Print cooling fan just run if set to 100%
Hey guys, I have two printers, both run with an Radds board an have the same Firmware. The print cooling fan runs perfect on the one printer, i can adjust the speed but on the second printer the fan just run if I turn the speed to 100%. Can you help me please? There is one difference between the printers. The one which runs fine has an original arduino due, the one with the fan problem has an clone arduino due. Is this the reason or do i have a falty radds board?
Best Regards

Have you tried switching the 2 fans to see if the good fan also stop on the bad radds? Maybe fan has just more friction. Also watch out for polarity of course.
