That not quite true. We implemented adaptive-feedrate override some time ago. Initially it was thought to be used for electro erosion machines, but it can be used for anything. It's a float pin going into the motion controller with a value range of 0..1. If it's set at 1 emc2 will move at regular reedrate (program feedrate multiplied by feedrate override, clamped to machine limits). If it's less then 1, feedrate will be scaled accordingly. > implemented OUTSIDE of most of EMC, with a small HAL component that > would watch following error and use the halui interface to change the > feedrate override. That is a bad idea, as halui is not realtime. By the time it notices the input and sends a command to adjust feedrate override, many moons may have passed. Using a component to watch ferror and use that to control motion.adaptive-feed is the way to go.
