I think I found a limit switch, not sure, hopefully I can get some pics on here soon. One thing I noticed is when in manual there are various options for homing but in auto there are only two, no idea why.

Another thing I tried is to get a simple wizard to do something (a groove) but no result. It's so confusing and I can't find documentation for all the little things it tells me is happening. If I could just get a wizard to make one move it would be fantastic.
