Fans stopped working
MK2/S
I got a Thermal Runaway message. I checked my heating element. It as loose. So I pressed it back in and tightened the screw. After that the Right Side hot end fan would sort of pulse and the left side (larger) wouldn't come on.
Now when I run a self test, neither fan is coming on.
I checked all the wiring, they are plugged in. Unplugged and reset just in case. I checked all the fuses in they are good.. I reseated them too.
The printer powers on. I can tell it to home and it does. The bed gets hot. Just the fans don't run. Is there something wrong with the RAMBO?
HELP!! I'm dead in the water right now.
Re: Fans stopped working
What make is your printer?
At my MK2S my hotend-fan is at the left and the smaller one.
The print fan, the bigger one is at the front.
There is no fan at the right....
Anyway, the pulsing of a fan hints that a cable got intermittend until it broke entirely.
Most likely it isn´t the board but rather the cables...
