What can I do to figure out why the right cooling fan is not turning on?
I'm having the same issue but a new fan didn't work. And the left fan turns on as soon as the printer is turned on and its super fast. 2234 hours on this printer with a 90% success rate, this is the first issue I have had with this printer. Thanks you all for your time and have a great day.
Make sure the fans you get are 24 volt ones.
its was a replacement fan from makerbot. The crazy thing is the left fan turns on and spins up faster then normal as soon as the printer turns on. I smelled magic smoke when it first happened. I want to find a new mightyboard but they are hard to find. Does anyone know if you can upgrade to a new board?
Possible blown mosfet...
Filament fiber got caught up in the fan axis and caused it to not work. Replaced the fan, working good again.
Both are connected. I will purchase new backup fans. Any suggestions on a good source?
first check the connections
