add M-Code

goair

hi togehther,

how I can add a new (not used) M-Code to the firmware?

kind regards

Best solution is to use the Custom Event System.

there are  some examples here:

https://github.com/repetier/Repetier-Firmware/tree/master/src/SampleEventSystems

or an empty template for G- and M-Codes here:

HI RAyWB

Thank you for your quick response and help and excuse my bad English!

I do not understand the examples, sorry.
I have started like this:

CustomEvents.h:
#define blower_fan

CustomEventsImpl.h:
#define blower_fan FAN2_PIN  // blower fan on/off  mit fan2_pin

but how do I define the command like M336?

//#########################################################################################
//#### MCode addition/replacement
//#########################################################################################


bool Custom_MCode(GCode *com)
{
 
  switch(com->M) {

        //XXXX is the number you want to generate
    case 336:
   
//    break;   
  default:
     return false;
  }
  return true;
}

#endif

kind regards

at least you should have some programming skills , why don´t you look at the  original  commands implemented

in Firmware?

I had look but you are right, I`m not a programmer and unfortunately I understand the composition too little.
...but who dares nothing, who gains nothing.

I had found this

case 355: // M355 S<0/1> - Turn case light on/off, no S = report status
        if (com->hasS()) {
            Printer::setCaseLight(com->S);
        } else {
            Printer::reportCaseLightStatus();
        }
        break;

but how next...

RAyWB

may be you first should describe what you want to do exactly

Hi

I would like to add a blower, which I control via fan1 output with a free M code.

but it should also be controllable via the menu, such as the case light.

Just use the second fan. They can be controlled with P0 for first and P1 for second extruder with normal M106/M107. Repetier-Server will also offer control for both if you increase fan count to 2 in configuration.
