Yes, in English it is called shimming you could use tin foil or you can buy shim of various thickness

Nice, I will take a look at it.

Ok well straight away I see Chicken and Egg problem.! How do you access the linear bearing bolts under the gantry.? If fasten the plate to bearings first then how do you bolt profile to the plate.? Also how do access bearing bolts when squaring setting up etc.?

A much better way is to have 2 plates. One that fastens to the linear bearings which also incorporates the X-axis ball nut mounting plate. Then another bolted to the gantry which then bolts into the bearing plate.
This method makes it a lot easier to setup and square the gantry etc. Also can remove the gantry in one piece if ever need to move the machine and not loose setup.

These pictures show what I mean although it's set up for R&P.

I didn't see that to be honest. Good point, I'll add a plate, thanks you JAZZ :)

Great post Jazz - there are some things we miss out on in our original designs like how to mount the stepper motor cable chain? or how to adjust the spindle position for tramming? - both mistakes I made in my design and build!

I'll add it too, thanks :)
