I have been able to print several pieces on this mini 2 without issue up until recent.
Midway through a print, it just stopped feeding fillament, and I noticed when pulling out the remaining, there was the typical “mouse bite” from the feeding gear.
I have tried several hot and cold pulls to clear up whatever has jammed, but cannot seems to clear it. I can press extremely hard and get some filament to come out, but its more or less in a pigtail fashion and maybe can extrude only about a 1/2 inch to an inch.
The funny thing is, this happened to the original tool head in which I replaced, then was able to print just fine for a few prints. I noticed that when I printed fine resolution, this happened again to the 2nd tool head. Sucks that now I have burned through 2 tool head units and hope to be able to clear up whatever the issue is on this one as I sheared off the hot end trying to unscrew it on the original head.
Anyways, any ideas on how to free up this jam? Any idea what might be causing this to happen all of a sudden with 2 different units? I have used this PLA and ABS from matterhackers for quite some time now and used it several times successfully.
