If doing it again I would order 45x90 :)

Connected the profiles with t nuts in one extrusion. Then drilled through the other to be able to screw it together. Thought this would make a nice 90degree angle all by itself but I was misstaken! Have since loosened the bolts and retightened them while checking with a engineers square.. now I have a much better alignment!
Ofcourse the endplates help. Had them milled by a happy forummember with accurate hole placement for easy alignment.

Hope to get some free time soon to continue with the build ;) Christmas period has been hectic!!

Thanks for taking the time to reply, and thanks for a great build.
Do you have space behind the ball screw, to put a L-bracket instead? Like in this Photoshoped photo?

That's not necessary with the construction that is shown as the two profiles will be bolted together as have been mentioned by drilling the top profile in three places and fixing with tee nuts to the bottom profile

Had to do something today before work :D

What do you guys think about this?

Proximity for home, feelin the rail.
Mechanical switch for limit..

Good?

You know what, that might work but I think you would need a plate to join the fronts as well.. otherwise it might fold backwards?

Nice! Where did you get your proximity switches? Do they work with non-ferrous metal too?

Thank you!

Got them from ebay, 5 for almost nothing :)
Not sure I got the right ones (npn,pnp) but hey.. will go with what I have for now..

Dont think they detect non-ferrous.. can try tomorrow if you want?

Inductive sensors will detect aluminum but detection distance is roughly 1/2 they use them in 3d printers all the time for auto levelling the print bed.
