    Not yet, but the rod ends and the pots have finally arrived :)

    Still missing some things, among others, 1 jrk...

    The levers are done, and so are the rods :)

    Aah, just thought about the angle on the levers... Is it better that the angle is 90 degrees?

    Maximum effective torque is when the lever is 90 degrees relative to the rod.

    Thanks, I'll have to shorten the rods a bit then, I don't know why I thought they should be level with the ground...

    Have anyone tried to make mechanical stops to prevent the motors from spinning around and damaging the pots?

    Would I risk frying something? I will of course make a safety switch.

    I have no idea, as i haven´t tinkered with the jrk yet :) I just thought that it might be a good idea...? If the pot fails or something, an electronic limit wouldn't help i guess?

    Hi @Raredog , nice to see someone else from DK here :) Good luck with your built, you'll enjoy, for sure.

    I have a hard time finding steel tubes here in our country, may I ask where do you buy them?
    Thanks :)

    I've decided to cover most of the sim in mdf.

    Behind the glass I will make a box for the electronics

    Nearly finished with the box, the last jrk arrived to day.

    Also made a "dashboard" of a kind, but might have to make some vents for the wheel...

    Where can I find some sort of rough setting for setting up the jrk's?

    Fans and Heat sinks are 100% Mandatory. NO questions asked. Despite what Pololu may claim.

    Thank you very much :)

    I have just added the heatsinks, the fan are still on the way from China, but I'll just use a temporary one while testing.

    Got the left motor set up, but can't get the right one to work? If I measure on the jrk, it seems as no voltage is passing thru?

    JRK utility says: "error detecting motor direction"

    Error 1x0001


    What to do?

    Found out; bad soldering on the motor.

    Both works now :)

    Now I just need to figure out simtools...
