I just ordered some 3mm OD, 2mm ID PTFE tube and 2 new nozzles for each extruder! Hoping it will fix it!
One quick question, tried to loosen the right extruder (the one I don't really use) by loosening the grub screw holding it in place at the aluminium block, when I went to tighten it I did it too tight unfortunately and stripped some threads, stupid mistake. Should I get a new aluminium block or a larger grub screw?
