Printing after seam travel


Recommended Posts

Posted · Printing after seam travel

I’m having an issue printing an airplane wing. When traveling to a seam the flow stops and then starts but the nozzle moves along the wall before fully flowing creating skips and ultimately a porous area. I have retraction off. Using Cura 4.13.1 and Anycubuc Vyper printer.

    Load the model into Cura and adjust you settings the way you want.  The use the "File | Save Project" command and post the resulting 3mf file here.

    I'm assuming this is a single wall model.  This can be a hard one to nail down as it is almost always a function of the amount of oozing that the nozzle is doing during the travel move between the last extrusion, and the next one.  Sometimes you need to rotate the model, other times rotating the infill (line directions) can help.  Limiting the travel between the end of one extrusion and the start of another is a key.

    If you had retraction turned on then you might consider adjusting "Retraction Extra Prime Amount".

    There is a post-processor for "Retract Continue" that does a slow retraction over a distance, but again, you have to have retraction enabled and I seem to recall that the plugin is confused by Zhops.

    Under "Travel" there are boxes for the layer start position.  You may be able to adjust them and move the start to the Zseam position.  Combing is another adjustment.

    In the Cura preview - turn off the Shell and Infill and turn on "Travel Moves".
