Has anyone ever married VSA via an SSC-32 board with a step motor? I know RC servos work, but if you really wanted to do some heavy lifting... has anyone been successful? what hardware? what was your application? etc.

Thanks in advance,

A stepper by itself does not have an absolute positional feedback mechanism. You would need to add something like a potentiometer to the shaft and then have a separate controller board sense the position and communicate to the SSC-32 board. If you are looking to move heavier loads I would suggest you look into the servo gear boxes at Servocity. They take regular servos and mount them in a geared configuration to provide much more torque than a regular servo. However they still operate like a normal servo so you can connect them to your SSC board just like any other servo.

Not sure how much torque you need but there are some pretty hefty servos available.
The Hitec D845WP for example can be powered with up to 8 volts for 700 oz. of torque. Not cheap though, around $90.

I saw this on You Tube. It might have the answers you're looking for.

I 've done a little searching ,and there seems to be a lot of info on You Tube on this subject.

My previous comment about needing a pot mounted on the shaft was incorrect. You would not need that. However, you would need a sensor of some kind at one end of the travel or other (or both) so when you powered up your system the controller could determine a "starting point" that could be used to calculate all the other movements.
