Toolboard 1LC shield termination

[nmsmith89]

Hello!

I'm currently wiring up my new RatRig VC3 and I bought a shielded 24 AWG 4 conductor TPU cable for the Toolboard 1LC on the printhead.

My question is:

Where should I terminate the drain wire?

I'm using a 4-pin Molex Nano-Fit connector at both ends of the cable. Would it be sufficient to connect the drain to the 24V ground that heads to the Toolboard (ie just on the printer end)? Or both sides? Frame? Connecting to the cable V- would be ideal since the cable would still be detachable.

I don't have a lot of experience with shielding and EMI so the help is appreciated.

Thanks for your help in advance!

@nmsmith89 yes just at the supply end is good.

@dc42 can I just tie it to 24V- on the supply side or would it have to be something like the frame?

@nmsmith89 the negative input terminal to the Duet main board is a good place. The ground pin of an IO connector would also be a good place.

@dc42 As always, thanks for your help!
