Jean-Claude, were you ever able to make any further progress with your changes to the UHU.HIGHPOWER drive. H.O. has a new chip & module that increases the speed at which the drive can process & thereby control the rapid travis & feeds. it has firmware that allows some lead & following error between the machine & program (which is adjustable) which to me would facilitate some fast roughing at minimum. not a very good description on my part, but go look at his thread "Servo processor "upgrade module" - looking for volonteers."
