Kelly the Carver's Portable LR3 Build Thread - Ice Edition

Squaring question.

I missed the mail carrier today so will pick up my bits and bobbles tomorrow but in the meantime have been finishing getting the machine ready for the freezer.

I found this post and YouTube video and it all made sense to me but when I made my measurements I was off by a pretty good deal - 18mm or so. I tried the “easy way” in the configs but once I got over 12mm of pulloff for Y2 things didn’t look so good on the machine. I guess I better do this the proper way. Question is, what is the proper way? Is it the rail that needs to be squared up better?
