which x-y stepper motor to buy for UM2

[jroen 0]

Hello,

My Ultimaker 2 (2014) makes a cracking sound comming from the Y - motor and it gets worse every day.

This should be the motor according to the github specs:

https://github.com/Ultimaker/Ultimaker2/tree/master/1182_X%2CY_Motor_(x2)

But what are the true specs, is it a NEMA17 0.9 deg?

Can I replace it with this one?:

If so I think I should only shorten the shaft and remount the connector.

Strange thing I can't find it along the ultimaker spare-parts webshop.

Hope you can help me out.

I just took it out and it seems to be SY42STH38-1684A (both x and y) and they run very well.

So I think the GT2 belts are wearing out a bit because they make some squirking sounds.
