Format

This is the new format which allows multiple extruders. The old format is deprecated. The old “one-extruder-only” configuration options will still be valid for backward compatibility, but it is recommended not to use them.

For example where before you used Extruder_steps_per_mm you must now use Extruder.module-name.steps_per_mm.

Here are the G-code commands currently supported by the Extruder module : 

  • G0/G1 : Move to the given coordinates. The F parameter defines speed and is remembered by subsequent commands ( specified in millimetres/minute ) (command is modal)
  • G10 : Do firmware extruder retract
  • G11 : Do firmware extruder un-retract
  • G90 : Absolute mode ( default ) : passed coordinates will be considered absolute (command is modal)
  • G91 : Relative mode : passed coordinates will be considered relative to the current point (command is modal ). Make sure you use G92 E0 to reset the extruder position every layer.
  • G92 : Set current position to specified coordinates ( example : G92 E0 )
  • M17 : Turn the active stepper motor driver's off
  • M18 : Turn the active stepper motor driver's on
  • M82 : Set absolute mode for extruder only
  • M83 : Set relative mode for extruder only
  • M84 : Turn the active stepper motor driver's on
  • M92 : Set this axis' steps per millimetre. For example M92 E100 to set for the currently active Extruder, and M92 E100 P2 to set for the second extruder.
  • M114 : Displays XYZ position, as well as the E position of the currently active Extruder
  • M200 : Set E units for volumetric extrusion - D<filament diameter> set to 0 to disable volumetric extrusion, for example : M200 D3.0 to set for the currently active Extruder, and M200 D3.0 P3 to set for the third Extruder.
  • M203 : Set maximum rate for axis, set E for Extruder axis or V for volumetric extrusion limit, for example : M203 V10 will limit extrusion moves to no faster than 10mm^3/s. M203 V0 disables.
  • M204 : Set acceleration in mm/sec^2, E<nnn> sets extruder only move acceleration, for example : M204 E500. P selects the extruder, uses the currently active extruder if omitted.
  • M207 : Set retract length Smm Fmm/min Zzlift/hop Qfeedrate mm/min, for example : M207 S4 F30 Z1
  • M208 : Set retract recover length Smm surplus to the M207 S* Fmm/min, for example : M208 S0 F8
  • M221 : S<flow rate factor in percent> : Set flow rate factor override percentage for current extruder
  • M500 : Save volatile settings to an override file
  • M503 : Display volatile settings
