Why is my machine suddenly poking holes below the cut depth as it finishes the design?
Ensure your Z axis is calibrated properly, your Z probing is established properly, and you’re material depth is set correctly.
Can you point me to an area I can read about calibrating the z axis? Another issue is it keeps carving deeper and deeper as it goes along.
Check the set screw on the Z axis pulley.
V-bit protruding too deep, causing the dog bone effect.
Is either mechanical or V-bit related (flat tip or minor true angle variation vs stated)
Yes exactly.
Update. With the help of Julie from Inventables I was able to fix this issue by readjusting (pulling back) the z axis motor. So happy to up and running again!!
