I just installed a new hex hot end and made a few prints no problem. However I started noticing that about mid-end of the my prints the extruder would stop extruding and I would just get flaky bits.
I tried adjusting the two tensioner bolts and I loosened the bolt holding the carriage. I don’t think the nozzle is clogged because when I push down without the idler carriage the filament comes out fine. Then when I hit the extrude button everything seems to be fine also. But when I start a print it extrudes for about the first 20 seconds and thins out then nothing comes out again.
I thought my tensioner was too tight but when I loosen it it doesn’t extrude at all. Is the bolt supposed to eat into the filament so that it actually makes an indent into it?
