Gantry Twist & Bed Mesh Issues on RatRig V-Core 4 500
Agree with the PEI plate comment, I had bad gantry twist with my provided RatRig 500 plate. I bought a plate from Lukes Laboratory and without any changes, my gantry twist was fixed. I also found that just by adjusting the feet, I could adjust the bed mesh.

VOAC calculating offset wrong by the same amount every time
I had a similar issue where my Y was good for the IDEX and my X was off. I did the IDEX calibration test at all 4 corners of my 500 as well as the center and it was noticeably tracking worse farther away from teh VAOC. In my case, it ended up being that I had my X-axis belt tensioners adjusted differently (trying to get the IS graphs the same). Once I adjusted the belt tensioners to the same length (and have exact same belt lengths as suggested)

Cant bring up the left back corner
Having said that, I'm still battling first layer issues when using the full printer bed space. Gonna order one of the Toro titanium tubes.

Cant bring up the left back corner
Have you tried adjusting the printer feet? I was able to at least level out the corners on mine by adjusting the mounting feet. Didn't resolve the bed/gantry warp at temperature, but improved the twist anyhow. I also saw some improvement swapping to another PEI build plate, improved my gantry twist as well.

Regular surface distortion pattern towards end of larger first layers VC4
You aren't alone, I have also been having first layer issues and figure it's got to be because I am a novice coming from a Bambu. I don't have words of wisdom here since I am still battling the same fight as well, but will be listening to see if some of the smart folks on here can help. I do have high gantry twist at 130 micrometers that may be my issue. I also have struggled with getting a good bed mesh with it cold around .280 on a vc4 500. Will stay tuned to see what helpful advice comes your way.

Just fyi for those that have the same issue, I ended up flashing a new SD card and reloading into the raspberry pi and going through updates again.
