So you bought the feeder box on a china/ebay ?

If so you need to use the um2+ estep number * 2. Because um2 extruder motor is 400 step/rev and um2+ motor is 200 steps/rev.

So, search on this forums how to change the esteps on a um2. You will need to use um2+ esteps number * 2 and search how to change the esteps.

Cheap always means more work. Have fun modding!

Indeed sounds about right.

I don't mean that you got it on china, just that probably the accuracy of the gears might give you trouble (or not). Check everything and remember to apply green lube between the plastic gears like um does on his.

Btw if you buy from china better use aliexpress, they have some methods to get some cash back if the seller sells a bad part. If you want to have fun read my adventures on china shops:

Wow. That sucks. Clearly china clones ain't safe. But the main trick with aliexpress is not to vote and test the part as soon it arrives, then you have time to open a dispute before accepting that all arrived.

Hallo. Could you tell at which capacitors you get 2 sparks?

I just receive new motherboard from China, connect it, turned on, and I have abnormal printer behavior. Led screen is off, and and all motors vibrating.

    • "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.
