Hello,
I've built a 30x40 CNC loosley based on CNC Router Parts unit. I'm running nema 23 motors running an x and slaved a axis with ball screws.
Running Mach3 and a g540 driver.
The bottom line is...if I run a quickie little program to cycle the x axis back and forth about ten times, the two sides are no longer aligned with each other.
The X axis is no longer aligned with the A axis so therefore the gantry becomes skewed. I've check to make sure the settings in Mach are the same for each axis and
checked all the electrical connections. Mechanically, as far as I can tell, nothing is binding on either side.
I'm at a loss to further diagnose the problem as I feel I've tried everything I could think of.
Is it possible the motors are not "exactly" the same?? Hard to believe....
Any suggestions would be greatly appreciated.
Thanks
Art
