Talked to Precision Plasma about the carriages. They said it's either the eccentric bearing adjustment or the carriage is out of square. I said I suspected the carriage and they suggested "percussive adjustment" with a vice and rubber mallet.

Instead of working on that, I wired the motors on the X-axis and gave it a try. Seemed to work okay. But, I'm assuming that the DRO reads in the units you set (I set inches). I must have done my calculation of steps per inch wrong because I was getting two inches of movement for every inch on the DRO. I'll have to redo the calculations and see if I can figure out what went wrong.

I was adjusting the direction of movement for the X-axis by changed the active hi/low of the direction signal. I accidently changed X and Y instead of X and A. It's pretty dramatic when the steppers go in opposite directions.

I'm curious if anyone has suggestions on maximum speed and acceleration rate...........
