  1. Hi, I have a critical issue with filament. Issue: PLA Filament does not unload when press the unload button, motor sound was normal, but the filament did not move. Observation: I heated the nozzle to 220 degree, then I lifted the lever on decoupler and tried to pull the filament out manually, but it is not moving. I opened the cover of the decoupler.

  3. Just want to share an update of the finished print. It actually looked alright, not as good as PLA but also not a complete disaster. I am going to try to lower the nozzle temperature to 235 and bed temp to 90 to see how the print looks.
  4. Hi, When I printed with CPE+ on Ultimaker S5 with the default profile applied glue stick on the bed before printing. The first layer looked really bad and I don't know if that's normal. Could you take a look and give some advice? The nozzle was also covered with white CPE+ filament when I abort the print. Is this because the bed is too hot? How can I change it so it can look as good as I print with tough PLA? Best
