    I have been working my way through past forum posts. I have figured out most of the basics but I have a very simple wiring related question. I am not a 'sparky' so would appreciate knowing what is the gauge and best shielded wiring for both the pots and motor power cables?

    If you have a preferred supplier link that would be even better.

    Many thanks.

    I use old usb leads, contain 4 wires , one for a backup in case a wire is damaged and most have shielding built in.
    The pots only have 5Vs running to them and under 50mAmp so a USB lead is rated at 5v - 500mAmps so will be fine and cheap too.
    I have many cords that my bugger of a cat had chewed the ends off so was an easy choice to use.

    Motor cables I use 4mm wire for the Jrks as they can draw up to 45amps, but will draw a constant 12amps. The thicker the better but too thick will make it too awkward and can have to opposite effect. Mine is from the winch power supply cables I still have left over from my old sim.
    Another note is to keep theses short as feasible or a voltage drop will be present from the driver to he motor and route them away from the pot cables too as they can cause noise on the pot line, which makes the feedback readings a little sketchy or jumpy.

    Thanks so much eaorobbie, so simple and here is me thinking I may have order something special in! Sorry for being such a noob but I was finishing off orders for stuff. I now have received or have ordered everything I should need, other than a welder and the steel. That will necessitate a trip to Launceston.

    I live on the East Coast of Tassie and you get pretty used to trying to order stuff in and advance and think of everything you will or may need. Inevitably what you will need during most projects is not available locally. The up side is the beautiful view and mico temperate climate.
