Hi @ThaliaFromPrussia !
The “PIN” mentioned in that BambuLab doc is for pairing/binding inside Bambu Studio, and the X1/X1C doesn’t use that same PIN flow.
MMM-BambuLabNotify does not connect using the Studio PIN, it connects over the printer’s LAN MQTT (TLS) interface using the printer’s LAN Access Code (sometimes just shown as “Access Code”) along with the printer’s IP and serial number, see the README for where to find those.
Unfortunately, I only have an A1, so I’m not able to personally verify that MMM-BambuLabNotify works with an X1/X1C. But, if you’re able to get it connected using the proper Access Code, I’d appreciate confirmation.
Thanks!
