From the project
Expander board for Bambu Lab X1 Carbon
This repository contains hardware development files for the X1Plus Expander, available-ish for purchase at Crowd Supply. Printer-side software to interface with these boards lives in the X1Plus repository.
If you have just purchased an Expander, you probably want to read the getting started guide!
Each part has its own directory in this repository. Part numbers always begin with "X1P", are followed by three digits to identify the part, and have a three-character revision number: a letter to identify form/fit/function-incompatible revisions, and two digits to identify FFF-compatible…
