I need to cut some .025 copper sheet and am looking for some suggested settings to begin with. I am using a Hypertherm 1000 and finecut consumables. The CNC table is a Torchmate 3. I've cut Aluminum, Stainless and steel but not copper. Certainly someone is cutting copper out there. This material is also much softer than anything that I've cut before. Any suggestions for supporting this sheet so it doesn't bend when the torch contacts it?
