I have an issue with my first layer, which suddenly got worse.
What was always a perfect surface on my PEI build plate now comes out like the lower cube.
No changes in the parameters. Printer profile is the same, printing plate PEI is correctly set,
filament profile is also the same (PolyTerry PLA profile 220°/55°).
For me it looks like a slight underextrusion. As the rest is however pretty perfect I wanted to increase the flow rate just for the first layer. However, it seams thats not possible in BS?
Any comments on how I can get back the nice surface? Increase first layer print temperature?
