Changing Z-Offset is not moving the Z-Axis #26

Closed tfaz099 closed 3 years ago

tfaz099 commented 3 years ago

Bug Description

After performing a complete manual leveling, then a mesh level with the "level" menu item, storing and committing changes to eeprom, running the z-offset tool, and locking in the z-offset.

Reboot to start clean and confirm Z value is correct. the nozzle grinds into the bed. Re Home Move Z to 0 select Z Offset and start turning dial.... Z Does not move.
Try clicking to "set z" ... Z still does not move

Re-Run z offset tool... z offset moves fine when turning dial.

Need z to move without clicking to commit when print is in progress.

My Configurations

Using the existing Smith Binary for 4.2.2 BL Touch (Slow)

usually it meant incorrect wiring. check ur bltouch wiring sequence, and reseat your bltouch wiring.

I think the resulting code / option change is : //#define AUTO_BED_LEVELING_BILINEAR //comment out

define AUTO_BED_LEVELING_UBL //uncomment supposedly this allows for active Z-Axis move live without having to re-home. I will test soon.

***Update - this setting was not the one that activated the active movement for the Z, and using it turns off the level menu on the unit.

The "always use babysteps" was commented out, works fine now.
