Supply houses put on training classes on this type of stuff all the time, normally given by a manufacturer's rep. Most often, these classes (workshops, really) are free. I recently went to an all day class for a particular brand of motion controller, and it was at a supply house that mostly deals in bearings and belts. Go figure. Went to a really nice VFD class at a shop that sells and rewinds motors. Gotta keep your eyes peeled.
One reason not to give DIY advice:
Catch a man a fish and you can sell it to him.
Teach a man to fish and you’ve ruined a good business opportunity.
