As the guys pointed out early, there are several simpler solutions to implement the DRO functionality you're looking for. Nevertheless you can take a look here to see some source code to have a starting point to make your own components in case you need it: https://github.com/LinuxCNC/linuxcnc/tree/master/src/hal/components Some are pretty simple and understandable, others look like chinese to me LOL.
