At what point do I determine that I have something seriously wrong?
Just purchased my second mini. First one working great. This second one I had two solid days of prints and now I have not been able to get anything out of it. I think I may have something wrong with the heating element. I can load the filament fine however when I try to purge it will stop feeding and nothing will come out. I can get it to print if I turn the nozzle up to about 255 - 260.
Troubleshooting steps so far:
-Tried new nozzle (when I did this it did not pass selftest and said it failed heating test)
-Taken assembly apart
-Cleaned gears from dirty filament
-Verified set screw is tight from on the gears
-Tried with and without the filament sensor
-Tried to print after cold pull's
-Purged filament
-Checked tubes
I think I've tried pretty much all steps I've found everywhere. If someone can suggest a different one let me know but is it possible I have a defective printer?
