Apply babysteps to one or more axes using current units. Offsets applied with
aren’t added to the current coordinates, but are intended for making small adjustments, especially in the Z axis, at the start of a print.
Note that when BABYSTEP_ZPROBE_OFFSET is enabled,
also modifies the Probe Z Offset (with no immediate effects). The new Z offset applies to successive probing operations, and can be saved with
. This behavior is means to coincide with the LCD Menu replacing “Z Babystepping” with “Babystep Z Probe Offset.” To avoid this side-effect, use M290 P0 or leave BABYSTEP_ZPROBE_OFFSET disabled.
Requires BABYSTEP_XY for babystepping on the XY axes.
M290 [P<bool>] [S<pos>] [X<pos>] [Y<pos>] [Z<pos>]
Use P0 to leave the Probe Z Offset unaffected. (Requires BABYSTEP_ZPROBE_OFFSET)
Alias for Z
A distance on the X axis
A distance on the Y axis
A distance on the Z axis
Babystep the Z axis by 0.25mm (in mm units mode)
M290 Z0.25 ; move up 0.25mm on the Z axis
