No. I think we are on the same page. My code works exactly like in this video. In the picture above, the square rotates counterclockwise so at first I start from point A and go outwards towards point B and as I go past point B, I start to move inwards. This is why I have to subs in the code - O101 for the first and O102 for the second.
What's interesting is that in the end of the video they show the white plastic parts and their square looks pretty similar to mine - with corners rounded and flats not being flat but rather a bit concave in the middle (see attached photo. Not the best quality, but you can see what I mean). Only difference is that mine was twisted in the Z in addition to this (again see the picture). Then what's interesting is that on the next photo they show perfect polygons in metal which don't look like have been made on this machine.
