Building a chain driven Plasma table.

   

I

So I made my first cuts. 
Made some 30mm holes in some square tubing. See photo. Is this what you can get from plasma or can plasma cutting do a better job? 

I use a Hyperterm Xp 45 powermax. 
With a hand torch and a drag shield will quality improve if I use a shield that is made for a machine torch?

 

Thanks.
I just used conversational in qtplasmac.
I tried to increase cutting speed.
But it always cuts the same slow speed.

I downloaded sheetcam unfortunately it already asks for a
License key.

Is there any free software to generate G code for plasma?

Thanks for the info.
I already have Inkscape on my computer..
Did not know it works for generating code for plasma.
I have tried it without success .
After some searches on the internet I found some tutorials to create Gcode for routers.

Where can I find some tutorial for generating Gcode for plasma?

So now I have another question.
I still have to make a water table.
The machines Frame is 1.8 x is 3.3 meters.

I am planning to put a rotational axle for round pipes. Max diameter for pipes about 250mm

Maximum sheet size I am planning is 1250 mm x 2450 mm.

How big would you make the water table.
Is there a benifit of making it larger than the Methal you cut? I am thinking about splashing etc.

What material thickness do you guys use for the water tray? What thickness for the slats?

Thanks I Watched the video but it looks Ilike it doesn’t create the correct size.

Length I put on Inkscape is 300 mm
Length on simulation of geode is 346mm

Is there something I did wrong?

You can try this:
github.com/multigcs/viaconstructor

never tested with plasma , but if you tell me if there is something missing, i will add it.
