Hi All

I am new here, I am trying  the mach4 function, when I use bolt hole wizard, I only can save and load the file one time if I use a same file name, but the wizard works well if I use different file name each time after I change setting , the mach4 is demo version, someone know how to be able to use the same file name? thanks.

Hi I find out the problem that I have to close the file first and to use it again.
