Just want to throw this out before for people’s attention before it gets really bad if what I suspect is true… tagging @bar…
Firmware V1.27 incorporates changes to the kinematics routine to use chain elongation and sled weight and ignores chain sag compensation values. This requires recalibration… see this thread:
Worse, though, is that Ground Control v1.27 calibration routine still uses the old kinematics. Therefore, it is possible that someone may not even be able to calibrate the machine correctly because the results don’t resolve into a solution… see this thread:
I think v1.27 firmware should be pulled for the time being.
