about a month ago, I had a piece of filament stuck in the extruder. After a lot of work I realized I could not get it out so put in a new extruder assembly. The printer worked fine for a couple of weeks then all of a sudden nothing would extrude. After putting on a 0.6 nozzle, everything worked. So I replaced the 0.4 nozzle. But now things get weird.
With a brand new 0.4 nozzle, I would sometimes get a first layer that looked good sometimes not, but after 3-4 layers the print fell apart. and then nothing extruded.
I tried everything, and then I thought let’s try the 0.6, and it worked. perfect print, the 0.2 same, but when I put on a 0.4 (tried the original and the new one, same thing happened.
Does anyone have any idea what is going on?
Thanks
John
