Z-Axis gets deeper on repeat cuts

I created a new Project in Easel Pro using an XCarve machine that is about 4 months old.

I had to cut 20 of these changing the name on the top for each new cut.

I noticed that with each new cut, where I used the Previous location for Work Home, the Z-axis cut deeper each time. Only by a small amount, but after 3 cuts I had to reset the Z location manually before cutting another.

What can I do to resolve this?

You may want to look at the Calibration for the Z axis steps per mm setting and adjust it if need be. Check out my reply in this thread. Also, check to make sure the connection between the motor shaft and coupling is tight.

I will check the physical connection. That seems to be a more plausible reason for the downward drift of the Z-axis.


If your cnc is not configured to lock the steppers than the z axis will slowly lower under gravity combined with the vibration of the router running.
