welding steel base or just getting aluminium extrusion

I look after a machine that is built similar to option 2 built by a company with initials like MD and it does work and cuts 8x4 sheets of 6mm MDF all day.

the rack & pinion seems to be fine and the rack is mounted inside the slot on the side of the top rail.

Have you thought how you are going to drive it and what motors etc.

yeah i already have 90% of the electronics planned out with the help from Dean using high quality ballscrews/hiwin rails/rotating ballnuts for the long y axis. even though i said i was going to copy of cncrouter.com that was just for the bed but everything else will be better and defiantly will be wanting to cut thicker then 6mm all day lol :)
