Help with Lichuan drives

Hello forum,
I have 6 x 1KW Lichuan LC20 drives and have been trying to get them to work with Raspberry Pi 4B 4GB and LinuxCNC for about 9 months.  I realised I don't have the technical knowhow to make this work.  Using this forum, youtube and Grok, I was able to get close, getting the Raspberry Pi to work as a master and I even got all 6 drives to work as slaves, but trying to get them in to OP mode proved impossible.  On one occasion, when I unplugged 5 of the 6 drives, I managed to get it to go into OP mode but have not been able to replicate it since.  And I have never been able to understand how to get them to turn using LinuxCNC, that baffles me a bit so I have never actually seen the motors work ever.
I am open to buying hardware that kinda works out of the box but I have no idea what that is.  
Can anybody on this forum work with me over time to help me to get these things to work with LinuxCNC, or even Mach???  I can't return them, and after spending $2K on them, I can't afford to buy something a little more 'out of the box'.
Any assistance would be greatly appreciated.
Andrew.
 

Don't know where to start.
Here is an example of setup of a cia402 drive, your servo drive is a cia402 drive.
This is a starting point. Change vid and pid and this might work right away.

First, show us what you’ve got and where you’re at. Your XML and ini files. If you’ve got any errors, include the dmesg output as well.I’m sure we can help you

You can try these examples that I have working with some of those ETHERCAT servos

You guys are great, thanks. I will try your suggestions and will then put together all the files you asked for etc.
Thanks very much.
