New Build-12x6ft Plasma Table

[Davek0974]

Yes I was thinking of an adjustable 'Z axis', the diagram of the table was only a rough idea.

If by adjustable, you mean a torch height control, then I would say for a build of your size it would be essential, not just a thought ;)

My biggest problem of the whole build is the motors and the rails setup. The fabrication of the table and the separate supports for the gantry is the reasonably easy part?

One thing I have learnt so far is to take it all into consideration, but build it in parts.

Do I have to buy the rails as a one piece or can they be joined?? Also how many do I need??

Liner rail like HiWin can be butt-joined if carefully aligned, longest bit in one length I think is 3m. As to how many, if you take a look at the specs, they can take a massive load, the 15mm section am looking at can roll a 1500kg load! It must be fitted correctly though with side support etc.

This lad used angle irons and rollers like a roller gate set up for the liner rails will this system work?? is it a cheaper method??

Cheaper, yes, better, no.

I would look at proper linear rails, one per side probably 25mm size, but thats just a guess. Get the carriages fitted with wipers and scrapers.
