Does anyone have a need for a new cannon gearbox? Mine is crunchy, jumps a bit in certain spots. Electronically it parks in the 'home' position properly each time because it's quite sloppy it doesn't always align with the rail. There's a lot of play in the mechanism.

I was thinking of making a new modern part using a geared stepper motor, an absolute position encoder and arduino micro with custom software. It's easy to detect the voltage to start the motor and to also send back 'home' and 'at mark' positions using arduino output lines instead of actual micro switches. This means no fiddling around with those two micro switches.

Pinball test 14 - gun motor would still be used to position the gun then a push button on the arduino pcb would be pressed to load the position both positions into the arduino.

If there's enough interest I will make it available when I've finished it. Not sure of cost but I really want the cannon fixed and I don't want second hand parts.
