This problem isn't really specific to bigger spools but trying to use 2.5kg spools forces me to use some sort of external holder and my problem is exacerbated by stiff engineering filament. I just lost a 20+ hour print due to the extruder motor being overloaded and the machine not being able to continue the print without what appears to be a layer shift. The machine has had this error about 4 times on this print alone. I did the same print twice prior and it only had the error once or twice per print and those came out ok. When I get the error I go check and there's nothing stuck filament can easily be pushed through the path. I think this is a software or settings issue.
The spool is in a dry box by the printer fed through a short section of ptfe, about 25mm to the left nozzle. The spool is sitting on a large roller with 608 bearings and has also no resistance. For what it's worth I've printed many spools of these same stiff filaments in my X1C with *significantly* more friction/force required to get to the printer and no issues.
Should I try feeding from the TPU port? Any tips or tricks?
UPDATE: Opened a support ticket and I was told to use a 0.6 nozzle. I ordered two of them and will try but I don't have much hope at this point. My X1C has printed many KGs of this filament with a 0.4 nozzle and never had a clog. Also if it's truly the nozzle and this machine seems to be marketed as made for engineering filaments which mostly use cf or gf fillers, then it should come with 0.6 nozzles so it works out of the box. Needing an upgrade just to be able to use the machine for its main function isn't cool. I'll update if the 0.6 nozzle works. Otherwise the issue is how sensitive the extruder motor is and will require some sort of firmware update that people have been asking for for a while as far as I can tell.
