Building a chain driven Plasma table.

Attached are some photos.

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?

 

No drag shield.
Looks like to slow and a bit to high.
You will have to do a lot of test cuts to find out what works for you, so do straight 100mm cuts first while changing cut voltage (that is torch height) and feed rate (can be adjusted on screen while cutting), but first and foremost, use new consumables and make sure the air pressure is as specified in the manual while the torch air is on.
After you get clean cuts with little dross on straight lines, do some small squares and some small rounds, about 50 of each. If that all works OK without issues, cut some bigger logo or whatever you like.

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?
