    Hi guys

    Ive set my rig up as a 3 dof with 2 wheelchair motors. They are connected to a 12v server psu. There's no third ground wire in the socket. They are not connected to the rig as they are on a wooden frame. Ive added a wire from the motor frame to the rig frame. Everything is up on plastic/wood/rubber

    When i drive and there's a hard hit in the rig from a gearshift or something similar HE pedals just fails and i have random dropouts on the others. Ive tried connecting the USB to different sockets and the power to a different power source on another line.

    Edit: Looks like its my HE sequential shifter causing the issues
    Any ideas?

    Here's the rig

    On the SimTools side lowering the Game manager % down a little, try 97%, can help reduce spikes in things like crashes.

    But you could also have a USB bandwidth issue, as in most cases USB ports share controllers.

    Thanks but it was definitively the HE shifter. Bad usb connection so when it drops or shorts of what it does it wrecks everything.
