- Start a print
- Let print finish or abort it
- Start a calibration test (menu -> advanced settings -> nozzle offsets -> measure automatically)
Running a calibration after a print can lead to disastrous results. If I complete (or cancel) a print, doing a follow up calibration has always led to bad results, whether it's just being far off center of the cube or missing the cube entirely. If it completes the calibration (with bad results) and I do a second calibration, it continues to do a bad calibration.
Power cycling the printer and then doing a calibration seems to be the only way to get a good calibration, then repeating the calibration test will repeat good results. It's only after starting a print job then running calibration that will lead to undesired results.
My conclusion is that some value(s) is changed after a print that affects the calibration test.
