Ahhh, might be a reason for your prob.

Question, how did you do the connection to the wire?

- Just a bad crimp connection?

- or soldering the wire to your “U-Type Wire Connector”?

I have the crimper recommended by the Voron team. And it actually is not the issue as I stated above, it didn’t help after adding them.

I decided to replace the part with the EBB SB2209 USB V1.0. I had more than one EBB SB2209 CAN and all made issues after some time. So I will try the new one 🙂 I will keep you guys posted

Yesterday I got the EBB SB2209 USB V1.0 and it works like a charm. For now I don’t have any issue with this part. What I find interesting, the EBB 36 CAN works on four printers we (dad and I) have without any issues. Maybe the EBB SB2209 CAN has many bad batches.
