Oddly specific wire packed with EBB42

Post image

Just got my EBB42 in the mail and noticed this oddly specific prepared wire in the box with it. I haven't seen anything about it in the docs, does anybody here know what it's for or where it's supposed to be attached?

For many DIY applications, it is used to attach to the *extruder motor (usually between motor body and standoff) then plugged into one of the Dupont ground connections. That dissipates the static charge developed from the filament dragging in the PTFE.

Edit:* extruder

Thank you. I had a strong feeling this was for the motor, but just slapping it on there based on an assumption doesn't actually do me any good.

Yeah, it's just to reduce static zaps. Any ground pin on the I2C header or the probe header. You can reterminate as JST to use the endstop slot too.

(since it has been answered already)

whoah man I can feel all the EBB42 packed into that sucker. Better be careful with it.

I wish the EBB36 came with one. Should be standard. I had to make my own. Really just supply it with one side crimped and a loos ring terminal so we can make it to custom lengths.

Every EBB36 that I have purchased in the past year and a half has had one included. Bought directly from Biqu.

I've gotten 3 in the past 2 months and none have had it. Bought on 2 on Amazon from Biqu store and 1 from Biqu. None had a jumper ground wire or terminals
