Hello,
I just started using the Ultimaker, I'm using it through my university for research purposes so it was bought as an assembled kit to save time. I've been printing successfully with ABS at 250 degrees for the last week, however during a print today the ultimaker stopped extruding so I tried feeding the filament through manually, but that didn't work. I checked other posts on here about clogged nozzles so I took it apart and removed the clogged up ABS until it was actually feeding through the nozzle (success!). Then, as I was reassembling it, I was tightening the nozzle to the PEEK insulator, and I may have over tightened it as the brass screw attaching the nozzle to the insulator seared leaving the screw thread partically stuck inside the insulator and the nozzle stuck to the aluminium heating element. Clearly, I was annoyed at myself, and that's a lesson learned about over tightening (though I swear it wasn't that tight), anyway I was wondering if:
A) Has anyone else has issues with ABS getting stuck in the extruder nozzle,
&
B ) what could be the possible cause of this e.g. flow rate/temperature?
Thank you!!
