  3949. - `MMURES` - Reset MMU
  3950. - `RESET` - (Careful!)
  3951. - `fv` - ?
  3952. - `M28`
  3953. - `SN`
  3954. - `Fir` - Prints firmware version
  3955. - `Rev`- Prints filament size, elelectronics, nozzle type
  3956. - `Lang` - Reset the language
  3957. - `Lz`
  3958. - `FR` - Full factory reset
  3959. - `nozzle set <diameter>` - set nozzle diameter (farm mode only), e.g. `PRUSA nozzle set 0.4`
  3960. - `nozzle D<diameter>` - check the nozzle diameter (farm mode only), works like M862.1 P, e.g. `PRUSA nozzle D0.4`

  4591. This G-code is used to calibrate the temperature drift of the PINDA (inductive Sensor).
  4592. The PINDAv2 sensor has a built-in thermistor which has the advantage that the calibration can be done once for all materials.
  4593. The Original i3 Prusa MK2/s uses PINDAv1 and this calibration improves the temperature drift, but not as good as the PINDAv2.
  4594. superPINDA sensor has internal temperature compensation and no thermistor output. There is no point of doing temperature calibration in such case.
  4595. If PINDA_THERMISTOR and SUPERPINDA_SUPPORT is defined during compilation, calibration is skipped with serial message "No PINDA thermistor".
  4596. This can be caused also if PINDA thermistor connection is broken or PINDA temperature is lower than PINDA_MINTEMP.

  4832. Default 3x3 grid can be changed on MK2.5/s and MK3/s to 7x7 grid.
  4833. #### Usage
  4834. G80 [ N | R | V | L | R | F | B ]
  4835. #### Parameters
  4836. - `N` - Number of mesh points on x axis. Default is 3. Valid values are 3 and 7.
  4837. - `R` - Probe retries. Default 3 max. 10
  4838. - `V` - Verbosity level 1=low, 10=mid, 20=high. It only can be used if the firmware has been compiled with SUPPORT_VERBOSITY active.
  4839. Using the following parameters enables additional "manual" bed leveling correction. Valid values are -100 microns to 100 microns.
  4840. #### Additional Parameters
  4841. - `L` - Left Bed Level correct value in um.
  4842. - `R` - Right Bed Level correct value in um.
  4843. - `F` - Front Bed Level correct value in um.

  8096. - An emergency crash dump includes register data, but will cause the printer to reset after the dump
  8097. is completed.
