I’m using snapmaker branded TPU.
After about 12 hours in the polymaker dryer it successfully printed a 3 hr print job with minimal issue.
That evening i had some trouble with starting what was going to be a 8 hr job (hoped to print it over night). The print is mostly the same as the first batch, just more parts of the figurine in a single job.
The filament suddenly kept spooling in the gear box. It was late, figured maybe it was just hitting an inner part of the spool that wasnt as dry, so opted to just let it stay in the dryer overnight and try again in the morning.
Now I keep having one of either 2 events happen, just from running the “load filament” for a bit to test things out.
It’s like it suddenly misses the hot end’s pipe and starts spooling in the extruder head. Or it gets twisted in the gear drive and just stalls.
To be clear this is just from running load filament for a minute or two to test things. I haven’t even bothered with trying to do part 2 of my print.
Swapped the hot end with the mostly new one that was on the right side, and it had no effect.
Anyone else encounter this? The fact job 1 went with basicially no trouble is what’s confusing me.
