I am having a very difficult times with the depth of my Z-axis. I tried everything. I calibrated it, checked the set screws, checked to see if the lead screw is bent(it isn’t). One very odd thing is when I set the jog to 1 inch and press it, the spindle will keep going down until it hits the board, then I have to hit the E Stop button.
Hey Ian, it might be a wiring issue or the stepper amount is off. Would you mind reaching out directly to support (email@example.com) and we can get it fixed!
