This is more for my own curiosity than for any deficiencies with the cutter. Really nothing to solve, was just curious about the regmark size.
If I actually told you how far off it is, I think most folks on here would start with a blank look and then a smack upside the head.... It's well within tolerances, which are pretty tight if you look at the specs.
I've probably just gotten a little lazy with how far apart I'm placing the regmarks, and need to tighten them up again. Put this one down to Operator Error.
