I am trying to use the Motor Tuning to set the steps per XX and anytime I enter a value and click Save then Ok, I get an error with the options Y or N and Y keeps popping up the same error box and the only way out is to click N and then Mach3 closes. It is the latest version as of Aug 2019 and running on Windows 7. Has anyone seen this before or am I missing something. Apparently the config files are not editable / text so I am stuck using the program to try and set the steps for each axis.
