I've got a friend who makes carbon disc wheels for bicycles.
He uses one to check if the rim is perfectly round and flat.

Will do. It makes me wish I had a nice granite surface plate, and height

The limit switches yes but emc provides offsets after home.

Hi Gary
The limits are at the end of travel. As are the home switches. On most
commercial machines like this there are 2-3 or 4 switches on each end of
travel. What we do is home to the switches at one end and then offset
to the center of the table. This offset is set in the ini file as a

Hello,
Being new to g-code and cnc I've been trying to learn the best way to

the coordinate spaces and offsets etc (for a cnc mill).
I'm thinking I should use a *fixture* plate with alignment pins etc to
