Sample config w/tool length

Running 2.8.4 and was looking to integrate tool length probing.  I think its the last thing i want to add to my setup, so thats exciting!

Looking through the forums, it seems there should be available a sample ini thatll work for a cnc router that also includes the tool length measurement operation.  I could not find anything that is shown as such in the list of ini's at startup.  Does that mean I can only integrate the procedure by manually inserting some coding in my ini file?

Is there not a tab option in pncconf that sets parameters for tool length measurements?
 

I don't think there is a built-in probe method in axis or the other 2.8 docs.
I would consider upgrading to 2.9 and look at the probing in qtdragon
linuxcnc.org/docs/2.9/html/gui/qtdragon....uto_tool_measurement

I just published a 2.9 version of the Linuxcnc live installer that would let you run from a USB stick to see if it might work for you.

I couldn't find it in the docs either, but I stumbled on a LCNC forum thread (in my search to be able to measure tool length) where it was recommended to another user to load a sample INI that already incorporated the tool length and then start configuring from there. Of course I can't find that thread now, but I'll keep digging. I'm pretty sure it was a couple years old so I wouldn't think it was referencing 2.9.

I suppose trying the 2.9 version would be my next step. Is it relatively seamless to transfer my current set up to 2.9? My only experience with LCNC is with the 2.8.4 Debian installer that I used on an older HP ThinClient. Has worked great so far with the Mesa 7i96s and my CNC router. I dont want to take any steps backward by attempting a new install (if it works via USB live).

Here is what I saw:
forum.linuxcnc.org/49-basic-configuratio...ol-measurement#78003


Does this apply to what I am wanting?

It's probably best to assume I dont know anything about writing code or programming, so if doing that is needed with my current version, I will attempt updating to 2.9.

Is there a way to update to 2.9 without reinstalling the OS and without having the pc connected the web?

There will be a way. What distribution are you using? Is it Buster that is used by the official linuxcnc .ISO?
If so I think it can be done by changing your apt sources and change it in Synaptic. I have not done it for years so I'm not the one to guide you here.

Yes, I believe so.

I downloaded the ISO labeled: LinuxCNC 2.8.4 Debian 10 Buster PREEMPT-RT ISO

Copied that to a bootable USB drive and did a clean install on the ThinClient PC.

I have the Mesa connected via ethernet, and I could never get Linux to recognize or enable the wifi on the PC. So any updates or software changes have to be done by some other means (not sure exactly how that works just yet).
I had originally intended to get everything implemented and stable, then leave it as-is. The last piece of this puzzle so far is the tool measuring.

So if it requires a full re-install of the OS as well as 2.9, I guess that's what I need to do, but I haven't found a bootable 2.9 installer, which ill need since i have no connectivity to the internet.
