This foam kind of turns to goo if you try too fast of a cutting speed.

about the power supply, i read the geckos wont give more than 67% of the current you select with the current set resistor, so i was thinking 12 amps could cut it. We havent found a power supply yet so were still open to options. Should we do the 16.5 amp + supply?

What about using a variac bridge rectifier and cap as a power supply? dial the voltage and be done with it.
