I could use some help! After a long hiatus, I’ve started trying to use my ToM again, and I’m getting terrible results. The plastic is, at best, coming out big and blobby with what looks like air-bubbles in it, but it is also often striping on the hobbed gear and thus not coming out at all, although it starts up again if I push on the filament a little. Attached are some pictures of a raft printed today.
Any ideas on where to start debugging this? I’m guessing the bubbles are because the ABS has absorbed too much humidity, but I Think I should be getting a thinner, neater raft than this, and I don’t know why the extruder would be so unreliable.
Feedrate and travel rate at 20, hot-end at 240C.
