Strange Z-Scar behavior

[Schoffra 1]

Hello everyone. I recently bought a used S5. So far I am very happy with the machine. But it seems to have a strange behavior. As you can see on th pictuer there is a perfect wall on one side of the z-scar and some kind of offset on the other side. The offset keeps on going till the wall ends into an opening on the other side of the model. 

Short belts should be tight and material is as dry as it can be. 

Any suggestions?

It's most likely underextruding at either the start or the end of the seam (more often at the end). Try increasing Walls > Outer Wall Wipe Distance (if you can't see it, just search for it) to 0.2mm and see if that helps. If it makes a difference but it's not quite good enough then increase it a little at a time.

 

If it doesn't seem to be making any difference, then feel free to post back and I'll see what else I can pull out of my head.

Ok thank you so much. I will try that.
