Starting from scratch (again) - Lathe gears

Thanks Andy, I'm storing all this info away for hopefully use as starting points. I think my situation is similar to what marius was talking about but he seems to have disappeared a few months ago so I can't ask.

I'm going to get something I can deal with on at least 2 gears, maybe just a high and low range for now and a chart on the wall.
Once that's done I can maybe sit and start learning a bit about how some of these various things work. I've got some (old) programing experience but this is all new pastures to me.
Seems like each time I think I've got something working I screw something else up
Included the RPM widget thing, Installed your macros and had them working, added in my USB pendant and now the RPM tab has blocked off half of the macro tab and it doesn't work again... probably need to change the order something loads but I'm just monkey-fisting my way around without really knowing what I'm doing...

Thanks again Andy, really appreciate the patience all of you guys have for us hobbyist wandering around in here
