total rebuild after theft

I am having to totally rebuild my pc after someone broke in and stole the pc from my CNC router. Apparently they didn't realize what the machine was and just took the pc and all my thumbdrives, external drives and discs.
I built this thing on EMC2 with Ubuntu 10.?? and all my backups were on the external drive and 2 of the thumbdrives.
It has worked so well I haven't had to tweak anything for many years now. All of the memories of getting it configured are gone with hundreds if not thousands of toolpaths stored on it.
I have built a new pc and have the LinuxCNC 2.7.11 up and running. Now I'm struggling to remember how to configure everything.

Here's my setup:
4 KL4030 drive
4 KL23H286-20-8B steppers
C10 Break out
Gantry with Rack & Pinion on XLeft and XRight, Rack & Pinion on Y
Z axis is lead screw

I can't remember how I set up the two R&P for X. I have them labeled on the drives as XR and XL
Can somebody get me rolling again. I have read all the documents and they are clear as mud.

I'm thinking an example config might jog my memory.
I've run the latency test

I just found my original info on a post I made 6 years ago.
It has my hal file and my configuration.

I'm trying to apply that to my new install

any advice?

is it possible to convert the old hal file to the new version?

Yes it is possible to convert the old files to the latest current version. It is best to check the upgrade information in the documentation for each version between the one you used and the current one for the applicable necessary changes to your files.

If you really want to run the old versions, it is also possible to download the old Linuxcnc and EMC2 iso files from here.
