We have cut corrugate metal, but the problem is that corrugated tin is so thin that it is hard for the THC to read a stable voltage because the material burns away so fast. If we bent up a corrugated panel from, say, 14 gauge, it would cut it no problem around 70-80 inches per minute.

Have you experimented with cutting corrugated sheets stacked together to increase thickness by chance?
Here’s a quick video showing the PRO cutting some 26 gauge corrugated steel. Getting a little bobbing in the flat areas simply because the Z speed had to be turned up high enough to get up and down the hills so there is a bit of hunting. I think we could have eliminated the bobbing had we increased the arc tolerance a little bit (this was cut with +/- 1.5 volts). Overall it worked fine and we could have easily cut parts out with these settings.
