I just wanted to say I am so impressed with this feature it’s just spot on!! 
Thanks! That one was my idea. I built that to protect my spoilboard from MYSELF. 
honestly I didn’t know that! Keep them rolling Eric 
My previous machine seemed to love digging the spoilboard even without the feature
When do us old timers get it on our 2019 machines?
Anytime you want! You just need to upgrade to an EX system 
(we make it plug and play for you!)
New here - what does this feature do specifically?
Prevents you from sending a g code job that could cut into your spoilboard
It does appear that you have to turn this feature off if you need to resurface your spoilboard
Well not exactly let’s say I wanted to cut off a inch off the back of my spoil board and my spoil board is 2 in thick I would leave it on and enter 2 .01 in the field provided and shut down CNC12 and restart it then you should be good to go..
What I forgot to say was make sure you go back and reset your settings otherwise you could have a big mess
