I'm comfortable coding etc so I'll have a look around first before asking for specific assistance - just knowing that I need to edit the post proc file is the hint I need.
I also need to modify the 2017 screenset to include the homing offsets - although I can manually put the parameters into the profile config, and they are loaded and used fine, the screenset overwrites them with zeros when I save it again...
I guess it's time to break out notepad++
