I will look into the .nc now.
I don’t have a Ridgid but there are a couple of posts about that orange thing and upgrade exaples here in the forum. The fastes way to find things in the forum is to copy this from the browser you are just using → forums.maslowcnc.com then open a new tab ond go to giggle or duckduckgo and paste that. Adding a ‘blank’ and ‘z-axis’ and then switching to pictures. I got pretty fast 
Once I see the piture I like I’m in the forum post discussing and asking.
1 link I found Cheap fixes for z-axis slop on the Ridgid R22002
