If you use SheetCam for plasma or laser cutting, you’ve likely experienced the frustration of a "hot crack." You load your DXF file, generate your toolpath, and everything looks good—until the machine actually starts cutting.

When we talk about a hot crack in SheetCam, we are usually referring to corner overheating . This happens when the cutting torch has to slow down to navigate a sharp corner. As the machine decelerates, the torch dumps more energy into a smaller area for a longer period.
