[MK3S+] Z Axis Steppers stay on and get warm when the printer is on idle. (I know this is done on purpose but I still want them to turn off!)
Hi,
I prototype a lot and actually never switch of the MK3, it's almost like a paper printer that just does the job right away when you klick print.
I know Prusa keeps the z axis steppers on to keep them under torque. I still don't really understand why they do it. When I power of the printer and power it back on all it does to calibrate is the bed leveling that's done before every print. There is no re calibration of the z axis or anything else and when the printer is turned of the z axis stays perfectly in place...
1. So, why do they need to keep the steppers powered?
2. Can I anyhow workaround this behavior and have them turned off after a print is finished?

G code is the answer.
Z axis: M18 Z E
All axis: M18

thx, I think I already tried M84 which didn't do anything and it was supposed to be the same as M18.

I'll give M18 a try right away.

The gcode commands M18 and M84 don't do anything. The z steppers are still warm a few hours after executing it.

I haven't personally checked, but according to this, it seems that for Prusa, timeout parameter must be defined for M84 to work.

M18 S10
The steppers are still warm after a few hours. :/

I think the MK3 uses the M84 command not M18. Did you try the M84 S?? format

Have you thought about chatting with support?

how about M112 or M410, perhaps a bit too drastic. Or with M84 try specifying the Z stepper explicitly, apparently without S parameter.
Does anybody know what the first parameter does?

i wondered about that, too.
After thinking about it for a long time, my own explanation would be:
If you touch the extruder (cold pull, clean nozzle...) there is the risk that the left and/or right z-stepper are moved and the x-axis movements are no longer parallel to the bed.
