As slicer independent of a speed test as I could design, it should be pure perimeters! The test consists of long and short segments, sharp and smooth curves

Print with initial layer height 0.3mm. Brim is optional (Although designed for 1mm or 1 line width brim.) Print with 1 perimeter 0% infill No gap fill 0 thickness top.

With 1st layer excluded my record is for 0.12mm layer heights is 25 minutes at 300mm/s peak, 4k accel, how quick can you complete it!
