feeder move wrong direction (UM2)

Recommended Posts

Hi all,

The feeder motor of my UM2 not spin well, first of all, it seems cannot move well, then it spins wrong direction when remove and insert material.

Following is the veido for your reference:

When remove material, motor spin clockwise, then I pushed insert material button, it spins anti clockwise.


This printer not connect with PC, we print file only via SD card, I am not sure if SD card affect the firmware or not.

If you have dismantled the feeder and reassembled it you have possibly put it back in such a way that the filament is inserted on the wrong side of the shaft.



Owen, thanks for your reply, yes I reassembled the feeder before, and I am sure it at correct direction, since it worked appropriate for quite long time, before the above problem happened.

I would like you to install the latest Ultimaker 2 firmware through Cura, just to be sure.

Then do a factory reset, if any values have been changed they are back to normal.

If both of these option have no solution, your motor is probably broken.

    • "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.
