Hi Sander, thanks for the reply.
Normally I clean the nozzle but most of the times 9/10 it isn't clogged...
the pattern seems to be random.
It seems to be underextruding, when I set the material flow higher it doesnt help anything, the problem is the same... underextruding.
The feeder isn't grinding up the material, the pressure is fine, just like the example on the site.
The front and side fans are runing, after cleaning they sound normal but the problem remains.
Kind regards,
Sjors
