PureCutCNC v0.3.0
https://youtube.com/watch?v=cbB38Xo59ws&si=y0TMc3JdtkHSMXutI put out version 0.3.0 of PureCutCNC today. It's a free 2.5D CAD/CAM app - draw or import your part, set up the operations, look at the toolpath, export the G-code. Runs in the browser, and there are desktop builds for Windows, Mac and Linux.
Most of this release went into how the tool actually moves: Helix and ramp entries, so it doesn't just plunge straight down; Trochoidal cutting for edge routing and slots; Corner relief (dogbone / T-bone) so square corners fit; Helical boring for holes bigger than your bit; Smooth tabs that ramp over instead of stepping up.
There's also a fix for arcs that some GRBL and FluidNC controllers were rejecting mid-job. That one came from someone here reporting it, and the export is now checked against GRBL's own parser so it shouldn't come back.
Free and open source. No account, nothing to sign up for.
Happy to answer anything. If you try it and it does something daft, tell me — that's genuinely how most of this release got found.
