Filament Uneven? Poor Adhesion?
See picture, wondering what to try next.
Did a full calibration, cleaned the hotbed with acetone, nozzle is clean, at least externally, using Prusa Filament and its beading up and catching.
Thanks in advance for your assistance!
RE:
What is the filament?
Acetone is not suitable for regular cleaning, it is useful after a few hundred prints have left residues on the print sheet.
Clean the sheet with dishwashing detergent (Dawn/Fairy) and plenty of HOT water, rinse well and dry with a fresh paper towel. Handle by the edges only.
Then run a first layer calibration and if you are unsure show us a picture of the resulting print *on the print sheet*.
Cheerio,
RE: Filament Uneven? Poor Adhesion?
How does the internal Z calibration print (zig-zag rectangular lines and single solid square) look?
In particular, do the beads have a nice oval shape, and does the square show nice even strokes?
