I had a similar experience with the BTT Eddy:
- With a fixed z-offset, the homing value would become unstable and jump up to 0.2 mm.
- BTT mentions this behavior a bit unclearly here.
- The “beta macros” seem to be an improvement but still not to my liking.
Finally, I reverted the BTT Eddy mod and went back to the MicroProbe on this printer.
