The solution I am using is put G20 in RS274NGC_STARTUP_CODE of the original ini file. Then each time I startup, I select inch in view. Much easier than recomputing all the velocity and acceleration values.
On my other mill's I had always used Stepconf and selected Inches. This is the first time I've needed to change units. I still need to get all configuration parameters from the vendor, as I still have the ATC, Tool setter and Reneshaw probe to add into the system. This is based on a Mesa 5I25 7I76 interface.
