As the title states please give us an option to disable stepper motors… the fact that this option isn’t available is ridiculous.
It would make life so much easier if quickly moving the axis by hand if needed.
I haven’t used my printer in a while and homing my printer after changing the filament thinking it may unlock the steppers I had forgot the nozzle has to cool down before homing the z axis so once the extruder had moved to the centre of the bed area I went to change the nozzle only to find the z axis then started to lower itself, I managed to quickly fit the new nozzle however it then hit the bed slightly to hard and let a nozzle shaped dent in the centre of my bed which is now going to effect my offset…
This and other issues because of this like simply wiping down the rails etc could be made so much quicker and easier if we simply had disable stepper motor option.
Since it is steppers (position is determined by counting the number of steps instead of “scales”), if you do that, you would have to re-home once you re-enabled since they system wouldn’t have a clue where it was after you manually moved it.
Yes i understood that at the time but its just a pain in the back side to do, I would much rather just press a deactivate steppers icon… Creality have implemented this really well I cant understand why Bambu haven’t, its such a simple and more convenient addition.
You’re supposed to have the printer powered down (and cooled off) to change a nozzle. Allegedly it can damage the electronics otherwise. And… maybe it can damage us too.
It has nothing to do with grounding. You need to understand that a stepper motor is a generator when powered externally aka moving the bed back and forth manually. If you move this bed fast enough it can generate enough electricity to damage the control board.
