black charred film that will reduce the effectiveness of the engraving for deeper layers; therefore, a very strong air assist will be needed to blow this film off of the surface of the material. CNC machines are more successful and efficient at carving and should be considered.

I was wondering what the max depth is for something to go into the 40W C02 Laser cutter and engraver with blacktooth

Hello, I was wondering if the Blactooth laser cutter can engrave in 3d, different depths in the same piece of wood? Additional Information:

I purchased a 3040 CNC router off eBay a year ago and would like to change the controls. The steppers are 185oz.in motors. My question do i need to purchase a interface board and break out boards?

When dealing with 3rd party machines, we have a universal setup that will fit almost any other machine, although please take in consideration the specifications in which your stepper motors and drivers are used and set to! Now changing the controls, would be more or less changing the Breakout board/interface board to a different one that might use a different program to run your machine. Usually you will not need to change your interface board or breakout board, unless the 3rd party manufacture made it specifically to that set up.

I originally bought 4 Sainsmart ST4045-A1 Drivers. One failed. Can I replace the defective one with one of yours? Or should I replace all 4? I have bought your NEMA24's and BOBs. Learned my lesson. Newbie mistake, I admit. Thanks.

If you already have our motors and interface controller, it would be best to run all motors with our drivers. You would not be compelled to replace all of the drivers, but it may be advisable for future issues.

I live in China and my company would like to buy the 40w laser cutting machine. I am wondering if you can help us assemble and maintain the machine in China? Do you have any service point here? Thank you

Currently our only location is in Katy, Texas at this current time, we can help you assemble the machine and if any issues occur we can always help you with the problems, but will have to be managed through email or phone (which ever is your preference).

I just wanted to know what I can expect to pay to build the blackFoot 4'x8' CNC machine, excluding computer, software and router? Is the kit complete or do I have to purchase additional items to finish?

You will need to build the table unit for your machine. There are instructions on how to do this at the bottom of the product page here, https://www.buildyourcnc.com/Item/cnc-machine-blackFoot-v4 There is no estimate on how much this will cost though, since there are too many variables involved to do this. - PC with parallel port and USB port - 20awg stranded wires for the motors - http://www.buildyourcnc.com/electronicscombo.aspx - 18awg stranded wires for power supply to drivers - 24awg stranded wires for breakout board to drivers (location and spacing of components varies from one person to another, so we do not provide cables/wires) - General purpose extension cord (cut the female end off) to provide power to power supply - USB cable to power breakout board - Parallel cable to communicate to breakout board - Router - (optional - instead of router) Spindle with power inverter http://www.buildyourcnc.com/SpindlesAndAccessories.aspx - (if purchasing spindle with inverter) General purpose extension cord (240v) (cut the female end off) to provide power to power inverter - End Mill(s) http://www.buildyourcnc.com/ProductsEndMills.aspx - CAD, and/or CAD-CAM software (to produce geometry, machine operations, and g-code) http://www.buildyourcnc.com/CNCsoftware.aspx - CNC control software (to read g-code and control machine) http://www.buildyourcnc.com/CNCsoftware.aspx This answer is applicable to most of our machines with the exception of the greenLean and the blueChick since those machines are equipped with a table structure.

I have been asked to provide an exhaust for the Blacktooth Laser Cutter CO2 40W. I see no specifications or guidelines for exhausting fumes from the machine. Can someone help me?

Exhausting the blackTooth laser cutter is a very important consideration and should be taken seriously, especially if you are cutting materials that give off toxic fumes when the material is burned. You will want a 4 inch hose to connect from the blackTooth to a blower, and another 4 inch hose to connect from the blower to the outside. The blower should be sufficient to provide completely negative pressure within the laser enclosure so there will be no escape of gasses. The connections at the machine, at the blower and at the location the hose exhausts outside should be thoroughly checked for leaks. Use a gasket, or silicone. Once complete, try cutting a non-toxic material that will give off an odor (wood, or non-toxic plastic) and try the system and determine if the smell is present. Additional Information: Additional Information: Additional Information:

I have a KL-4030 stepper motor driver that I only have about an hour use on it but seems to be bad already. Has anyone out there had the same problem?

The KL-4030 is a Keling 3.0 amp stepper motor driver. These are generally pretty robust drivers. You mentioned in the question that it worked for one hour. This sounds like it could be a contact issue with the wiring in the terminals. I would recommend that you check all of the connections. The terminals that are used in these drivers have terminals that are easily used incorrectly. Make sure to open the terminal all the way using a small screw driver. Then insert the exposed wire into the opening and re-tighten the terminal. Make sure of a good connection by tugging on the wires. Also, check kthe digital wires that connect from the driver to the control board.

I bought your book and was hopeing it had plans or dimentions on how to build a cnc to hold a 4x8 sheet of ply. Will the CNC in the book scale up? Limit switches for axis. The print shows that you can wire the limits either n.o. or n.c. so if this is correct I would need to tell the board in the software how to look at these limits, I'm either going to get an input or loose an input depend on how i wire it.

BYCNC Response: The book build was intended to be 20 inches x 40 inches. Larger machines were designed after the book build was introduced so customers would have the option to go bigger than what the book offered. Check out our larger machines on the website as the machines sizes range from 1 foot x 3 feet all the way up to 6 feet x 12+ feet. User Response: I'm not wanting to spend $3,000+ on a machine, I want to build one that will do a 4x8 sheet of wood. Will the plans in the book scale up? BYCNC Response: It is possible to scale the book build up, but the rigidity of the gantry would be questionable at that span, even if the height of the gantry structure were to be increased. The gantry design would need to be modified to become a box shape rather than a flat configuration. The kits on the site were design for those wanting a larger machine.

I am using clear Avery labels through a laser printer then coated with car Clear Coat to label 18 gauge galvanized 1.75" x 4" steel plates. Will a 40 Watt CO2 laser mark Galvanized steel?

There is a spray called Cermark (also in tape form) that allows CO2 laser marking on various metals. We have tried this on many metals, but not galvanized, so I don't know how well this would work.

I am planning to buy cutter engraver. How much power needed to cut .5" baltic birch plywood?

Our CO2 laser cutters and engravers can cut birch plywood. Our 40 W lasers can cut birch plywood's at about a quarter inch. You will need a laser at least 80 W of power to cut that thickness of birch plywood. Our vertical laser XL would be able to handle that material. CO2 lasers in general are not the best candidate for cutting thick woods. For thick materials, it is best to use a CNC router.

I am looking to set up a long table, 4 x 12 foot I would need to cut wood of modest density less than 1 inch thick, and I would also need to bevel some of the cuts, so I think this is a four axis unit. Which of your kits plus upgrades would make sense? I am very capable of assembly of a bunch of boxes full of parts.

Dealing with a 4' x 12' machine, our blackFoot kit will be your best option. Since our machines are only limited to the width but not length wise, you can add however much extra rail and roller chain to accommodate your extended length. Now adding our 4th axis kit (https://www.buildyourcnc.com/item/axes-4th) will be needed for your 4th axis (unless custom design is required). These items will be the best requirements to build a 4' x 12' 4th axis machine. Machine (either parallel/USB BoB): https://www.buildyourcnc.com/blackFoot48v40.aspx 4th axis: https://www.buildyourcnc.com/item/axes-4th

I am looking at buying the blacktooth-laser-cutter-engraver-40w. Can you give me some idea of the types and thickness of material this machine will cut and/or ingrave?

Considering that "materials being lased by may emit gasses that are harmful to humans (corrode human tissue and cause damage to respiratory organs). Always read the MSDS (Material Safety Data Sheet) for the material to be lased. You can find these MSDS from manufacturer websites for the material you are considering for use in the laser system." We successfully have worked on Thin sheets of Brasswood, glass, foam, plexi-glass. The thickest materials you will be able to successfully cut is 1/4".

I am interested in getting your 40W laser system. How difficult will it be to increase the size to 48" x 48"?

The blackTooth machine, as it is designed cannot be modified easily as the box within which it is contained also serve as its structure. We are currently designing a special mount for the greenBull (for the 40 watt tube) which will provide 5'x10' or 6'x12' work area and the machine is far less expensive than comparable 4'x8' laser systems. We are also developing a 4'x8' 80 watt system where the tube is in the horizontal orientation. More information can be found in the R&D section.

I am building the 24" x 48" machine from the original book and i was wondering if anyone can provide me with the actual cutting area possible with that machine.

The cutting area is 20" x 40" for the book machine. This area is determined by the 2'x4' sheets that make up the bed of the machine. You can increase this area if you use larger sheets and adjust the gantry width by the same difference of the width of the sheets. You can also use the plans from Woodsmith magazine to build a larger machine. https://www.woodsmith.com/article/build-a-cnc-router-for-your-own-shop/ Additional Information: need cutting area of 25 x 49 what size of gantry Additional Information: need cutting area of 25 x 49 what size of gantry

I am building my own laser and have watch your trocen videos.....but laser wont fire...double checked wiring and all seems correct to diagram....but the kit i bought was for a 40 watt and i amd using a 60 watt power supply and tube.....What size does the power switching unit need to be ....I think mine is too small for the trigger mA

Is there a test button on the laser tube power supply? You can test the laser output by using the test button. This will help you determine if the laser tube is bad, or if you have wiring issues. Sometimes, wiring to he TL may not work as some controllers are set to active low, so you may need to wire the controller to TH instead. Additional Information: Additionally, the mA on the high tension line does not have any relationship to the digital trigger signal from the controller to the power supply.

I already built a 4 x 8ft carving machine, I would like to modify for laser cutting wood. Do you sell a conversion kit? I use Mach3 software and steppers. Thanks Ray

We offer a laser/spindle Z-axis attachment for our 4x8 greenBull CNC. The blackFoot 4x8 does not have a large enough gantry to accommodate the 40W laser tube. Additional Information: Additional Information: We do sell the parts to convert your CNC milling machine to a laser, but you will need to develop the mounts that will hold all of the laser parts to the machine, if the machine was design and built by you. We can offer guidance for this conversion. The laser parts can be found here: https://www.buildyourcnc.com/LaserComponents.aspx

How much is your ; blackTooth Laser Cutter and Engraver CO2 40W

You can find all of the information including the price on the blackTooth Laser cutter and engraver page found here: https://www.buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx

How many hours are required top build the 40 watt kit?

Assembling any of our machines will vary from customer to customer as it is a measure of the ability of the assembler. For the blackTooth laser machines, you should be able to have it assembled between two to four well focused days.

How long is the typical build time for one of our machines.

The greenBull machine has a sturdier gantry than the blackFoot, so you can be more aggressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce your arcade cabinets. I would highly recommend getting the spindle for cutting strength and easier cleanup, if you have 240v available.

How fast can I cut 1/4" wood with the 40 watt CO2 laser?

CO2 laser will not cut wood material fast at all. This is just the nature of the laser energy. The wood is a very low absorbent of the laser energy and you will need to run probably around 10 ipm to cut through the wood. CNC is much more efficient for cutting and laser as more efficient at marking or slowly cutting if you need the small kerf. You will also need a relatively high output air source to cut efficiently. The air will blow away the char (carbon) on the wood. The black char will absorb most of the laser energy not allowing the wood to be cut well. We use a compressor for the air source, but you can use a commercial hydroponic air pump instead.

How can i calculate how much can carry my stepper motor? i have these informations: (Detent Torque: 2.2N.cm; Rotor Inertia: 54g.cm2; Holding Torque: 40N.cm). It's a nema 17

The holding torque will provide the best information for the calculation on how much your stepper motor will carry. But first, when you say carry, do you mean how much weight it can lift, how much inertia it can withstand during an acceleration and deceleration state or how fast it can accelerate or velocity it can maintain under load from the milling process?

hi. I'm in the UK. can u supply a 220-240v spindle

Yes, we can supply 220-240 volt spindles. https://buildyourcnc.com/SpindlesAndAccessories.aspx Additional Information: Additional Information: Additional Information:

Hello, I'm interested in GreenBull 5'x10' CNC machine kit with 40W laser head. Is it possible to receive an offer for this size cnc machine kit with all the mechanics, electronics and laser parts, but without all the wooden parts? We would like to build this kind of laser cutter machine with metal frame and parts. And is it possible also to get 3D drawing for machine? Waiting for your answer.

We do offer all of the parts; but it is best to purchase them a la carte. You will probably not want the hardware since this would not conform to a design in metal. All of the mechanical parts are available here: https://buildyourcnc.com/CNCMachineMechanicalParts.aspx All of the electronics you would need is available here: https://buildyourcnc.com/electronicscombo.aspx All of the laser components are available here: https://buildyourcnc.com/LaserComponents.aspx And the spindles and VFDs are available here: https://buildyourcnc.com/SpindlesAndAccessories.aspx Additional Information: Additional Information: Additional Information: Additional Information: Additional Information: Additional Information:

From your assembly instructions, it appears your table top is 3/4 thick. I planned to use a thicker table at 1 1/2 thick. I realize I will need longer bolts to attach the x-axis guide rails, but will the y-z gantry adjust for a table that thick? I am building a BlackFoot.

I apologize but the gantry legs will only be able to accommodate 3/4" thick table top (gantry sides to be specific(https://buildyourcnc.com/blackFoot48v40.aspx#prettyPhoto/28/)).This is due to the available adjust ability on the gantry legs between the v-groove bearings that ride on the top X-axis rails, and the ones that tighten on the lower rails. The Y-axis (width of the table) will have no problem with the table top being thicker, but the X-axis rail screws and gantry legs will not accommodate the 1"- 1/2" table top.

Do you sell only the laser components in a kit form?

We can sell the laser parts in a kit form. What specific parts are you looking for specifically. A typical parts list would be as follows: - 1 Laser Tube (40w or 80w) - 1 Laser Power Supply (40w or 80w) - 2 Laser Mirror Mounts - 3 Laser Mirrors - 1 Laser Mirror Mount/Lens Holder/Nozzle - 1 Lens (Focal Lengths of 1.5", 2", 2.5" or 3" depending on your application) - Laser Protective Goggles Other parts that would be optional: - Laser Controller with Control Panel - Water Chiller if using the 80w (can also be used for 40w) - Screw Terminal with Post (for laser tube connection convenience) - 5K Potentiometer if the laser controller is not included Let me know if this list matches what you would expect and I will create some kits.

Do I have to use the Postep Driver with the Pokey57CNC usb/ethernet board. Can I use the Motor Driver (24-40 volts DC, up to 3.0 amps, microstepping from 1 to 1/64) With The Pokeycnc USB/Ethernet board.

Since the Pokey57CNC outputs standard pulse and direction signals, you can use any stepper driver. So, you do not need to use the Postep driver to operate your stepper motors. The Pokey57CNC control board is extremely feature rich and can be use to control very complex light or heavy CNC systems. Since most CNC system use high current drivers, the Pokey57CNC can be used with these systems.

Can you send the 40W cutter kit to Switzerland

Absolutely. Please send an email to sales@buildyourcnc.com with your address and we will get a shipping quote for you.

The rigid aluminum 1/2" to 1/4" couplings sold here work better to couple a 1/2" shaft or lead screw to a 1/4" shaft. I would suggest using that coupling rather than the Delrin version. Here is a link to the aluminum rigid coupling: https://buildyourcnc.com/item/coupling-rigid-aluminum-!25-!5
