Bottom Line UP Front: Z-Axis is randomly going opposite direction during jogging. Jugetek Motor (different from X/Y motors)
Assembled and tested Pro XXL over the past few days. Using caution because I am a zero hour newbie. I did some dry runs and then ran with the sharpie and a simple text file (similar to Hello World). Then I went with the MC Etcher and was successful on a test and small aluminum plate.
Today, first initialization and I got the Homing Fail error. Checked as much as I could and read what I could find. Notable here: Z Axis was noisy.
Now, ran some jobs on pine with the spindle going. No problems (other than my learning curve). Performance was flawless. Attempted to jog and stepper is making clunk sound and randomly going opposite direction. When commanded up, sometimes up, sometimes down…and vice versa. I don’t even know where to start beyond searching here. Since it has been working with fine tolerances and this is not the initial start-up…I am lost.
BTW - Super stoked that this is here, assembled, making chips, and it has far exceeded my expectations in design and accuracy. I took a few build notes that I’ll put up later.
