What's the maximum speed at I can machining reliefs without lost steps with BlueChick?

This will depend on the material, end mill that you are using, and whether you are using a spindle or a router. The stepping motors and the mechanics on the blueChick (and the other machines as well) can move the machine very fast (x and y about 700 ipm rapids). You will need to refer to the manufacturer specifications for the speed on the end mill with the particular material. The Onsrud end mills sold here are of top quality and can generally go faster than standard end mills. If the reliefs are in wood, you will be able to machine around 200 to 80 ipm depending on the wood and the depth per pass. Generally, you want to rough out most of the wood with a roughing end mill then finish off with a finishing end mill with a small tip and a small step over. If you are using a router, the speeds will be slower than a spindle since the spindle can handle more torque and the torque is compensated with the VFD (Variable Frequency Drive).

Is the 4kv spindle constructed using two or four bearings?

We are posing that question with the supplier. The information will be provided shortly. Additional Information: The 4.0 kW spindle has 4 bearings. Tow of them are 7005C and the other two are 7003C

I'm interested in buying your blacktooth laser engraver for cutting out inlays on woodworking projects. I am new to laser engraving/cutting, and CAD. What is the simplest beginning software setup available to allow me to cut 2D shapes and letters for inlay work?

With our blackTooth kit, if you were to go with our lowest cost machine being $1700. With the parallel breakout board the best new beginner programs you can use, would be Mach 3 and ArtCAM, since it is a good program for beginning users. Now if you feel a little comfortable with CAD/CAM, I would recommend CAMBAM and is a good overall software since it has a large design screen which allows you to view your design more clearly. Additional Information: Additional Information: I want to avoid the Parallel Port option and go with USB. In that case, is Planet-CNC Software, and ArtCAM the best combination? Does Planet-CNC do the same thing as Mach 3 only with different physical ports?

I have your breakout board with relay parallel port , how can I wire up a regular router to that board so I can control the router

Here is how to connect your router to the parallel breakout board through the on-board relay. You will need a spare extension cord. You will need to remove a portion of the outer jacket of the extension cord to expose the white, black and green wires (white = neutral, black = live and green = ground), understanding that the neutral and live create the completed circuit. See this image of a similar connection. The terminal has the same connections. https://www.buildyourcnc.com/images/vacuum-pressure-controller-relay-terminals-700.JPG Image of the relay terminal: https://www.buildyourcnc.com/images/breakoutboardrelayNONC.PNG The live/black wire would be cut and one end of the cut would be secured into the P terminal and the other cut end would be secured into the S terminal. The live and ground wire would be uncut and travel from the plug to the router. Additional Information: You can also connect other high powered devices to the breakout board using any of the output terminals. You will need to supply extra relays like the one shown here: https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V Or you can find SSRs (Solid State Relays) that will accept 5v to drive the relay coil. Make sure the SSR will protect the 5V line from Back EMF as there is a coil in the relay. The one we sell contains a fly-back diode to protect the 5v terminal.
