and it starts, but it does weirdly extrude. When I hit "Extrude 5mm" Manually while nothing is running then it seems like a nice constant flow, but when Printing it somehow stocks, retracts or smth when trying to print. At first I thought its TPU and a new abstract material I have never touched but this currently is the good old Black PLA from Creality that I always used.
I use Cura and just used the default settings for PLA like always.
If you extrude 5mm does your printer actually move 5mm through the nozzle? Also you said you compiled marlin and you changes these three variables. Did you recompile marlin just to change these because that is usually not necessary. You can use pid Autotuning andnsave the values in the eeprom.
Great thought.
Octoprint for sure doesn't know the width of the Nozzle so it definetly won't mean that 10mm would come out of the Nozzle.
So I measured the mm on the filament how much moved. It only moved 3mm when I pressed 10mm Extrude in Octoprint.
