So far I’ve assembled my machine and connected with my laptop.
I had limit switch error that I corrected, two connections reversed.
Now the Z axis moved up, then it went down the X axis, though not as smoothly as I think it should. It got to the end and then the Y motors start to spin but it won’t move. It gets very shaky/jittery and I have to power it off.
I tried having very tight tension on the Y belts as well as backing off the tension but that doesn’t seem to help, it just jitters differently.
I’ve gone back and double checked connections with the wire harnesses and on the control board and I don’t see anything else wrong there.
The Y motors do turn but it just seems locked in place.
Check the set screws that fasten the pulleys to the stepper motor shafts. On each, there should be two set screws, one should be over the flat part of the stepper motor shaft, and both should be tight.
Second, if X and Z move correctly but the machine shakes/jitters in place on the Y axis, it could be that the two Y motor connections are reversed, and the left and right motor fight each other. Double-check cabling to the controller for the two Y motor cables ? It also possible that they were mislabeled: try swapping the two Y motor cables at the controller, see if it changes anything.
Well, after a day off from work and a clear head I went out and figured out the problem in about 2 minutes. I had skipped removing the bolts holding the gantry in place. I didn’t get directions with my unit and was going by a pdf on my phone. I guess somewhere in the scrolling I missed it.
I also had a limit switch that was installed ever so slightly high but that was an easy fix to lower.
It does successfully initialize. Now to try a test cut and see how that goes.
