I am having a similar problem on the lathes. Generally I just edit the

generally have to play with the Z offset. That doesn't always result in
the backplot positions being a match when the actual cut does match.

Bold is not a font spec that is sent to the other end in a text mail, so
I've no clue what you are adding, or to which file.

A diff file, intended to be used by patch, might be a better way to
convey what you've done, and to which file it is done to. I am assuming
this patch is for ../lib/python/rs274/glcanon.py script, but since there
is not an absolute anchor point in that string, it could be located
anyplace in 75GB of data here.
If after those points are clarified, it fixes my lathe tooltable editing
shenanigans, I'll also be thankfull Tom.
