I have Tronxy XY2 Pro, that has worked flawlessly for about 6 months, but the fan on the hot end (the one for the heat break) has died. So I thought no problem, I'll grab a replacement fan.
So 3 fans later from Amazon I've decided I'm missing something. Using a Multi-meter, there appears to be a permanent 24v supply to the fan connector, but none of the fans are turning.
The original fan was definitely knacker, it was stiff to turn. The new fans are brand new free turning etc. but are not starting.
Anybody any thoughts?
