Various instruments within the simulator (as denoted on their respective drawings, such as OHC007-1) requires a modification to allow the gauge stepper motor to have continuous travel. Fortunately, we can take the most common variants of these little stepper gauges and easily modify them, instead relying on external electronics to give zero position! The motor is the VID29-02P motor. Be careful, don’t use too much force, and take your time.
