Ultimaker 2 X Y motor - where to get it?!

Recommended Posts

Hi Guys,

I am really struggling to find the correct replacement motor to buy, on these forums no one has really answered the question very clearly.

What is the motor called for a standard UM2 X or Y. And in the UK where is the best place to get one?

Also can someone please explain to me what a stepper controller is? As i have read a few people saying to try changing that before changing a broken motor etc..

Thank you in advance.

Stepper controller is the chip of the board that controls the data sent to the motor. You can’t change it on um2 board because is soldered to it, other printers use removable stepper chips that can be removed/upgraded.

The motors, check the sticker behind yours, you have a long list of letter with the definition. They are easy to find on any pololu reseller, or at a um reseller/distributor.

If you buy the motor elsewhere (cheaper) you will need to twist the pairs (red/blue - black-green) and crimp the cable on the proper socket, or cut one you have and resolder the cables.

A fast google:

Crimping or soldering isnt an issue at all for me.

Thank you for the link. All the google searches I did, didn't actually come up with any retailers, and lots of confusing messages about them being different sizes and will they fit.

I cant find a reseller in the UK that actually sell them. Most seem to be US based and postage etc.. i very expensive. If i search for that model, I cant seem to find anyone selling them, i get alot of NEMA 17 motors? Any idea?

I bought the exact model on a reseller here in spain. In uk zappautomation doesn’t seem to have the one with the same length.

I would try ebay for respetable sellers. Found one that the sticker matches the one of um and its pololu brand

    • "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.
