1st Build, Steel, Epoxy 24"x24" for Wood

Allow me to retract at least most of my last entry and apologize to our Asian friends. Oh...and admit to being a dope that goes off half-cocked...

I was looking at the edge along the base near the mounting surface - which is not really a reference surface, I don't believe. In checking the side of the rail where the balls ride, I get less than a thou over any 6-8 inches. At this point, I am just going to start on the gantry mounting and check it at different points as I go.

I think you will find some marking on the rail depicting the master/reference edge, once you have that set to your straight edge it would probably be better to use your gantry to align the second rail.

This is how I did it.
First rail as straight as possible then I mounted the gantry and slid it back and forwards as I was drilling.
Then I took it off and tapped all holes.
Then remounted for tightening the screws and worked as close to the gantry as possible :)

I have a feeling that that is also suggested in the Hiwin manual. Certainly worked for me!

I read the mycncuk diy manual. It's quite a read but lots of good pointers.
And the best part.. it got pictures! :D

I did read the manual but all the warnings about how accurate you need the mountings to be worried me so much that I closed the manual and just carried on anyway!
