There have been many discussions here of possible ways to interface LinuxCNC
to real motors and such. I recently got an announcement of a new product
from the ClearPath people that may be of interest. For us$100 you get a
board with 120MHz ARM Cortex, Ethernet, USB, ESD protected I/O, H-bridge,
Measure from an arbitrary center to perimeter and calculate from three
points. Adjust and remeasure.

1) Measure the chuck hole-centres:
Measure 1 hole with a digital caliper. Zero the caliper at the full diameter.
Measure between the outsides of two holes. The offset zero will
I don't have "regular" tools for this. So I have to touch one edge.
Note the table position on the DRO. Then touch the other side and note the
position. Then finally move the table to the average of the two positions
and hope the DRO slides are accurate enough. Do all the moves from the
same
If you followed those instructions, the object remained a mesh of triangles
over the whole operation. But that's OK as the article was explaining STL
file mesh repair. The repair method is reasonable, they have you import
the STL, make a tiny change then re-export the part as STL and have faith
