M107/106 Not Turning Off Fans
-
I am not sure what I am doing incorrect in the slicer to turn off the fans at the end of the print, I also receive an occasional Insufficeint axis's home. config below, I have tried both M107, and M106 in my end gcode in cura slicer and neither seem to stop the fan. I suspect the homing issue has something to do with my delta config but other wise a second home and it prints fine.

@jwebb4616 said in M107/106 Not Turning Off Fans:
M950 F0 C"out3" Q500 ; create fan 0 on pin out3 and set its frequency
M106 P0 S1 H1 T45 ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"out4" Q500 ; create fan 1 on pin out4 and set its frequency
M106 P1 S0 H-1 ; set fan 1 value. Thermostatic control is turned onThe problem with the fan is that you have created fan 0 as a thermostatically controlled fan and assigned it to the tool as the part cooler. So it's not going to respond to commands to turn it off. It will only respond to the temperature of heater1. 45c in this case.
Which fan is where? You have Fan1 created as a gcode controllable fan. Is that the actual part cooler? Once you sort that out M107 etc should work.
As for the insufficient axis homed error, when do you see that? That would happen when giving a movement command before the axis are actually homed.
For good measure share your homedelta.g and bed.g and you slicer start gcode. It would also be good to know what firmware version you are using.

@phaedrux Which fan should be which? Should hotend cooling fan be fan 1 and part cooling fan be 0? I am still learning Reprap and using the configurator, coming from Marlin and Klipper. Thank you for your help
I switched cura to say fan 1 was the part fan and it functions fine turning it on now which it did not before.
As far as the homing error, it seems to happen randomly at the start of prints occasionally, but not every time it homes. a second home always resolves it.
This is an FL Sun Super Racer, with a build volume of 330 mm by 260. The carriage travel section was unclear to me in the configurator so I may have gotten that wrong.

@jwebb4616 The default position for RepRap firmware is that the part cooling fan is fan 0. That's because most slicers insert M106 into the gcode (without a fan number). But you can use any fan you like as long as you map it to fan 0 in the tool configuration (M563). So if you want to use fan 1 instead of fan 0, then add F1 to the M563 tool definition command. That way, whenever a gcode file is being printed which contains M106 commands (without fan numbers) the firmware will use Fan 1 instead of Fan 0. Just remember that whichever fan you decide on for part cooling, you must set it to non-thermostatic mode.
