![]() If you want to modify and distribute a Post to do that then please be prepared to support it. I am sorry but I cannot release a POST that I then have to support and maintain that is contrary to doing proper plasma cutting. If you did the pierces at one current setting and plunge rate versus the other it MIGHT help, but then again so does having control of the cut current dynamically and altering the pierce process in real time. What destroys consumables is piercing no matter when its done. ![]() Pre-piercing holes does nothing to increase consumable life or improve the cuts. "Once again this is forcing the plasma to do things that make little sense. Users report they double their consumables life on cutting 1/4" and thicker material." The concept is to get a more controlled pierce and prevent the consumable killing back splash. It automatically lowers the Z plunge rate too. On thicker material the BEST solution is to have the RS485 serial port on a Hypertherm and use the "Soft Pierce" option in SheetCAM (using our POST) and set a % of the full cut current to start the pierce. I have used all the way down to 16 ga without piercing completely through. For pecking drill spots we have the Peck pierce option that can be used to change the pierce characteristics and just make divots. The whole pierce process on thick metal is to prevent blowback that kills consumables. "I pointed out that the idea of pre-piercing is not a valid method of doing plasma cutting. ![]()
