G10 used as opposed to M104 for setting extruder target temperature

Version

Version 2.3.0+

Operating system type + version

macOS High Sierra 10.13.6

3D printer brand / version + firmware version (if known)

Highly modified Ender3 BTT E3mini V2 with Klipper RepRapFirmware flavor

Behavior

• gcode uses G10 in place/as opposed to M104 to set extruder temperature
• Set firmware flavor to RepRapFirmware and slide, review generated gcode in text editor, search for G10
• would expect slicer to place a M104 Sxxx command to set extruder heater target temperature
• G10 command ignored and board uses default extruder setpoint in config file

This is exactly what it should do according to RRF documentation: https://duet3d.dozuki.com/Wiki/Gcode. New versions of RRF have deprecated M104/M109 in favor of G10 with some parameters. See also https://github.com/prusa3d/PrusaSlicer/pull/4553.

If you want the old behaviour, select RepRap/Sprinter firmware flavor. It should work the same as before

If you want to know why the change was necessary, ask the authors of RRF. Closing.
