Spiral mode external perimeters only print at 15mm/s
I am new to Prusa Slicer but I am having an issue when using the spiral mode. I have the external perimeter speed set to 100% which should be the same as the perimeter speed of 60mm/s. I can see in the preview that the speed is only around 15mm/s though. Duet web control also reports that the requested speed is 15mm/s. I also tried setting the external perimeter speed to 60mm/s and 400% but it never goes above 15mm/s when sliced. I am using version 2.3.0.

Check your min speed per layer time settings under filament cooling. There’s basically a setting in there that says if layer time is below x then slow speed down to a minimum of y.
