warning: position tolerance exceeded, But only in one direction
-
My CNC machine has 2 motors on the X axis, they are 1HCL boards.
Board 51 keeps giving me " warning: position tolerance exceeded" by the dozens. But only when traveling in the positive direction. This happens at pretty much every speedI tried:
- setting acceleration verry low
- reduced the amount of microsteps
- played with dozens of feedrates
The machine seems to work great besides spamming my console with warnings.
Board 50 never gave me a warning, even at ludicrous speeds. And it doesn't happen in the negative direction.I am out of ideas. Does anyone have any suggestions?
