Posted (edited) · how do I reverse my S3 to firmware 6.2.2

Hello everyone,

Since I update to the next stable version 6.2.3 all my builds are failing with the ER45 error. Before I go ahead with the repair or sensor changes I would like to reverse the firmware to the last stable version 6.2.2 which was working well. I did the manual alignment of the table and didn't help. I've tried to find the firmware on the Ultimaker website without success. If anyone can help me with the firmware I would appreciate it!

Best regards,
