@dannym I experienced a z axis malfunction twice yesterday. I ran a file that I’ve run about 6 times before, so it’s been tested, and about 3 minutes into the program the machine thought the Z axis was about 2 inches lower than it really was. I stopped the program and used the remote control to manually move the Z and it would not rise higher than a certain spot which was far lower than the real Z limit.
I reset the drives, rehomed the machine and ran the program again and it malfunctioned at the same spot 3 minutes in. This time it stalled out 3 inches lower than the real Z limit.
I’ve run this program plenty of times before and have no idea why it’s having this issue. I thought perhaps my bit was getting dull which caused friction when the machine pulled upward, but when it happened again at the same spot I wasn’t so sure.
The image below is the second time it malfunctioned. I couldn’t get the Z to go any higher than that point.
