Mach4 Toolbox / Re: When changing from mm to inch unit
« on: June 18, 2022, 10:13:54 AM »
To work in alternate inch and metric systems, you do not need to change the configuration of Mach itself.
Indeed the configuration setting only affects how the steps per unit parameter in the configuration is understood by Mach while doing the initial axis configuration.
To work in alternate measurement systems you should insert a G20 command in your-G code file to tell Mach to treat dimensions as inches, or insert a G21 command in your G-code file to tell Mach to treat dimensions as millimeters.
Mach does have a group of startup settings to select the default mode. It sounds like your default is millimeters. The startup settings are one line of G-code that is automatically run before starting any job.
