Hey all,

I am in the process of designing my first plasma table setup. My system will be an overhead gantry design similar to torch mate3 setup.

Table size will be 4x8 and intend to use linear bearings and rack and pinion on the x and y axis using roughly a 2:1 gear ratio. the Gantry will be made of extruded alumimum to keep the overall mass to a minimum. The y-axis will use 2 motors in parallel for optimal torque.

Electroincs will be stepper @ about 50vdc wired in bi-polar parallel and g202's running them

my problem is sizing of the steppers. I realize there are a lot of different factors but would 2- 260oz/in motors be sufficent to propell the y-axis.

here are the motors I plan on using : http://www.homeshopcnc.com/page3.html

Any suggestions or opinions would be apprieated

thanks
