I made some progress today with cutting fine detail. I'm new to cnc plasma, so I just expected to be able to cut anything just off of book specs. I quickly found out that you had to slow down with thin metal and and small detail. After several emails with Dan at LDR and some help from Jim Colt I finally made a cut which I think is pretty good for plasma.
This is 14 gauge cut at 95 ipm at 40 amps with finecut consumables. The square is 3" x 3".
I have a little bit of dross on the back, but nothing major. I thought about applying some path rules to slow down the tight curves a bit. I do see some wiggle there. Being new to plasma I don't know how much accuracy that I should expect. How does this look? Any room for improvement?
I think it is looking pretty good! Very nice. It does look like there is a tiny bit of wiggle that you should be able to get out. I would double check everything and make sure it is tight and there is zero play between your torch/gantry/table/slats. The inside cut looks very clean.
I like it. It only gets better from here.

Usually, putting a curve in the slats will keep them tight. My table has straight slats and I get slat wobble when cutting at high speeds. To stop it, I lay large drops across the areas that aren't getting cut and sometimes have to clamp them down to each other. I am too cheap to purchase new slats, especially when I have a few more months worth of cutting before they start to get ugly. Once I do replace them, they will be cut a little long so I can bend them and drop them into place, putting a bind on them and that should eliminate the slat-wobble.

Thanks for the info. My table is fairly new with curved slats. I had a half cut out 5' x 10' sheet on the table. I'll check for movement next time that I cut.
It only gets better from here.
