The hot end fan on my Ormerod 2 has stopped working. I have tested the fan and it is ok. Could somebody please tell me when to go next to find the fault?
Unless you have one of my hot end boards, the hot end fan on the Ormerod is wired directly to +12V and ground pins on the Duet. So if the stepper motors are still working, the problem can only be a bad connection. There is no fuse on the Duet.
