All of the sudden the printer did something weird. Despite being homed, docked properly, when I started a print from Octoprint the head started to shake wanting to dock again, then moved to the centre, did not home and started to print in mid air. For completeness, the head was homed, then docked and then I moved the bed down from the LCD. Then a print was sent via octoprint with the following starting code ;BigBox Printer Start Script Begin ;Homing M117 Homing. ;G28 ;G29 ;set extruders offset M218 T1 X37.7 Y0 ;dock T0 G1 X70 Y200 F3000 G1 X70 Y235 F3000 M117 Print Starting. ;BigBox Printer Start Script End what could be that goes wrong? I have removed now the dock from the start script, but have not tried again.
