Texture on Print and Nozzle issue
Hello
I got a issue with my newly assebled P3i. As for the first testprint everything was ok and very smooth, also the first layer applied very good and i corrected around .75mm. then i sliced with the PrusaControl software a model for a case and started printing.
Now the surface looks not even, the texture repeats itself over the whole surface, also the 45° angle has the same repeating pattern. that's not the main issue tho, because i will finish the case off with a coating. the problem is that the nozzle scratches over some infill layers regularly. it does not balance itself out. the first layer was even tho, the problem must have come later in the print.
Before i switch to repetier host and begin to troubelshoot myself, i wanted to ask if you may recognize the issue and know a solution?
Thanks
Roger

I'm not sure, but maybe the setscrew on your Bondtech gear is not properly seated on the flat part of the motor shaft. This would cause uneven extrusion rates during the print.

it was a warping issue, i could not see it clearly because the corners of my print where rounded up, and i did not print it with support because it was not nessesary for that angle. but after i finished, i could see....

What are your speeds like? You could try lower ones - I find that PETG likes a slower speed as low as 20mm/sec sometimes.

There's "even" then there's "even". When you say the first layer is level, do you print some squares and look for over stuffing on the bottom layer and how it varies across the print bed?
My "this is even worse than my Geeetech" prints have all stemmed from the bed being almost level. There's an offset adjust (which only allows +/-50 micron, not enough in my case) which made a huge difference for me.
The other thing that seems to save prints that fail for no discernible reason is taking the time to clean the bed with Acetone.
I'm curious to see what else you come up with, but those may help.
