Hi all, my prints are almost perfect... One thing letting them down is marks all over them. Im pretty sure its not retraction because when i turn retraction off there still there. Im also pretty sure im not over extruding because ive tride using PLA at 0.93 extrusion and the marks are still there. I have attatched an image, please help i have no idea what they are...
Well if I were you, I would watch it while it's printing to try to see when the extra marks are created. That's the best way to know for sure.
As for other guesses, you might want to try adding 1-2mm of retraction vertical lift. That could be a good test to see if this goes away once the nozzle is moving up in the air.
