NEMA 42 Stepper Motor (1586 oz-in 3/4" single shaft) 5.5 Amps

What are the overall dimensions of the 2.5A small stepper drivers? Is there a CAD model available?

The overall dimensions of our 2.5 modular stepper divers is: L: 1.875"/ 47.625mm W: 1.433"/ 36.3982mm H: .585"/ 14.859mm (height might change due to different terminal block height (other we have on hand is .464"/ 11.7856mm)) Currently we do not have a CAD model on hand.

What are some good ways to control the vertical laser from a Linux machine?

There really isn't any good way to use Linux when using a traditional Laser Controller. If LaserCAD worked under the Linux OS, then that would work. Would you like to know an alternative to use Linux using maybe LinuxCNC? There are ways to do it, but you will find yourself deep in g-code and out of the box wiring configurations, most likely. Alternatively, you can create a dual boot scenario and put Window on the other part of the hard drive. This way, you would be able to run LaserCAD. You can also "attempt" to use LaserCAD in the wine environment, but I have a feeling that will probably not work. Additional Information: We're a small family-owned electronics and hardware manufacturer, using LinuxCNC already for milling. Dual-boot into Windows isn't a sensible option -- it would greatly reduce the utility of the machine. I have more information about our use case in https://buildyourcnc.com/FAQ/13985. Additional Information: Ok, fair enough. Then let's get into the details on how you can use LinuxCNC to operate a Laser machine. Do you have an idea what controller you will be using? Parallel? Additional Information: My first inclination was to use LinuCNC with the parallel interface board. Of that's the answer, then we might want to just add to the LinuxCNC discussion that's starting to firm up at https://buildyourcnc.com/FAQ/13985 rather than duplicate the information here. I'm open to other alternatives and am happy to hack; we make PCBs and cable harnesses as a business, so that's not a limitation either. One answer might be to use one of the open source controllers that are starting to show up. Additional Information: My turn for phone typos. ;-) I meant to say "If that's the answer, then..." Additional Information: I've started a forum topic about this at http://www.buildyourtools.com/phpBB3/viewtopic.php?f=9&t=8412&start=0 Additional Information: Good idea. Thanks. When a direct solution is realized on buildyourtools, I will post it here.

Greenbull 6x (6'x12') table dimensions

For the 6'x12' greenBull table dimensions, the table width for the greenBull table must be 80.078" (6.67' or 203.398 cm) and must overhang the underside structure by 1-1/2" to make room for the rails and this overhang portion should be 3/4" thick. The length can be variable, but remember that the gantry takes up some of that space, so add about 34 inches to make room of the gantry and the connecting hardware for the roller chain on the four corners. We recommend if you want a full 12 feet of travel, the table must be at least 178 inches.

What is the operating voltage?

The upper voltage is the voltage that the motor driver can handle. The higher the voltage, the higher the top speed you will achieve for the motor as a higher voltage reduces the time constant for current to pass through the coils. A 48-volt power supply will be fine for this motor.
