I’m wounding if anyone has an idea what is happening.
Every time I try printing a big model, about 3-4 hours in, no more filament is coming out of the extruder. There’s plenty on the roll, the roll is not jammed on itself and the extruder motor is not jammed either (no clicking noise as it does if the nozzle was clogged).
The extruder motor spins like everything is fine, but no material is coming out of the nozzle head. If I try to pull out the material, it gets stuck on the on the extruder motors gear. But it still won’t push the material down through the extruder, just spins like it’s making no contact with the gear, yet it must be to some degree or I would be able to pull it out.
Every time, the fix is just unload and reload the material and everything works again, until your a few hours in and it does that again. So I can’t print any big models that take a long time as a result, which is everything I need to print right now.
I just replaced the extruder, nozzle, and temp sensor/heating coil with oem parts in hope something was wrong there, but it made no difference. This printer has printed thousands of hours at this point, so it’s far from new.
The material btw is z-abs. No materials have been used with this printer besides Zortrax materials. There is nothing blocking the spool from unwinding that I can see.
Any ideas as to what could be happening? I’m at a loss as it seems to defy physics to me (can’t have a free spinning gear and yet the material is caught on the gear)
Thanks in advanced.
