While trying to help a user who had problems running a g-code file, I observed the g-code would crash my system when running the file check. Details are in the other thread.
I’ll test the latest firmware/slbEXT on ioSender and gSender but it seems to happen regardless of sender, so not a gSender specific issue. I’m wondering if there’s an issue with planning the small movements on the firmware side.
Closing this since it’s outside our control (firmware) and also fixed in modern grblHAL versions. Thanks to everyones hard work in the original thread in helping him clean up his toolpath.
