I realize it could be worthy to dig up that old post, with the updated manual. What a pain it must have been at the very beginning to get started with the machine, glad we now have a whole legion of members with machine AND some knowledge out it :-)

that's correct, this setting is a dedicated TR offset, separated from the part specfic offset (that are defined in the part definition itself). As a matter of fact, as explained in the alternative manual, the lack of vision depth of the side camera (flying vision) will induce an angle error with most parts bigger than a 1206 SMD. Plus the SOT have rounded edges and eventually the lead making hard to find the proper edge. Still, to avoid defining the part offset angle for ALL TR-like parts and ALL angles (0-90-180-270) in the part definition, there's a global setting to correct this, with system constant k6 #5. It's in motor steps = 1/100 deg.
Mine is currently -80 and works fine for both SOT23-3 and -5
More details in the calibration section of the manual from page 150. Remember that those offset should be trimmed / tune once the machine has been fully calibrated, otherwise it's a waste of time.

The led is an interesting example. Check page 45 of the manual, the led is used as an example of use of the W and Pt in the part definition. W is used there (with flying vision Lv=1) to offset the horizontal reference axis and align it with the opaque LED sole, this way the part can be checked !
