Slicers and Tools with multiple heaters

Makergal3D

So I was looking for the forum but I couldn't find information related to this.

I had a machine with a Pulsar from dyze, that has 3 heaters for 1 extruder. When I send something to print all the heaters use the same temperature. But if I want to select one temperature for each section of the extruder, I was doing it manually deleting the M104 from the start gcode manually, because I can find a way to do it automatically in the slicer.
There is any Mcode I can use in the start gcode to do this??
Or should I set the slicer like is has 3 extruders. And create diferent filament profiles for each heater??

@Makergal3D If you want to set the heaters individually, then ideally using M568 in your start gcode in place of M104 is the way to do this. I understand that support for this is not yet implemented in slicers, let alone a way to capture that a material ("filament") profile has more than one temperature specified.

Creating three extruders in the slicer, with a different profile for each heater and then basing the conditional start gcode around this:
https://forum.prusa3d.com/forum/prusaslicer/starting-gcode-for-multiple-extruders/#post-404908
might help? For example:

M568 R{first_layer_temperature[0] -50}:{first_layer_temperature[1] -50}:{first_layer_temperature[2] -50} S{first_layer_temperature[0]}:{first_layer_temperature[1]}:{first_layer_temperature[2]}

(note this is untested!)

Alternatively there may be a way to handle this using the built in "filaments" system in RRF:
