Anders,
This is great news, and I'm happy to see the other updates you're working on.
Your opencamlib is great. I used it to generate tool paths for the original positive used in the mold for these castings:
Opencamlib had no problems. By contrast, the smallest part, 1/2 of one foot, gave two commercial/proprietary CAM packages trouble: SprutCAM instantnly threw an error, and VCarve worked for 12 hours before we gave up and stopped it.
