KEYES ROSTOK Manual And Manual page 89

Note: some firmwares, like Teacup, handle power on/off automatically, so this is redundant there.
M81: ATX Power Off
Example: M81
Turns off the ATX power supply. Counterpart to M80.
M82: Set extruder to absolute mode
Example: M82
makes the extruder interpret extrusion as absolute positions.
This is the default in repetier.
M83: Set extruder to relative mode
Example: M83
makes the extruder interpret extrusion values as relative positions.
M84: Stop idle hold
Example: M84
Stop the idle hold on all axis and extruder. In some cases the idle hold causes annoying noises,
which can be stopped by disabling the hold. Be aware that by disabling idle hold during printing,
you will get quality issues. This is recommended only in between or after printjobs.
M92: set axis_steps_per_unit
Example: M92 X<newsteps> Sprinter and Marlin
Allows programming of steps per unit of axis till the electronics are reset for the specified axis.
Very useful for calibration.
M98: get axis_hysteresis_mm
Example: M98
Report current hysteresis value of XYZ axis.
Proposed for Marlin
M99: set axis_hysteresis_mm
Example: M99 X<mm> Y<mm> Z<mm> E<mm>
Mechanical pulleys, gears and threads can have hysteresis when they change direction. That is, a
certain number of steps occur before movement occurs. You can measure how many mm are lost
to hysteresis and set their values with this command. Every time an axis changes direction, these
extra mm will be added to compensate for the hysteresis.
Proposed for Marlin
M101 Turn extruder 1 on (Forward), Undo Retraction
M101 in Teacup firmware
If a DC extruder is present, turn that on. Else, undo filament retraction, which means, make the
extruder ready for extrusion. Complement to M103.
M101 in other firmwares
Deprecated. Regarding filament retraction, see M227, M228, M229.
M102 Turn extruder 1 on (Reverse)
