Extension cables?



  • Is there a cable end version of the male connectors the duet uses? I want to make extensions that simply plug in to the existing cables.

    Thanks

    I've never found any. I use the PCB mount version, solder the wires to the spills, and put heatshrink over the joints



  • @dc42 thanks, good idea.



  • Are you referring the the Molex KK style used all over the Duet2 or JST VH used for motors and heaeters on the Duet3?

    The former is available at least, haven't seen/looked for the latter, added benefit of being shrouded:

  • When I was using a Duet 2, I bought cables premade. The only ones I found at almost a meter long. I had to replace the end that goes to the Duet, but that's simple. Just use an exacto knife to depress the tab on the pins and slide the pins out. Slide them into the new connector.

    When I switched to Duet 3, I made my own because the connectors required larger wires. In that situation I used:

    CRJ Male 4-Pin PWN Fan Connector Kit

    Those allowed me to create adapters in order to easily connect my steppers to the Duet 3. All I did was take these those connectors, crimped 22 AWG wire in them (it accepts them just fine), insert them in the housing. Then crimped the other end with the JST connectors that come with the Duet 3. I then slid those into the housing and connected my steppers like normal.

    or try this https://forum.duet3d.com/topic/13658/printed-terminal-extraction-tool if your printer can print sharp enough corners. by all means, knife, screwdriver etc work, but I know I've drawn blood more than once with that method
