General Mach Discussion / Electrically preloaded Dual motor drive for Rack & Pinion
« on: May 22, 2014, 09:18:38 AM »
Hi all,
i'm researching building a 4' x 8' cnc router for a woodshop.
I was wondering if Mach3 has the capability to drive 2 stepper motors per side of X axis ( 2 pinions per rack for reduced backlash, electrically preloaded ).
That would be 4 motors for the X axis.
Motor A would drive in one direction while motor B would have less torque (dragging) to keep the pinion engaged.
When switching direction, the motors would switch also to B driving and A preloading.
Thanks,
Radu
