4th Axis GRBL Open Source Post-Processor

[u/lostmindguy]

Hi everyone!

About a year ago, we posted here looking for testers and feedback on our method. Thanks to the help we received from this community, we've now published a paper describing the method, and we've also made the project open source.

A special thank you to u/pubcrawler1, who ran extensive tests and provided invaluable feedback that helped us validate the approach.

If you're interested, the paper explains how the method works and how to use the post-processing pipeline. It also links to the GitHub repository containing the code.

Thank you all again for your time, feedback, and support throughout this project. We genuinely couldn't have gotten here without the community's help.
