How do I set the speed of the z movement when the torch plunges for stock.

I have been having issues with certain settings under sheet cam. I have drawn a simple square and applied the thc300 post processor to it. To save users of the Pritec ACROS Plasma CNC the time on making their own post processor work for their machine, there's already a post processor ready to go for the machine! There's also an accompying blog post to help you get on your way to effortless Gcode generation.I am a newbie trying to learn the code of the thc300 post processor. Some examples of specialist posts include machines with multiple heads, like a plasma cutter with a punch marking head. This service is normally free unless the post is particularly complicated. Custom Post ProcessorsĬustom posts can be written to your specifications. The programming language used is versatile enough to cope with pretty much anything you could possibly want a machine to do. If you so wish you can create your own posts. Unlike many CAM packages the post format is freely available and documented.

These can be fine-tuned to produce code for virtually any machine. To get over this, SheetCam comes with a wide variety of post processors. While G-code is theoretically a standard, most machines have their own dialects. To prevent corner rounding, the corners can be looped. As the small holes are too small to fit a full sized lead in and lead out, the leads are reduced in size to fit. In this example, SheetCam automatically works out the holes are inside so it reverses the cut direction for these features. SheetCam gives you many options to optimise cutting. Once you have defined your tool you can set up the cut. This increases consumable life and reduces faulty cuts due to blocked or obstructed nozzles

Instead of plunging straight in, the cutter torch can ramp in, reducing the amount of material blown back into the torch. Automatic cut ordering to ensure that inside contours are always cut before outside contours.Draw your part the size you want and let SheetCam work out where to run the torch. You can define as many tools as you like for different materials etc. The tool definition allows you define all of the important parameters for cutting.
