Dear Users, the auto-leveling of our UM3 printer is not working at all: When starting a print job the auto-leveling starts but the nozzles do not approach close to the bed. The auto-leveling stops and this error-message appears: -Active levelling could not be performed. Please check the nozzles and bed and try again- We already checked the printcores with nozzles and cleaned the bed with water. We tried manual leveling but without success. We also followed the instructions of troubleshooting in the manual but we cant find the problem why auto-leveling is not working. We have attached the last log file. Best Regards logfile_20200109.log
