One print head is dragging the material that is being printed over the piece

Hi guys

 

I need help with the next problem. One print head is dragging the material that is being printed over the piece (rough lines in the picture). I do not know if it is my impression but I see the right print head downer than the other one (photo with the yellow mark). How can I fix that?

 

Regards.

That is normal that one nozzle is lower.  The head currently printing will always be lower.  Manually push the switch on the print head and you can see it changes which nozzle is lower.

 

To get rid of those "dragging" lines go to the parameter:

combing mode   and set to Not on Outer Surface
