The problem is, sometimes the printer prints, sometimes not. I have tried many things in OrcaSlicer, upload from OrcaSlicer, export and upload manually. both work. but not always. I don’t know if it’s because of the settings or if something else doesn’t want to. reinstalling didn’t help either.
in the zip file are the log file and the printer.cfg
okay, that doesn´t worked. i have installed klipper new and updated the firmware. now he prints. now i can adjust the fluw rate and every change doesn´t effect on the testprint. But I am looking for the problem.
