UM2+ Feeder extrusion problem

[murtang 0]

Hey.

I have just updated my UM2 to UM2+. Unfortunately, I now experience problems when printing. The material is not coming out smoothly of the nozzle. If you lift up the tension lever on the feeder, it sometimes helps, but I cannot sit there all day holding the lever when printing.

One thing I noticed is that the feeder wheel gets "offset" when I insert the material where I would expect the tension lever to be the one that moves away from the material. I have added a picture of the feeder with the "offset" feeder wheel. Is it supposed to be like this? I would be very happy if one of you could upload a picture of your feeder.

For the record, I use 2.85mm PLA filament

Thanks in advance

Mine is centered. Something is broken in your feeder. Open it up and see what is going on inside - something popped out of it's axle or something.

It's supposed to be like this :

If you open it, be carefull to not forget anything then !

Heres a tutorial on how to dismantle a UM2+ feeder and how to reassemble it:

Thank you all very much.

I opened up my feeder and I can see that my feeder wheel is missing the outer ring which should fix it in the hole.

I will try to order a new feeder and replace it.

I don't think you'll be able to order just a feeder.

Is your machine new ? What happened ?

It was a UM2 that was updated to UM2+. It was updated at the store where we got the UM2 in the first place. After getting it back, I started noting the problems with the extrusion and the feeder. I got the feeder wheel replaced at the store under warranty and it is now up and running perfectly.

We do not know whether it was broken when we got it, or it has been weak and broke doing the first prints we made. I have not found any broken loose parts inside it or around the printer.

Hey guys,

 

same problem here. Does anyone know a part number for this broken metal ring thingy? I quickly looked through the source files of 2+ but could not find this part. Don't really want to buy a new feeder over this small metal ring...

That's a simple ball bearing from stainless steel, part no. 1974 (if i'm not wrong)

If your reseller doesn't offer it separately, you can buy a new feeder, or ... ... well, those things are fairly cheap standard parts.

 

Just measure the main dimensions of the broken part, that's all you need. It should be:

outer diameter: 12.0mm

inner diameter: 8.0mm

width: 3.5mm

 

Also called "MR128-ZZ"
