Low budget plasma setup, what do I need?

i got also a low cost setup
1300x1300mm the Z is 60mm as you sugest already

what is your budget

I will design mine to take 1000x500 material size.

Plan is to have a stand with water-pan outside and the CNC frame is to be lifted in place to register on the stand.

Budget is very low, I have the material for the CNC frame that will be 80x40 Bosch alu extrusions. Linear rails I already have Bosh R1651. Not decided yet how to drive my X/Y but probably timing-belt as the frame needs to be kind of rugged with minimal manhandling problems during storage.
I have to purchase the material for the stand.

I think 60mm would be OK. I started with a 150mm ball screw and by the time its was built travel is a maximum of 84mm and a lot of that (10-15mm) is currently below the slats based on where I have clamped off the torch.

That is usable for sure. If you intend to use floating head ( highly recommended ), make it so it has as little travel to trip the switch as possible.

OK I hear what you say Tommy.

So I need to shout out to PCW for some help to add code for 7i37 (P2 or P3) as I will need inputs to get a floating head switch working.

Done some sketching on the floating head.



The beige part is on IKO Crossed roller way unit (overkill yes, but I have it laying around)
Unfortunately I have not found a 3D CAD for this part.

i got also a 4axis running at this low cost profiles Bosch type with homemade screw fittings
this is 1m x 80cm x 160mm Driveway

try to get your plasma as shielded as you can against envirerment
EMI is terrible to fix after build



Video of function is here

Here a preliminary draft of my CNC table (no stand)

One rail on each axis, linear rails, mind you. Nice!
That should work nicely for that size.

im not going with toms suggestion one rail at a 800mm Span
you need to go double rail even if you use SBR12 better then leave it with dirt running on aluminium

and on that size it is a posible middle Ballscrew drive
as special as he gots very stiff framing

he also planing to use a water plate you need no more then 2inches of water table hight pool seeling clue is enoff to hold the metal together
at that length and width hight

if you use L-profile it will give you even more stiffness
