Toolboard W Hemera/Tool Distrubution Board Cat6



  • Ello all!
    Working on building my first custom printer build and I have a question.

    I have the Duet3, Toolboard, And Tool Distrubition (on a Hemera) running on 24V. Instead of running two wires from the toolbard (CAN and Power) would anyone advise using just one Cat6 cable? I don't see any reason why not, just wanted the forums input on it.

    Thanks!



  • the wires in the cat6 are not large enough for carrying the 24v power at the required current.

    CAT 6 cable can use 23 or 24 AWG conductors. If you use 23 AWG cable, and you use 2 pairs in parallel to carry the power, and your hot end uses a single 24V 30W heater, then IMO CAT 6 cable should be OK. But don't use RJ45 connectors, because using multiple contacts connected in parallel to carry a lot of current is not advisable.



  • Normal Cat6 cable sheathe is PVC or similar meant for laying down once and not being moved repeatedly. It will wear down from 3d printer movement and bare your wires. I would suggest using cable that has a different kind of sheathing material.

    Good point, I overlooked that.
