Mcode Summary
| Mcode | Parameter | Command | Description |
|---|---|---|---|
| M0 | Program stop | ||
| M1 | Program stop | Optional program stop switch is not implemented so M1 is equivalent to M0 | |
| M2 | Program end | ||
| M30 | Program end | ||
| M60 | Program stop | ||
| M3 | S | Spindle on - CW | S is speed in RPM |
| M4 | S | Spindle on - CCW | S is speed in RPM |
| M5 | Spindle off | ||
| M6 | Change tool | No operation at this time | |
| M7 | Mist coolant on | Note that mist and flood share the same Coolant ON/OFF pin | |
| M8 | Flood coolant on | Note that mist and flood share the same Coolant ON/OFF pin | |
| M9 | All coolant off | Note that mist and flood share the same Coolant ON/OFF pin | |
| M100 | active comment | Run active comment in sync with motion | M100 ({out1:1}) will turn out1 on in between the moves surrounding this line |
| M100.1 | active comment | Run active comment as soon as it's parsed | M100.1 ({g55z:0.1}) will set the G55 Z-offset to 0.1 as soon as it's parsed |
| M101 | active comment | Delay motion in this point in the program until the active comment evaluates true | M101 ({he1at:t}) will make the program wait until heater 1 is at temp (The value must be true or false, not numeric.) |
M2, M30 Program End
program END (M2, M30) performs the following actions:
- Axis offsets are set to G92.1 CANCEL offsets
- Set default coordinate system (uses $gco)
- Selected plane is set to default plane ($gpl)
- Distance mode is set to MODE_ABSOLUTE (like G90)
- Feed rate mode is set to UNITS_PER_MINUTE (like G94)
- The spindle is stopped (like M5)
- Motion mode is canceled like G80 (not set to G1)
- Coolant is turned off (like M9)
- Default INCHES or MM units mode is restored ($gun)
