<![CDATA[SoliForum - 3D Printing Community — fan on stepper motor speeds up and slows down]]> 2019-03-31T21:30:30Z PunBB https://www.soliforum.com/topic/18013/fan-on-stepper-motor-speeds-up-and-slows-down/ <![CDATA[Re: fan on stepper motor speeds up and slows down]]> I swapped back over to the right extruder and it is printing good so I guess both fans went at the same time.
will install new fan on left extruder.
Thanks

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

Without replacing the fans with a known good 24 volt fan you have no way of knowing if the issue is the fans or the driver for them.
