Got my "Touch off to tool table" removed

Hello

As the title says..
So yesterday I was manually moving Z while not looking at the keyboard and somehow got the "touch to tool table" option to disappear..(I think)
I later noticed that the option was gone when I changed inserts and had to re-check the tool height. I haven't edited any files and I'm pretty sure it was working efter I upgraded to 2.7.3 but I could be wrong.

Is there some option I enabled/disabled when I was fingering around on the keyboard without looking?

Yea I know that but it still wont work I've also tried M61 with the same result..

This is the way I measure my tools (or used to)
1. In MDI, T(n) M6 G43
2. Touch off tool on a known height of the table.
3. Press "END"
4. Select "tool table" in the drop down menu
5. Done

But now the "tool table" option in the drop down menu is gone..

WOW! how did I miss that..
Would be awesome if someone could delete this thread and never speak of it again

Thanks a lot JT!

Well, I think it maybe has helped me.

I'm a relatively new LinuxCNC user and have made some nice stuff on my CNC Router so far. There's been a few funny things happen too some of which was related to how the origin was set at the design stage (my bad).

I've noticed that the Tool Touch Off button is greyed out when the G code file is first loaded but then appears after the play button is pressed then stopped or another part is made.
Maybe I'm doing it wrong?
My process is:
1. Home the machine Z, X and Y.
2. Touch off each axis (with tool in spindle) to the material with no offsets. Note, tool touch off is greyed out.
3. Then press play. I get prompted to add the correct tool and then off the machine goes.

If things go as planned all is good. If not, I stop the machine and touch off the tool to the top of the material and all is good.

Am I doing it right or missing the plot?

Cheers,
Jason.
