Resonance of nozzle gives pour quality

With a steel wire of 0,2 mm I could make the nozzle run again.

A serious problem is the position shift during printing of 1 or 2 mm. Work of houres is wasted this way. How can I prevent this?

Where did you position the end stops?
Did you re do the cable assembly?
Can you post a picture?

The cable

was all right. The program far from the end. It happend before.

From your reply I assume you did not mount the cable as shown in the instructions.
If you don’t build the machine the way it should be I can’t help.
Sorry.

How can you com to this conclusion? It was according to the instructions.
