Aluminium profile CNC

[JAZZCNC]

I just find time to update my design and change several thing. I hope I take into account every advice.
If you see anything wrong please let me know. Thanks.

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.
