Nah I say "Do as you like not what I say" . . Lol

Ok well I see one thing that needs changing.? Don't fasten the bed to sides by pulling on the sides. Make it so they Clamp like this.


This machine will have a 4th axis on the short end that over hangs, 150mm of overhang. The large overhang is to keep frame floor footprint down and saves wasted frame material.
Won't be using single motor belt drive as person who it's for wants to use large long material and the bar could be a problem. It will however use 20mm pitch screws with a 2:1 ratio to keep screw speeds down and reducing chances of whip while still maintaining same feeds as 10mm pitch. Will also get a bit extra torque.! Screw will also have BK Fixed end bearings at each end and be slight preloaded.
