Topic: fan on stepper motor speeds up and slows down
I am running semplify 3d.
the fan on the stepper motor speeds up than almost stops.
I was printing with the right extruder the other day and It started doing it so I changed out the fan.
Today I tried to print with the left extruder and it is doing the same thing.could the other fan be going out also or
do I have a board problem.
Thanks
Dale
