Re 2nd Question...
The arm and its motor do not know whether you're asking it to go inside out or outside in. The same mechanism does both, so if one direction is working the other should also.
When starting at the label:
a) ensure the arm is on the back side of the spindle - that is, the other side of the spindle from you, at the front.
b) the arm motor switch is in the on position. (This sounds silly obvious, but there have been moments when I position the arm and stare at it for a few moments before realizing I need to flip its motor switch.)
Re 1st Question: take a look at this PDF file
Fwiw, there are several good threads (nopun) here with Loricraft tips. Great machine!
