What drivers have you got?

Im a cheap bastard (probably on the stupid side)
Got myself som 2dm860 chinastyle drivers..
They accept 80vac or 110vdc

Will se how they work ;)

Whatever works for you I was going to use an arduino and polou drivers originally glad I didn't lol. But they were cheap so I might well use them for laser cutter.

Given the price of a PP BOB the arduino really doesn't make sense and it's actually more expensive assuming you can get a PC for free for this task which I'm sure most of us can.

Just re-read the whole thread and I may have missed it again, but did not see how do you connect the two extrusions to each other? What is their size BTW?

I used 40x80 extrusion, most recommend 45x90 but this size was more availible for me.
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

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?
