My print goes about about halfway and gives me an ER34 error. I’ve changed the print cores and reseated the print head multiple times. It keeps giving me the same error. It’s only when I print larger items that it gives me this error but I can print smaller prints without this problem. What else could be giving me this problem. I can print the same file on other printer with no problems. I’ve updated the software as well.

    Thank you for responding. That was the first thing I did, and I did what it said.  I think the file was too large, so I put it on a USB drive instead of sending the file through the network and it printed the part.

    I also starting getting ER34 on my S5 this week. Took apart the cable clamp and the black shield/gnd wire has pulled out, seems like the little metal locking tab sheared off. This should be recrimped but for now I just shoved it back in and retightened everything and is working again for now.


    In my experience this is a major weakness in the design of this connection point because my UM3 also suffers from this problem a lot more regularly except there is no obvious pin damage, I just reseat the connector and it tends to go away for a while.
