VC4 500 IDEX terrible bed mesh
So my mesh looks absolutely terrible, 0.428mm deviance min to max, does this look like bent gantries?

Technically 0.5mm is within spec. But, you could get it under 0.2mm if you try. Try going through this video. It got me under 0.2mm.
Trust me when I say though, your printer is going to “settle in” a little bit. So whatever starting mesh you can get will go right out the window after a certain amount of prints. For instance, I had 0.196mm on my 500 then ran a 19 hour print with ASA. After that print, my mesh was somewhere around 0.45mm.
I’d go through this video but not worry about it too much. I spent a stupid amount of time chasing perfection. Plus your mesh is gonna look different when you heat everything up. The gantry bows downwards. So, technically your current mesh would get compensated at a certain temperature.

It is possible that your X-beam is not straight or will bend due to the different thermal expansion of aluminium and steel (rail).
You can check this by heating the printer and doing a bed mesh every ~10 minutes. You can save them with different names so you can easily compare them later.
