Setting up Mame / Mala with rotating CRT (Mrotate4)

Ropi Jo:
OK. Just checked my wiring. My end stops are NC, so open when the mech hits them. But I have a NO spare on each so can take that and fire a timer relay to do almost anything... single shot, set single shot pulse duration, set continual pulsing, etc.

And... my MOBO does not have a printer port. Doesn't even have a PS2 for keyboard or mouse.

I would put some pics but struggling with that. Must be a guide on here somewhere.

I will check malaori and iRotate ASAP.

Thanks again.

Ropi Jo:
Somehow I managed to upload a pic so I'll try some more...

Please remember this is work in progress...

What I meant is that if you have the motor/actuator voltage running through the limit switches like this example, you would need to run the keyboard encoder inputs through two other switches. (not shown)

Mixing the motor/actuator voltage and the keyboard encoder inputs is not a good idea. ;)

I think I'm with you on that Scott.

I've got 24V running the rotate elecs, so at the end of the rotate I would get 24V on the NO. This could operate a relay that would make any switch on the JPAC via the relay's no volt contact. The 2 circuits would be isolated from each other.

Yeah, that makes sense. :cheers:

Two regular relays -- one controlled by the NO of one limit switch and the other controlled by the NO of the other limit switch -- and one time-delay rely to interrupt those two JPAC input grounds during boot to avoid a Windows "stuck key" error.
