Running Duet3 on a Railcore printer. Not having issues getting the part cooling fan to turn on at layer 3 with V4 (PLA). V5 isn't turning on the fan. The V5 gcode is adding a "P0" in the M106 command line. I have to assume Duet isn't recognizing it? Aside from editing the gcode, can the P0 be removed when slicing. I assume this is coming from the new "mounted vs. environmental" fan selection?

You can probably remove the P0 part pretty easily if the Duet3 board has trouble with it. Go to Edit Process Settings > Scripts tab > Post Processing and add the following line:

{REPLACE " P0\n" "\n"}

That will remove the P0 part from the end of each M106 command.

Thank you. I will try this. Cheers!
