Hey guys, I'm new to the forum. I've built two basic 2 player MAME cabinets with 27" tv's based on a defender cabinet and one single player bartop arcade for other people.
Right now I'm working on my own machine. It is an old Super Pac-man cab that was converted to 1942. All the guts were dead, and it sat out in the sun a long time, so I don't feel too bad about converting it.
I've built the rotating mechanism for the display. It turns on a turntable bearing from Vex Robotics:

It works pretty well, but you can be the judges:
.
I am not having much luck with getting hyperspin or mala to rotate the monitor automatically. I have two batch files that rotate the display to vertical and back to horizontal based. They call the command line .EXE that comes with the motor driver and execute two scripts saved on the device.
I don't need step by step directions, but if you can point me in the right direction, that would be great.
Here is a photo of the mechanism:

Thanks!
