Hi all. I have a DynaCNC table with a Hypertherm 1250 torch and Mach 3. Much of what I will do will be cut out of aluminum in the 3/16 to 1/4" range. Hypertherm's cut charts are pretty good for steel but not so good for aluminum. Any tips from anyone out there on minimizing blowback, voltages, ipm, etc. for aluminum vs. steel?
