Dang! just picked up a length of 7.5 metres 25x25x3mm mild steel box section to start me CNC build.
It was £25.66 in VAT($40.91) thats a hefty price just for one length and I probably need another 3.5metres? to complete the gantry.
I suppose really its cheaper than going the Aluminium route so I must not complain too much.
Bed size is...
750mm x 600mm x 350mm
I'll be housing the Motherboard(PC) and all electronics within the bed frame below the bed so that alls I need to connect up is a monitor&Keyboard to the CNC
