In this control you can switch in program from inch to mm and back to inch, with a g code and everything runs correctly. Including tool offsets and lengths.
do to the parts we make sizes and locations are in inches on the drawings but within a family of parts all the circular hole patterns are in mm, and that is all that will change in a groupe of parts, ie. same part , but the bolt circle dia. changes in mm. so this control works great as you do not need to convert to inches ,just insert g71 in the line of code. and in the next line a g70 and you back in inches.

Does anyone know if any other control can do this?

This A2100 is from 1999 , and has many other features we have grown to love, that our Haas does not have.
any help appreciated.
