Dock calibration
After installing the newest firmware update I have installed different diameter Nextruders (0.4mm) I've run the calibration, during the execution of the dock calibration of Tool1, when I execute step 12, i.e. tighten the upper screw and push CONTINUE the printer LCD screen jumps one step back, one step forward and then ends in the menu of Dock calibration a red cross is displayed meaning that the dock for tool1 has not been calibrated. The same fault repeats everytime I try to perform that dock calibration. Restarted the printer twice, still the same, even when the dock cal is aborted and started all over again the same happens.. I've skipped dock cal and went on with further cals - no issues, only the dock calibration.
Is it the newest firmware bug?
