    Default 18 pin cable

    Hi
    I have the original Craftsman Compucarve A series CNC.
    I had it in storage for several years. I decided to get it out, clean it up, and get it going again.
    Unfortunately I found that the 18 pin cable ribbon to the spindle head was damaged by a rat.
    I called Carvewright to get another one but I was told that the ribbon was discontinued since 2007 and I would have to upgrade my CNC to get the 14 pin ribbon. That would cost hundreds of dollars.
    I can’t afford a new machine, so I’m hoping to get one from someone who upgraded their machine.
    I sure appreciate it.

    Sorry to hear about your 18 pin cable. Due to it's thinness it would let conductors snap inside the plastic leading to many problems from the bit driving into the board and jamming, Air Carves, Board Sensor reading errors. I will post your request on the CarveWright facebook page as it gets allot of attention. Ask them to come here and contact you.

    A cable may be available through electronics suppliers. Please measure the exact length and width of the cable, and if possible the spacing between conductors (will likely be in metric). Also a close-up photo of one end showing the conductors. I buy electronics regularly and may be able to find a supplier for you.

    I have not found an exact replacement in stock - most are much smaller in length. I have a few suggestions.

    Samtec offers a 20-pin cable in the length that you need. I would try trimming one with a razor blade down to 18 pins. Unfortunately it is not stocked at the electronic distributors, so there will be a lead time from the factory. Here is an example:

    It would be worth your while to contact the factory directly to see if they can get you exactly what you need:

    eBay has Chinese sellers offering 18 pin cables, but not in the length that you need:

    It might be possible to use a cable extender to join two shorter cables to fit your machine. I did not find an 18 pin extender, but a 20 pin could work if you insert the flex cables to the one side. The extender would need to be mounted on something ridged in the machine.

    Another possibility is to use two 14 pin cables. Cut 4 positions off one, trim the edge of the other, and use the two in place of the 18, taped together. It may sound a little crazy, but I think that it could work. Be advised that my 14 pin cable from CarveWright is only 21" long.

    If it were me, I would first contact Samtec. If that didn't pan out I would try two 14 pin cables as described.

    Sorry I could not be of more help.
