Where do I go from here?
Good morning, I have been fighting terribly with my Prusa Mini. I have two MK3S printers that never give me any trouble I can't figure out. The mini is another story. I *think* I have underextrusion issues but I don't know anymore. I've tried so many different things after reading other people's posts. Would someone be willing to take a look at these photos and tell me what you would try next? I noticed that cranking the temp for my filament did seem to help a bit. This was printed in a vertical position - not lying flat. Sliced in Prusa Slicer and printed with Solutech PLA which doesn't give me any trouble on any machine I've ever used it on. Thanks for any thoughts.

The 1st pic looks like a view from the top as printed. Any chance you've used different Linear Advance values between the 2 printer types? Those rounded (dogbone) corners look like typical LA calibration issues.

Hmm, that's a little over my head but here's the starting code in my Prusa Slicer. I don't remember ever changing these but maybe I did somehow?
M900 K{if printer_notes=~/.*PRINTER_MODEL_MINI.*/ and nozzle_diameter[0]==0.6}0.12{elsif printer_notes=~/.*PRINTER_MODEL_MINI.*/}0.2{elsif nozzle_diameter[0]==0.6}0.04{else}0.06{endif} ; Filament gcode LA 1.5
{if printer_notes=~/.*PRINTER_MODEL_MINI.*/};{elsif printer_notes=~/.*PRINTER_HAS_BOWDEN.*/}M900 K200{elsif nozzle_diameter[0]==0.6}M900 K18{else}M900 K30{endif} ; Filament gcode LA 1.0

I cannot find any LA routine in the Mini Firmware (4.2.0). For testing, I have printed 2 towers with different LA settings (PrusaSlicer M900 K0.05 to K0.50 changed the settings every 10mm), but I cannot find any difference or changes.
have I missed something?
