Just a simple straight to the point video showing a firmware issue on the P1S and how to revert back to a previous version. This method works for all Bambu Lab printers!

✅On the side of SteinWipe Motion Control Macros featured in this video, the project continues to evolve based on feedback and support from the community.
Update Feb.2026 :
The project is now solid for P1S P1P X1C with AMS! This project is still active and you can find it here:

There are tons of new features and Ive discovered many better ways to tackle everything from installing the wiper to SteinSwitches, if you want to go down the new and improved SteinWipe project rabbit hole, these videos and links below are the perfect place to start (in order)!
