Kerf of .050 (lists .051 for 10ga, .049 for 14ga).
45A, .4 pierce delay, 107 ipm (95 for 10ga, 120 for 12 ga), 84 volts.
My first part, I was not happy with. Corners were serrated and rough, lots of tough dross, and I had to beat/pry the part out of the sheet. It didn't appear to have cut completely through. I am using a water table, and had the water about 1/2" below the part, so that my be the issue with the bottom dross/lack of cut. I understand the volts may need to be upped when using a water table. I need to grab some feeler gauges, so I can see where the tip is actually at for 84v.

I think I had the holes rule in place (as created by Matt at Bulltear, I assume), but I don't remember for sure.
For the next several cuts, I played with rules, but kept the kerf, amps, pierce delay, ipm, voltage etc the same. This is the last piece I cut. It was running holes, small parts, inside corner, outside corner, small circles, and arcs rules. All rules killed DTHC just before the feature (I think it was .10, but I don't remember for sure). I can verify the rules were working, as I saw the different colors in Sheetcam (as well as start/stop 'x' marks), and I also watched the screen during the cut. I could watch the feedrate drop down to 60% (my rule value), as well as the DTHC light turn on/off, and voltage climb above 84 when light was off. So, it seemed to be putting the rules into play.
I can't really say I noticed a difference in cut quality, though. This is the last part I cut.

Parts were grounded through slats. Table assembly is not grounded to earth (working on that, see my other thread).
To you experienced guys, I'm just wondering if these photos "scream" anything out to you. In the meantime, I'm going to put in the regular 45A components, and try the part with the 45A stuff. I cut a couple of small brackets using 45A, and the edge quality and cut geometry looked much better to me than the fine cut stuff.
