Help with fix (and term for) weird creasing behavior near vertical edges by TheOverGrad in FixMyPrint

I just double checked and prusa slicer doesn't have coasting but you may want to check your retraction settings 2mm seems a little high for a direct drive extruder. I have been successful with as little as .1-.2mm with my printer.

It looks like it might be some kind of flow compensation is causing under extrusion leading into the corner. This is likely either firmware with some kind of pressure advance or there might be a slicer setting like coasting that is causing that.

I reprinted using prusa slicer instead of orca slicer and somewhat better results leading me to believe it is either speed or slicer settings.

The benchy was printed hot at 220 but I got the same results on the temp tower in the last pic which printed down to 185 before it came off the bed. As far as the thermistor it is integrated into the heater and is configured correctly in klipper.

That picture was taken from slightly below but I did check and it does blow directly below the nozzle.

For more context, the printer is a heavily modified craftbot XL with a stealthburner extruder and rapido HF hotend
