If basic troubleshooting doesn't resolve the hot crack error, try these advanced techniques:

Start the pierce away from the final edge of the part. This ensures the "hot start" and initial puddle instability don't occur on the finished geometry. This public link is valid for 7 days

If you cut all the small holes in one corner of a part consecutively, that area will become extremely hot, increasing the risk of hot cracking.

Sharp internal corners or "dead ends" in a cut path can trap heat, leading to localized stress. How to Prevent Hot Cracking Using SheetCam Can’t copy the link right now

In your SheetCam tool settings, optimize your Pierce Delay . It should be just long enough to penetrate the material completely, but not a millisecond longer. Excess delay pumps unnecessary heat into the plate.
