I am experiencing a racking problem on the Y axis gantry and looking for some ideas on how to correct this problem. I am new to the blog (my first post) and assume this is a common problem which has been previously addressed. Thus, sorry if I am kicking a dead horse.
Specifically, what I would like to do is have 2 stepper motors, each driving lead screws on either sides of the gantry. Also I would like to have 2 homing switches such that when running a homing routine the gantry is squared to the X axis in the process. I know Mach3 has a “slave” feature for such stepper configurations but not sure how this works or how to wire the motors and limit switches.
As background, the router has a table size of 24” square. The hardware consists of Probotix boards (PBX-RF breakout, 3 Probostep VX drivers) and unipolar steppers.
Thanks in advance for your help.
