Hi Charlie,
Thanks for looking into the issue! I tried with the 1.47a build (placed the EXE in the existing 1.46a distribution as suggested), but unfortunately still got a crash using the same scenario, at the same moment, when the toolpath is being computed and shown.
Here is the new log: PixelCNC 1.47 test - Pastebin.com
I hope this helps ! Let me know if you need any additional information.

Ah, it looks like your cut depth is set very very tiny, which is OK for horizontal finishing passes (i.e. horizontal milling operation with a cut stepover of zero) but for a parallel carving operation you'll want something more substantial. It looks like it's overflowing the Intel graphics chipset with too many cutpath move geometry and crashing it. Try a larger cut depth. If your cutter and machine are rigid enough you should be able to use the entire flute length of your cutter for your cutting depth. For a 1.5mm diameter cutter I would use at least half of the flute length as a cutting depth here.
Another strategy is to use a roughing pass with a larger cutter that has a Leave Stock of a millimeter or two, a stepover about 30-40% of the cutter's diameter, and then come in with a parallel carving operation and the smaller tool for finishing - and you can set your cutting depth to the full depth of the project's canvas (or at least the cutter's flute length).
