In addition to what Peter said, it is unlikely that adding encoder feedback to Linuxcnc will improve their accuracy or error tolerance. Most decent quality servo drives do as good or better with encoder error detection than Linuxcnc. So if their servo drive is missing or picking up false encod

Hello! I am trying to help a guy to sort out config changes for their LinuxCNC machine. Currently they are running servo motors with step/dir signals and there is no position feedback to LinuxCNC. They are having some issues with machining errors and they want to change the config so that encoder
