Retrofit cnc plasma help needed desperately

Hi everybody.
I am new here, how ever this forum is not new to me.
I have a cnc plasma machine with was retrofited 9 years ago. The supplier went bankrupt in 2018 and I was looking into linux cnc ever since. (but not brave enough to install it and experimenting....)
The original machine was a Messer Griesheim Cortina S 2600, the retrofit included the servo, main computer, ac motors and gears, a IHT height control and a Kjellberk High Focus 160i.
Now a small software problem throws this machine out of service and I am looking for a solution.
Who can help me to install and configurate linux cnc on this machine. Is there any service or did anybody know who can do that remotely, I am very happy to pay for the time and effort.
I am not sure whether It is appropriate to offer money on this forum but I am very desperate.
 

Thank you so much for your prompt reply. Great project indeed.
You have still the DC motors which I replaced on my machine already. I will take pics tomorrow and post them here. The hard ware from the 1. retrofit is still like brand new, the target will be to use much of it.

Ok busy day today here are some basic pictures.We also found a way to twist the damaged software and we are able to cut how ever with more time and effort. But the pressure is now off and I can spend much more time to go through the linux cnc soft ware. Again the machine went through a retrofit in 2016 hence the hardware should be not complete outdated.
1. Which version of linux cnc should I download. Please advice a complete package including the OS and Kernel.
2. I want to install it along the windows 7 as some configuration files from the old cnc control might be needed. Is that possible?
3. Do you think any of the existing hard ware could be used by linux cnc? 

The 2.9.2 ISO on the downloads page includes everything you need. A few people have retofitted similar sized machines with QTplasmac.
It is possible to install linux onto an existing windows HDD and you can access the windows drive from Linux and select the OS from the GRUB boot menu.
I had a PC set up like ths until I did something silly and broke Windows Totally.
I have two Dual boot PC's with seperate drives for Linux and Windows which I boot from the BIOS boot menu. No sharing. One of the Windows partitions broke. The other one is still OK. I use Linux for everything now.

Another alternative might be to use seperate PC's and map shares across the network using SAMBA. This works nicely for file sharing... but not trivial to set up (Although Win7 should be easier than Win 10/11 which disabled some required policies)

@ rodw. Thank you I will do it asap. And yes I also use Linux since 2009. Such a relief. 2 Lap top dual boot. I am definitely not a computer geek but the change was worth the effort. Deskt. Mint una XFCE lean easy great.
@ Acira yes indeed I attached the SDI Interface manual. (Copy rights should not be a problem the company does not exist anymore) As I understood there is a plug with analog inputs. But I also would agree to change the servo as I don t know where I get it fixed or get a replacement. Which servos you would recomend?
 

I took a Quick Look a the “manual”. It has no info about what the analog inputs can be used for, a vague mention about some (probably proprietary) bus system and no mentions about how to set any parameters.

I would probably scrap the idea of using the existing motors and just replace them. I might be wrong but that manual does not really help at all.

Went through some of the details in your Messer Project and as far as I understood is that pretty much non of my existing equipment is usable.
Question
You used the old dc motors but you changed the encoder is that right? I have still the old dc motors. If I could understand which encoder and how to fit it onto the old dc motors I would have the same situation as you - Gecko dc servo drive Mesa card, and Z drive ...we will see. Could you please comment that.
