Hello curious aardvark! Thanks for replying!

Yeah, I'm printing via SD. I'm printing PLA at a (default) temperature of 220?C. I've read that this temperature might be too high - and it may be, as I believe some of the material leaks towards the end.

I too have read that those markings can be adjusted via the retraction settings. I've since adjusted some values since. This is my current setup:

- Initial Printing Temperature: 210?C
- Printing Temperature: 210?C
- Final Printing Temperature: 205?C
- Retraction Distance: 3 mm
- Retraction Speed 25.0 mm/s
- Retraction Extra Prime Amount: 0.5 mm ^3
- Additionally, I've enabled the Z hop when retracted setting, "Hopping" at a height of 1 mm.

I'm still seeing some markings on the top layer and some under extrusion on the first layer.
