Prusa firmware-specific G-code commands

Last updated a month ago
This article is also available in following languages: 
ENCSPLESDEITFR

This is a list of currently implemented G-Codes in Prusa firmware for i3 series printers. The description is only for Prusa Research-specific G-codes. The rest can be found on RepRap Wiki. With exception of M117, they are all shown in order of appearance in the code. That is why some G Codes aren't in numerical order.

For G-code documentation of Original Prusa Buddy firmware (MINI/+/XL/MK4), visit the Buddy firmware-specific G-code commands article.

Special internal commands

These are used by internal functions to process certain actions in the right order. Some of these are also usable by the user. They are processed early as the commands are complex (strings). These are only available on the MK3(S) as these require TMC2130 drivers:

  • CRASH DETECTED
  • CRASH RECOVER
  • CRASH_CANCEL
  • TMC_SET_WAVE
  • TMC_SET_STEP
  • TMC_SET_CHOP

M0, M1 - Stop the printer M0: Stop or Unconditional stop

Usage

M0 [P<ms<] [S<sec>] [string] M1 [P<ms>] [S<sec>] [string]

Parameters

  • P<ms>
    - Expire time, in milliseconds
  • S<sec>
    - Expire time, in seconds
  • string
    - Must for M1 and optional for M0 message to display on the LCD

G Codes

G0, G1 - Coordinated movement X Y Z E G0 & G1: Move

G2, G3 - Controlled Arc Move G2 & G3: Controlled Arc Move

These commands don't propperly work with MBL enabled. The compensation only happens at the end of the move, so avoid long arcs.

Usage

G2 [ X | Y | I | E | F ] (Clockwise Arc) 
G3 [ X | Y | I | E | F ] (Counter-Clockwise Arc)

Parameters

  • X
    - The position to move to on the X-axis

M207

G11 - Retract recover G11: Unretract

Unretracts/recovers filament according to settings of

M208

G21 - Sets Units to Millimters G21: Set Units to Millimeters

Units are in millimeters. Prusa doesn't support inches.

G28 - Home all Axes one at a time G28: Move to Origin (Home)

Using

G28
without any parameters will perform homing of all axes AND mesh bed leveling, while
G28 W
will just home all axes (no mesh bed leveling).

Usage

 G28 [ X | Y | Z | W | C ]

Parameters

  • X
    - Flag to go back to the X axis origin
  • Y
    - Flag to go back to the Y axis origin
  • Z
    - Flag to go back to the Z axis origin
  • W
    - Suppress mesh bed leveling if
    X
    ,
    Y
    or
    Z
    are not provided
  • C
    - Calibrate X and Y origin (home) - Only on MK3/s

G28 issued without parameters homes the MMU as well (invalidates the homing flags of Selector and Idler and these will perform homing async once it is considered safe, i.e. no filament in the selector)

  • P: just invalidate the selector's homing validity flag
  • I: just invalidate the idler's homing validity flag

G29 - Detailed Z-Probe G29: Detailed Z-Probe

In Prusa i3 Firmware this G-code is deactivated by default, must be turned on in the source code.

See

G81

G30 - Single Z Probe G30: Single Z-Probe

In Prusa Firmware this G-code is deactivated by default, must be turned on in the source code.

G31 - Dock the sled G31: Dock Z Probe sled

In Prusa Firmware this G-code is deactivated by default, must be turned on in the source code.

G32 - Undock the sled G32: Undock Z Probe sled

In Prusa Firmware this G-code is deactivated by default, must be turned on in the source code.

G30 - Single Z Probe G30: Single Z-Probe

The sensor must be over the bed. The maximum travel distance before an error is triggered is 10mm.

G75 - Print temperature interpolation G75: Print temperature interpolation

Show/print PINDA temperature interpolating.

G76 - PINDA probe temperature calibration G76: PINDA probe temperature calibration

This G-code is used to calibrate the temperature drift of the PINDA (inductive Sensor).

The PINDAv2 sensor has a built-in thermistor which has the advantage that the calibration can be done once for all materials.

The Original i3 Prusa MK2/s uses PINDAv1 and this calibration improves the temperature drift, but not as good as the PINDAv2.

SuperPINDA sensor has internal temperature compensation and no thermistor output. There is no point of doing temperature calibration in such case. If PINDA_THERMISTOR and SUPERPINDA_SUPPORT is defined during compilation, calibration is skipped with serial message "No PINDA thermistor". This can be caused also if PINDA thermistor connection is broken or PINDA temperature is lower than PINDA_MINTEMP.

Example

G76
 
echo PINDA probe calibration start
echo start temperature: 35.0°
echo ...
echo PINDA temperature -- Z shift (mm): 0.---

All coordinates from now on are absolute relative to the origin of the machine. E axis is left intact.

G91 - Switch on relative mode G91: Set to Relative Positioning

All coordinates from now on are relative to the last position. E axis is left intact.

G92 - Set position G92: Set Position

It is used for setting the current position of each axis. The parameters are always absolute to the origin. If a parameter is omitted, that axis will not be affected. If

X
,
Y
, or
Z
axis are specified, the move afterwards might stutter because of Mesh Bed Leveling.
E
axis is not affected if the target position is 0 (

This value represents the distance from nozzle to the bed surface at the point where the probe is triggered. This value will be negative for typical switch probes, inductive probes, and setups where the nozzle makes a circuit with a raised metal contact. This setting will be greater than zero on machines where the nozzle itself is used as the probe, pressing down on the bed to press a switch. (This is a common setup on delta machines.)

On boards without offline dump support, request online dumps to the serial port on firmware faults. When online dumps are enabled, the FW will dump memory on the serial before resetting.

Usage

D23 [E] [R]

Parameters

  • E - Perform an emergency crash dump (resets the printer).
  • R - Disable online dumps.

D70 - Enable low-level thermal model logging for offline simulation

Usage

D70 [ S ]

Parameters

  • S - Enable 0-1 (default 0)

D80 - Bed check D80: Bed check

This command will log data to SD card file "mesh.txt".

  • H
    - Points Y (default 40)
  • I
    - Offset X (default 74)
  • J
    - Offset Y (default 34)

D81 - Bed analysis D80: Bed analysis

This command will log data to SD card file "wldsd.txt".

Usage
