New build with recycled parts on a ridiculous budget 120cm*60cm work area

proper linear rail will always win imo... 15mm is a slightly awkward size in some regards but more than strong enough for any loads your machine will impart.

"but more than strong enough for any loads your machine will impart." that's all I need to hear ;)

The big PITA is I need 4mm T nuts like 90 of them lol at £3.60 a pack of 10, gutted because I have a bucket of 6mm T nuts somewhere :(

But now I can do Hiwin for the z axis as well. So Real Hiwin's on the bottom axis and Z and clone Hiwin's on the gantry a significant upgrade from the original plan but need to seriously think about how to build this properly. I'm taking my time but I'm getting there and hopefully with a hell of a lot better than an xcarve/shapeoko at less than their cost ;)

Not sure what to do with the other 32 carriages and rail but when I get my machine working I might just turn them all into Z axis's to flog (Add 1605 ballscrew of course) or maybe make some extra large 3d printers to sell.

Be nice to turn the Hiwin's I don't use into cash but probably keep a spare set in case.
