[QUOTE=Biggermens]Is the Pacific Scientific K31HXLJ-LXK-NS-00 a good stepper for a Gantry Style CNC wood router about 9 feet long 5 feet wide and the Z axe 12" tall ???
I am using a acme screw 1/2 inch with 8 turns per inch
What are the motors specs. What Axis are you wanting to drive.. All?...
I assume your 1/2 inch Acme is for the y and/or Z... If not you may consider at least 1 inch or above for the X axis drive.
The size of the motor depends a lots on your setup. Ball screws, Linear bearings and the cutting you will be doing. For a large router I would think you'll need at least 800 oz.in for the X & Y and smaller for the Z.
