Here is a deep dive into why this happens and how you can use SheetCam’s powerful toolset to prevent it. What is Hot Cracking?
SheetCam isn't just a tool for generating G-code; it’s a tool for managing . By adjusting how the torch interacts with the material, you can significantly reduce the internal stresses that lead to cracking. 1. Optimizing Lead-ins and Lead-outs sheetcam hot crack
Use SheetCam’s Optimization settings. Instead of cutting the "closest next" part, you can manually sequence the cuts or use a "keep cool" strategy. By jumping the torch to different areas of the sheet, you allow the material to dissipate heat, keeping the overall temperature of the HAZ below the critical cracking threshold. 4. Cutting Speed and Feed Rates Here is a deep dive into why this
Setting a small overburn (cutting slightly past the start point) ensures the metal is fully severed, preventing the mechanical "tearing" that happens when a part is forced out of the skeleton. 3. Heat Management through Cut Sequencing By adjusting how the torch interacts with the
Not all metals are created equal. If you are using SheetCam to cut , your risk of hot cracking is much higher.

Use SheetCam to create longer, curved lead-ins . This allows the pierce (the hottest part of the process) to happen further away from the finished edge.
