Hello, so this is kinda a new error, since before it wasn’t happening and now it is. So everytime i start a print it does everything but once it comes to Eddy Calibration, it just stops moving and it wont go any further unless i cancel the print. Now i realized this mostly happens with orcaslicer, when I start from mainsail it works just fine. So what should i do? EDIT:When selected Eddy Calibrate on the small screen, it works fine. ---

Start a print known to fail. As soon as it fails use Mainsail to download klippy.log to your PC, zip it and upload here. Also open the g-code with notepad, copy/paste the first 500 lines (±50) and zip and upload (may have to be a separate post) ---

I fixed it by restoring klipper to make it use a earlier backup and it fixed it.
