[Striping because of head direction changing]

No workaround for me.  The parts were designed to be sliced in Cura 5.2.1... cannot go back.  I'll have to live with the ugly prints.  Hope it's fixed soon.  Thanks.

I posted the part as requested but no response from admin.

So there's no solution for this problem?

Hi @MariMakes,

 

Please find attached a Project file containing the part that is printing with bands of shading because the direction of the print head changes from CW or CWW to the opposite direction.  The owner of the files was kind enough to let me send the file along to you.

 

I'm printing on a Prusa MK3S+ with Galaxy Silver Prusament and I'm using Cura 5.2.1.

 

This part sits horizontally on an airplane wing.  The top of the part is the taller of the 2 sections and it oriented toward the back.  I wouldn't really care if the bottom of the piece had banding, but the top part being so visible... and not being painted, I'd like to look it's best.

 

I've tried many combinations of Z Seam Position, Z Seam X, Z Seam Y, Seam Corner Preference and Z Seam Relative.  I've tried changing orientation, position on the bed... so many different combination.

 

The printer is solid.  All other parts are printing beautifully.

 

Thanks for looking at this.  Please let me know if you need more info.

 

Cheers,

 

David

Hi @MariMakes,

 

I don't own the file (it is part of a paid download) so I'll need permission to post it.  I'll try to get permission and if it's ok I'll create the project and post it.  Thanks for the response.  While watching the print, I can see where banding will be because the print head changes direction from CW to CCW or from CCW to CW.

I'm trying to figure out how to prevent this striping.  The cause is the print head changing direction from clockwise to counter clockwise... and back again.  It's so random.  Sometimes I can change the orientation of the part and that will solve most of the issue.  On some parts, however, sometimes after a hundred changes, changing seam preference etc. there's no stopping the striping.  I'd love a feature that says "print clockwise" or "print counter clockwise" or something like that.  I'm using Cura 5.2.1.  The image attached shows the issue along side a print with no striping.  Thanks.
