In Microvellum v67, I was able to create G-Code with 4 Character Numeric Filenames. It was in the Tool File Settings. I am now using Microvellum 2019. I am basically using the same Tool File and I have "4 Character Numeric Filenames" checked off in the Tool File settings. But the G-Code filenames are 8 characters long with numbers and letters. Also, I have also checked off "Create Sequential Files Names" in Machining Tab in Options. Am I missing something to create the 4 Character Numeric Filenames?
