Please view our development log [http://openfarmtech.org/index.php?title=XYZ here.] The specifications development for a robust and scaleable machine is under development [http://openfarmtech.org/index.php?title=XYZ_Table here]. The prototype specifications for a torch table application will be developed on this page.
 
The basic design follows.
 
Using ball screws and linear bearings appears to be the easiest method. Present research indicates that profile guide rails are twice as cheap for the accuracy required, so this will be redesigned.

Compare this to [http://www.torchmate.com/industrial/index.htm gear drive and linear rails], which appears to be more complicated in terms of drive components.
 
=Torch Table Implementation=
 
Specifications:
*.01 inch accuracy
*Precision acme rod
*Profile rail guides
Motors: [http://www.xylotex.com/StepperMotor.htm]
*Nema 23 Double Stack/Double Shaft Bipolar Stepper Motor, Flats ground on each end
*269 inch lb holding torque on main axis
*Rated Current - 2.8A/phase
*Shaft width - .25 inch
Controller:
*
 
*Direct coupling to precision acme rod
 
=Bill of Materials for a Simple Prototype=
 
It appears that the Xylotex drive is applicable to large torch tables. [http://www.kickassmachinesinc.com/ Here is one] that Xylotex told me uses their controllers and motors.
