Hi.
I have trouble with filament that stucks in the nozzle.
It prints some layers, Then the filament stucks.
I have cleaned the hot end and even put in a new guide tube in the isolator.
I suspect that I have made some scratches inside the nozzle. Will that matter?
Somebody who knows what to do?
Is the nozzle blocked or the PEEK element?
I clean the nozzle with a needle from the pharmacies (the protection cap keeps it clean and safe for the user).

The nozzle seems clean, but the filament stops and even gest a small bump.
Try printing with lower temperatures (195° for PLA - 220 for ABS) and less retraction (3 mm / 120-150 mm/s).
Check if there’s no blop before or in the PEEK element.
And like Raby said, lower your temperature.
Dylan
Thanks for replies.
Seems better with lovwer temps.
How do I set this temps im the memory?
You have to change the filament settings in the slicer.
For the preheat function you can change those settings in the LCD menu.
The Load/Unload temperature cannot be changed from the LCD, only with a firmware update…
