UM2 Side fans always on, centre fan always off.

Recommended Posts

Hey everyone,

Apologies if this has already been mentioned, I did use the search function but either I'm doing it wrong or it's not there.

The other day my UM2 seemed to short out, after I'd checked everything to make sure nothing had blown I turned it back on and the side fans are acting like they're on 100% permanently. There's just no way of controlling them. Is there anything I can do to sort this without having to resort to a new board? Everything else works fine, it prints absolutely great still, just the fans are annoying when the printer is idle.

Also, for as long as I can remember the centre cooling fan doesn't work, I tried replacing the fan but that's made no difference.

Please help!

Thanks in advance x

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
