My machine is Metric and I have Mach4 is set to MM. Mach and the machine run both metric and inch programes without any problems (so far).

However the only niggle I have, is with the MM/IN indicators in the Axis DRO display.

When running an Inch program and any axis display is stationary, then the indicator displays "in" correctly, but as soon as an axis starrts to move, only that axis indicator flashes from "mm" to "in" rapidly, the stationary DROs remain correctly at "in".

The actual DROs continue to read correctly in "Inch" when this is happening.

Running Mach4, Build 3804
