Hi, Jim Neifert
1. nothing wrong with what your do-ing
Some of us are having problem's with the auto file name function, it saves the file in Mach3\gcodefilename.tat it should be
Mach3\gcode\filename.tap.
Turn off auto-filename in LC post options , Save the file under Mach3\gcode\yourfilename.
2. I have not used these features much re-run the video.
3 Shut's down the window don't think there is a way to turn it back on yet.
Hope this Helps, Chip
