Apply babysteps to one or more axes using current units. Offsets applied with [`M290`](/docs/gcode/M290.html) 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, [`M290`](/docs/gcode/M290.html) also modifies the Probe Z Offset (with no immediate effects). The new Z offset applies to successive probing operations, and can be saved with [`M500`](/docs/gcode/M500.html). 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.
