AndyUK's Build - 1.2x1.0m Gantry

[Clive S]

Andy Welcome to the forum and a merry Xmas.

You have certainly done some good research with the design. I use dual motors and home them independently with no problem.
The usual advise on here is to advise not to order any electronics (or kits of electronic)s as thing often change in the design. I don't think you will need the dual screws to be full length as you can move the nut mounting a bit further back on the gantry side and save about 200 mm of screw length.

I would also consider for the gantry HD ally profile say 90 x 45 two pieces one horizontal and the other on top vertical the slots in them are correct for BK12 bearing mount etc. so make it very simple.

Anyway just two sleeps for Xmas

Sorry to quote such an old post but isn't the hole spacing for BK12 46mm? Does it just work with the 45mm spacing on the extrusions? Definitely would save some work if so.
