how to purge the filament from the second extruder
-
Hi guys I don't understand how I can control the second extruder in order to purge the filament before processing. For the first time I use these commands:
G21
G90
G92 E0
G1 E150 F200
M400In Duet Web Control I set the temperature of the second extruder by activating it, but the first extruder always moves.
-
Post your config.g so we can see your tool and heater definitions.
-
playing I noticed something that I don't think is regular, loading a filament in the first extruder loads it at the same time also on the second one, instead if I load it on the third extruder it loads it well.![alt text])

Change to D1You're also using all the same fans for each tool. Is that correct?

First of all, thank you very much, with your help I solved the problem For the extruders I use three fans connected to the same outlet that automatically turns on at 120 degrees. If you see errors in my code or things to improve please tell me. I still have to correct several anomalies but I will ask in another dedicated topic.
