add m-codes

RAyWB

Hi,
as i want to use repetier fw also for milling i think about adding m-codes like M3 , M5  for spindle on/off an a couple of other commands

is there something special i hav to take care of?

i want to add the on/off commands similar to the power on off.

just adding the m3 / m5 like this:

        case 3: // M3 - Spindle On
#if SPINDLE_ON_PIN>-1
            Commands::waitUntilEndOfAllMoves();
            previousMillisCmd = HAL::timeInMilliseconds();
            SET_OUTPUT(PS_ON_PIN); //GND
            WRITE(SPINDLE_ON_PIN, (POWER_INVERTING ? HIGH : LOW));
#endif
            break;
        case 5: // M5 - Spindle Off
#if PS_ON_PIN>-1
            Commands::waitUntilEndOfAllMoves();
            SET_OUTPUT(PS_ON_PIN); //GND
            WRITE(SPINDLE_ON_PIN,(POWER_INVERTING ? LOW : HIGH));
#endif
            break;


has anybody some ideas how to realize other "mill-specific" codes like tool length measurement etc?

thanks for any thoughts

Except that PS_ON_PIN is for the PSU and not spindle this is ok (also neglecting the spindle direction).

For tool measurement I'd add a z-probe( which is in this case a switching plate pointing up like usual in cnc) and would place it at a defined position. Then you could measure z height at that defined position and get the correct height. Just like G29 does but only at one point. You could even rewrite G29 to use only the first point.

OK, thanks for the info and pointing at my mismatch !
I´ll also implement the G0 as written in the "G0rapidmove" discussion
