Prusaslicer time estimate with a custom DuetWifi CoreXY printer

I have a custom duetwifi-based CoreXY and I use PrusaSlicer for gcode generation.

The problem is that the slicer time estimatation is too optimistic - by about 20%. This is after I matched the speed/accel/jerk parameters in the printer and the slicer.

Below you can find additional information on my setup.

 

Thanks!
