Ultimaker 2+ Extended Fan Problem

Recommended Posts

Hi, I'm using 3D Printer Ultimaker 2+ Extended for about one year. Recently, I find that the two sided small fans from nozzle does not spin during printing. I tried roll back to the older firmware version. But it still not spin at all.

I believed there is a hardware problem. Something wrong with the fan driver on hardware. May I know which part of hardware controls these fans? You may give me the part number, so that I can trace electronic signals and fix. I am a electronic engineer.

Thanks.

Best Regards,

Okay, I have addressed the problem. The fans are driving by 24V PWM signals named FAN PWM, in which is similar to LED PWM. The PWM signal works fine. However, one fan is dead, since two fans are connected in series, therefore both fans are not spin.

I'll replace the bad fan with a new one. These fans are rated at 12Vdc, 30mm x 30mm x 10mm.

Thanks.

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "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.
