No extrusion at last part of layer

Posted · No extrusion at last part of layer

Material flow stops close to layer end and I cant find settings in Cura that might do this.

Looks like excessive coasting but that is not enabled.

Width are roughly 4-5 mm

Smart Z-seam hiding is enabled so I get this at mixed locations, both inner and outer wall

 

Any hints?

    Looking at second picture and third layer (Z1,9) it seem to start at X75,762 and end at the same if I read the file correct. Gap is in the X-axis

    I assume the last G0 movement is wiping the outer wall

     

    Start outside layer3:

    G0 F600 X152.136 Y300.658 Z1.9

    End outside layer 3:

    G1 X66.053 Y163.658 E0.34474

     

    Same part but arc welder enabled makes the code easier to read to me, knowing what is circular and straight motion.

    However, I did not save this as a 3mf file and might have moved the model so X and Y positions cant be compared but it seems to do the same:
