I’ve looked through the topics here but I have not found anything that is exactly what I’m doing. I have had issues with repeating patterns - namely cutting stars on a flag union. My initial problem was that the stars did not come out to be the same size. So I figured that the board is slightly warped and that my clamps were not holding the material down well enough. I made new clamps. Then I found out that my hold-down screws were too long and were actually raising the waster board. I have resurfaced the waste board, found the correct length screws, and now use six clamps to hold the piece down.
Here’s the issue finally - I set zero (all) in the lower left per normal. I will manually jog back to the center to check my Z-zero again. If it is off a bit I might reset Z only. This is where I think there is a problem. When I have done this my Z gets messed up (too low) and I have ruined more that a few boards now. Is there a bug that will not allow to zero the Z axis anywhere but where Z and Y are set?
I have a bit setter but I do not have a Zero probe.
