A CNC newbie question: Why can't the serial output from a Sargon
or similar DRO be fed to a computer then used to control a servo motor on a vertical mill?
What serial output? Most DROs don't have a serial output.
But, the real reason is most DROs update about 2-5 times a second. That would allow you to
move about 1 inch per hour with confidence. I run EMC at 1000 updates a second, and a
lot of newer CNC controls read position 40,000 to 100,000 times a second for smoothness
of motion.
