Hello,
I have an A1mini. I’ve been experiencing this problem for quite some time. It also looks like it’s getting worse, but I’m not sure about that.
Basically, I am experiencing what looks like overextrusion but only on the smaller areas of my prints: the top layer is rough and coarse, sandpaper-like. Some pics:
The fact is that I am using same file, same presets and same filament (PLA) as before: I don’t know why this is happening. I ran an auto-calibration for the K factor and also did a manual calibration for the flow rate. Nothing changed. Also important: this happens both with the standard presets and the custom ones.
What could I do to solve this issue? Thanks to everyone who is willing to help!
