4028 fan PWM adjustment
I recently installed Delta 4028 fan, I did the whole thing with 12V and it works, however, there's a problem.
The fan starts moving at fairly low RPM at 47% fan speed and scales up from that as I speed up the fan. I also tried 100hz pwm, it can function on lower PWM, but it needs kickstarting and minimum fan RPM is considerably higher than with 25khz
The question is, what is the best way to rescale fanspeed so I wouldn't need to remember that 47% is actually 1%, and I could use whole range 0-100% in slicer?
