While doing some basic CNC operations, running boundary, clicking play to run job, I have seen this error twice and no clue how to troubleshoot. Contrary to appearances, it’s not fatal. My CNC job is running right now behind the error message, and before that the boundary run completed successfully. Clicking “X” dismisses the error and I can go on my way. Just seems like some bad error control at the very least.
Yup, I get it (work in the software industry) and have gone to the luban repo before for other stuff. Have you had luck getting issues acknowledged on github?
