I had my first jam tonight. It was on the primary extruder on my flexi-dualie squirting standard ABS. To get the nozzle off, I had to use a crescent wrench to hole the heater block while I unscrewed the nozzle.
After poking and proding and soaking in acetone, I finally got it cleared out. Some dark brown, nearly black stuff was inside the extrusion chamber of the nozzle. Caked on good. Bit of poking with the pick included with the taz and I got it clean.
Then I decided I might as well clean out the flexi while I had the head off. The nozzle came right off! Way easier than the primary. I didn’t think much of it until I decided to put the nozzle back on the primary. I can’t. Its threads are buggered something fierce.
As you can see the flexistruder has nice clean threads and I can hand screw the nozzle back on. The main extruder’s threads are buggered and I can’t even get the damn nozzle started. I have no idea how yall got it on in the first place!
So, what do I do now?
