"No tool measurement! Please take care of the entry in the tool table."

Hello,
I'm trying to set up tool measurement probing, and I'm certain I'm just doing something dumb and don't know enough to google the right thing. I have followed all the setup steps in the documentation, and everything seems to work fine. When I try to do a tool change now, though, I get the error message in the post title.

I have never used the tool table before now, but I tried adding entries in all of the available boxes (tool number, slot number, x, y, z, diameter, and notes) and I continue to receive the error. What am I missing?

I followed what is listed here: www.linuxcnc.org/docs/html/gui/gmoccapy....uto-tool-measurement

I do see all the hal pins from section 4.2.6.1 in the hal meter. All of those pins seem to not be defined though, as they are all 0 or false even when trying to do a tool change. Is there some setting I am missing that will enable all of the pins?

I am using 2.8.1. Would it be helpful for me to upload a zip of my config? I feel like it must be some very stupid small thing I have missed in doing the setup (although I have gone over the instructions very carefully more than once at this point).

Here are the files. I realized that I was mistaken, I'm actually on 2.8.0 not 2.8.1.
