Understanding these anti-dive settings is essential to plasma cutting operations with THC enabled. The "anti-dive" settings in Mach4 allow precise control over the exception cases which cause unwanted THC response. This unwanted response can result in the torch "Diving" to the workpiece. Mach4 Anti-Dive - Plasma cut quality is dramatically improved with the use of Torch Height Control, however there are scenarios which cause the torch height controller to respond improperly. Additionally, the exact response of the torch height controller to differences between actual and target tip voltage can be set in the TMC3in1 plugin controls within Mach4. Mach4 Torch Height Control - Ideally the target tip voltage will be set by the g-code generated with SheetCam, however the cut feedrate and target tip voltage can both be adjusted with override controls in Mach4 to "dial in" the cut quality at the machine. Geometry based settings to enable/disable Torch Height Control may also be exported as part of the g-code. SheetCam Toolpathing - When configured properly, SheetCam can produce g-code which represents the cut profile, speed of cut, target arc voltage (cut height with Torch Height Control), and other parameters required to execute a successful cut. In order to ensure a quality and successful cut, plasma users must have a good understanding of the following topics: Ensure you have selected Plasma as your cutting tool in the Avid CNC Machine Configuration menu.Īdditional guides (not required for plasma system setup): Mach4 Setup Guides - Skip this guide if you have already installed Mach4.Follow the guides listed below to setup and use your PRO CNC Plasma system: CNC plasma cutting is an excellent way to process sheet metal quickly and easily.
