Jim,
Some good things for me to try there. I cannot get fine cut for my Thermal Dynamics A60, not that I can find.
I did have too much power, and probably still do. I need to investigate the cut speed more, the software has a 'faster' and 'slower' option, but I'm sure it has more granular control if I read the manual. My torch is too high off the plate, it freaked me out when it started dragging a warped sheet around the table and grinding

so I lifted the head up a little, then the material warped more so I raised it again, then it warped more so I raised it again; each raise it height required more juice, can you see where I went with this one. Probably as high as a 1/4 inch and 60 amps

. I thought it affected cut quality (and for my test pieces I wasn't too worried about this), I did not know I was perpetuating my own misery by creating corrugated sheets out of perfectly good flat metal
I was approaching this as getting it cutting out shapes properly first, then fine tuning the quality later. It seems you need all pieces in place for this to work, if you miss one then all the rest go too.
