@Thinkersbluff — This definitely still needs testing, and another round of comparison with the community firmware to make sure we have all the important boxes ticked.

Presumably there is no need for `ENABLE_AXIS_E0` before a move, because the stepper ISR should automatically enable the E axis as needed. If that isn't happening and this won't work...

I've merged the latest code into this and cleaned up extra calls to `ENABLE_AXIS_E0`. Now it's just waiting on the refinements discussed above to handle bad conditions safely and to...

> It works thanks, this pr adds important function for mmu operation If you force it to fail by withholding the filament from the feeder, or by withholding the filament...

Probably better today … ?

Please test the [`bugfix-2.0.x` branch](https://github.com/MarlinFirmware/Marlin/archive/bugfix-2.0.x.zip) to see where it stands. If the problem has been resolved then we can close this issue. If the issue isn't resolved yet, then we...

See any issues here? ```cpp #if ENABLED(SPINDLE_CONTROL_M106_M107) case 106: M3_M4(false); break; // M106: Turn ON Laser | Spindle (clockwise), set Power | Speed case 107: M5(); break; // M107: Turn...

Essentially, this makes `M106` / `M107` into aliases for `M3` / `M5` and it doesn't require much more explanation. One caveat is that it modifies the parameters to `M106` /...

I have added a comment about the driver default changing, also in the sanity-check error message. But, is the `*_MAX_CURRENT` really the same thing as `*_CURRENT`? Correct or not, the...

More details are needed. Please log information using `M420` after each adjustment, before and after saving to EEPROM, after reboot, etc. Of course, make sure you are actually using `BABYSTEP_ZPROBE_OFFSET`...
