plasma advise sought, want to make a a3-a2 sized machine

just a little one for making brackets and the like.
want to cut at least 5mm steel plate.
can you point me in the duirection of a plasma cutter.

is it possible to have no movement in the z axis, simply setting the machine for 5mm plate
adding 1mm under grate for 4 -etc.

I realise I don't need heavy duty motors?

do i need to have the ball screws to the sides?

is it wise to invest in rtwo sided belt drives for the x axis

whaere do you get them

do you use a floor grate as the sacrificial doofer?

Hi

have a scan through this forum and check all the threads by me - Davek0974

I recently built a small machine and you will likely find 90% of your answers in the threads somewhere, pictures too.
