Hotend full of PETG - Part ok
Hi,
I have some issues printing with PETG. I have the MK3 kit assembled for 2 days now and all PLA prints were fine. The 2 PETG print ended in a totally soaked up Hotend with PETG. I have no idea were it comes from. The nozzle does not seem to like as shown in the picture into the thread.
Has anyone an idea what causes this? The printed part seems ok for me. Not perfect, but ok. I have no idea how this clogs.
I watched the first 5 layers of this print and haven't noticed anything. I had to leave at some point. I came back seeing this.
I have used Slic3r PE 1.4 and the Prusa PET preset.

Hi PETG is spaghetti making material. I dont like it...
Sugestion:
Clean up everything to the "new state" mechanical cleaning via steel wool and chemical with acetone. Then asemble it together calibrate precisely. IMO this petg turbulence is because of to low Z axis, so try to pull it up via live tune adjust Z in first layer.

I reassembled the nozzle and did a full initial wizard again.
Then did the live adjust as suggested. It is printing right now at height 5mm already. No "build up" of plastic around the nozzle so far. The print does look very good so far. But that's how it was for the last 2 parts also.
I#m puzzled about what caused this huge amount of plastics around the nozzle.
Re: Hotend full of PETG - Part ok
Ok, the problem was the fact that I#m a beginner.
I had some bridges which were not supported correctly so it was printing in mid air which then just curled around the nozzle.
Thanks anyway
