Started running a large 3D carving the other day and when about 3/4 of the way through the system locked up stating limits had been exceeded. I had run the “check size” function before I kicked off the project and all as good. I had re-homed and restarted the project. It proceeded to almost the exact same spot and stopped again but this time when I tried to re-go e the z axis dove deep into the material and into the bed! Ugh! Once I got the bit out and system re-homed again I started the project yet a third time. This time I noticed the 3D viewer location and actual tool were no where near in synch. I stopped and went to the work zero and the tool was off by about 3 inches in the Y axis from the original work zero. How can the work zero coordinates be lost? Why did the tool stop in almost the same position two times and then dig deep into the material when trying to re-home? The system has worked flawlessly since I assembled and got running about two weeks ago.
