Re: Problem keeping my gantry square

>So any ideas with this problem of mine?

Just a shot in the dark... if you have two X axis
screws, if the leads are not exactly the same, but
the motors are doing the same (correct) thing, you
will get some racking. Some variation between
supposedly identical leadscrews is to be expected
(thats why I've been pushing Art to have a calibration/
leadscrew compensation for each screw, in a dual axis
screw application such as an XXYZ gantry.

Even worse, one may be 5 threads/inch, the other
might be 5 threads/25 mm.
