I just uploaded a new build that fixes the crashing that could appear when calculating the toolpaths for image geometries. I’m not sure when this bug got put in there but it should have been evident for quite a while. I had a user, John K., that put some heavy duty debugging work in to help me find it. It ended up be due to the multithreading try to read and write the same memory locations at the same time. Rookie mistake.
I have a couple of more outstanding bugs to work through in the next week or two and then this will be moved to the main download page.
