Got some more work done yesterday evening. Started measuring out the rails and fixed them to the back-plate. All nicely aligned, not too much of problems.
still need to drill and tap 20 more screws to secure the rails. When all is done and working, I guess the Z-axis construction will have about 80 screws in total.
Also once more took off the lower rail and finalised for now on the spacers, it's as straight as I could wish for I think.. Let's see if that holds true when the motors are driving it all.
Rails done with 4 screws for now.
Front plate on.. It's heavy, but moves as smooth as you can imagine..
Side-view. Blocks used as spacers to create space for the ball-screw.
Now it's waiting for the screws and drilling many more holes and tapping them.
Cheers,
Luc
