ferrite core

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.
