Third fan UM2+ not turning on

Recommended Posts

Posted · Third fan UM2+ not turning on

Hi everyone,

I decided to replace my original hotend fan with a new ,more silent one. When I put the new one on and turned the printer on , fan was not turning on. I checked the connections ,all the wires, heated the hotend above 40 C and still nothing.... Tried to test the fan and its working so thats not the problem ither... any ideas?

Best regards

Luka

One thought, have you tried re-connecting the old fan ?

I did and it didnt work

Could it be smtg on the board?

I've tested the board on the third fan connection and it reads about 2V when the hotend is below 40C and when heated its 0.52V is that normal values?

Connected directly to the board still not working, but works fine when tested with battery
