Custom C gcodes

This firmware implements some special custom g-codes to allow you to configure parameters not available in normal standard Marlin g-codes. You need to use a host/terminal with support for non-standard G-codes or create a .gcode file and "print" it.

Pronterface currently doesn't support non-standard G-codes.

• C10 : Mark the g-code file as a Configuration file
• C11 En Rn Gn Bn : colorize UI elements (C11 E0 to update the screen)
• C29 Ln Rn Fn Bn Nn Tn : set probing mesh inset (Left, Right, Front, Back) in mm. N amount of grid points of the mesh leveling and T the probing temperature
• C100 Xn Yn Zn : setup minimum physical limits
• C101 Xn Yn Zn : setup maximum physical limits
• C102 Xn Yn : setup bed size
• C104 U1 Tn : unlock the maximum hotend temperature (limited by thermistor calibration table)
• C108 : cancel screens waiting for user simple confirmation
• C125 Xn Yn Zn : setup the park position
• C412 Mn : set run-out sensor active state (M0:LOW, M1:HIGH, M2:MOTION)
• C510 Un : lock/unlock the screen (C510 U1 to unlock)
• C562 En : invert the Extruder (E1 to invert)
• C851 Sn : Set probe Z feed speed (F) in cm/s

After changing any parameter, send an M500 to save to EEPROM and make it permanent.
