Firmware update Tec 4.1 not possible and z-banding

Post by jmffo »

Hello,
I am having a problem getting an update to work successfully at all. The connection via Repetier host with the DRucker is ok. I can retrieve firmware information. As soon as I click the upload_automatic.bat file comes the following error message:
Der Befehl "wmic" ist entweder falsch geschrieben oder konnte nicht gefunden werden.
No printer found!
exiting batch file...
Drücken sie eine beliebige Taste...

Then I have a second problem with clearly visible z-banding. How can I prevent this. I have already changed the belts and adjusted the tension optimally. The temperature variations from the builtplate and extruder are +/- 1°C. It would be nice if someone could help me.
Many thanks in advance.
Jörg
