New adoption unit with issues - Ultimaker 2

Recommended Posts

Hello all,

I just inherited an Ulti-2 with a few peccadilloes. The x-axis is skipping and the fans on the extruder are not turning. This is my first run with an ultimaker, so I could use some help in starting this troubleshooting run. I'm not even sure where to start asking questions at this point.

It may be normal about the fans although I admit this is a very common problem. The fans on the sides often don't turn until you are on the second or even 5th layer. Try going into the TUNE menu during a print (or even before it starts when the printer is warming up) and playing with fan speed there. If it still doesn't work it's almost certainly in the connectors just above the head. Cut or slide back the plastic netting and there are white connectors in there. Two of the connectors are connected by a short loop (about 3 inches). Those go to the two side fans.

The third fan - you should test that also - that should turn on either when power comes on or anytime the nozzle is above 50C.

The x-axis is skipping? Can you provide more details? Like this?


Like 9th (pink) or tenth (gray) photo at the above link?

If the filament isn't adhering to the plate but instead the nozzle then almost certainly you need to move glass closer to head. While printing the bottom layer push up and down on the glass to see if that helps. If so then just rotate the 3 leveling knobs the same amount.

Please put ultimaker2 in your settings so I dont' have to reread every thread I post in and can just double check what printer you have by your name.

    • "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.
