I have a Commarker B4 fiber laser. I am trying to use the chuck rotary. Xtool says that the steps per rotation are 128 steps. This only produces a small movement in the rotary when I click test. I have found different recommended steps per rotation. None of them will produce a full rotation when I click test in the rotary setup. The gear on the stepper motor is smaller than the one on the chuck, so it would require a higher number of steps to produce a full rotation. I have contacted Xtool, and get their automated support reply. I’ve looked in the forum and none of the numbers work. I hope you can help.
