- MACROS are new to us, but you can get an idea of the more obvious use cases here https://forum.onefinitycnc.com/t/macros-files-for-bb-official-thread/25091
- Yes, that seems like a possible macro use, for repeat production use.
- I don’t think macros can modify other files. I haven’t used work offsets, and am not an expert but it does seem like you could setup macros to change your work origin (Home) to various preset absolute machine coordinates.
Hope this helps!
