Mach3 "Brains" was never really completed and was bug ridden. Art admitted that long ago. Classic Ladder actually works with the Modbus TCP and RTU interface! The "Ladder" part scares a lot of people, but being interpretive and interactive speeds the development process for a one-off application. I learned machine code, assembler, ladder, and then C etc in that order so I'm simply abnormal. ;-) Dave
