ferrite core

Recommended Posts

Is the UM2 supposed to come with a ferrite core? I'm following the installation instructions for my new bondtech extruder and it mentions one. After removing the cover I notice mine didn't have one in the stepper cables.

It depends on how old your machine is. The earlier ones didn't have any IIRC. Also check behind the cover on the inside of the printer if you haven't already (I'm assuming you have though).

Thanks Robert. Yep, that's how i realized I was missing one.

I assume adding one to an older um2 (mine was bought Nov 2014) would be a good thing? Or at least, not hurt anything.

Anyone know the size of the one used, or where I could buy one? Thanks.

    • "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.
