Re: [CAD_CAM_EDM_DRO] Re: Problem keeping my gantry square, using a dual drive slaved set-up with Ge cko's.

I have two racks and two motors.

Looks like I might have fixed the problem, 'touch wood'. I re run the
wires going to the motors, and it has been okay. Might have been a bit of
'noise'.

I will send you a pic tomorrow, as I do not have a picture of the motors
since I made a belt reduction for them.
