Connecting hotend correctly

Dear all,

this might be a trivial question. I want to connect my new "Chinese" hotend to my Ormerod 2 (Duet V0.6). My currently installed original heater cartridge cable is "splitted" into 2 V+ and 2 GND cables that connect to 2 pins on the duet, respectively.

My question: Do I need to "split" also the cables for the new heating cartdrige (12V 40W) or can I only use "one" connector pin on the Duet (I think this is manly for V+).

Thanks for your help.

Best,
Chris.

It's best to split them, otherwise you may be putting more current through each pin that it is designed for, depending on exactly what type of connector is fitted to the board.

The socket of the board is designed for only 3 Amps so you should split it.

Thanks a lot. Will do so.

They are connected with the KF2510 connectors (and corresponding pins on the board). Any suggestions on the wire gauge when splitting?

Best,
