I think that is due to our configuration of the device, some setting we need to change somewhere.

On a side note has anyone ever plasma-cut aluminum? We were planning on doing it sometime this week and could use some pointers.

Here is our frisbee-launcher being cut this year http://www.youtube.com/watch?v=RUpf_stUnaw

Yep, we do a lot of stuff out of aluminum.

Not sure what system you have, and there are a lot of variables at play here, but what we've found is that it's better to run slower feed rates than suggested by the manufacturer, as this leads to less beveled edges. This will cause more dross buildup, so you will have to do some sanding/filing afterward.

Feel free to ask if you have any questions.
