Travel causing stringing (PETG)


Recommended Posts

Posted · Travel causing stringing (PETG)

I have played with travel settings a little but I can't figure out how to make i stop doing this. Let's say it is printing a rectangle. There are 2 points while it is printing that rectangle the nozzle does a diagonal travel move to the other side of the rectangle. I have dialed out all other stringing except for the triangle caused by this travel move.

 

I have combing enabled to travel over the part except skin. Travel move speed is 150mm/s. Coasting enabled at 0.8mm3 for a 0.4mm nozzle. I don't get stringing anywhere else currently and it took me a few days to dial that in.

    Yes you are right. But those come off with the wipe of my thumb. Anyway I don't know what benefits combing provides. I just tried it as part of my PETG stringing attack. I'll disable it for my coming prints.

     

    I wonder if coasting volume will need to be changed. In any case I'll try Linear Advance when I understand Marlin better.

     

     

    Also I've been watching this print and it's doing fine now. It seems to only happen near lower layers whether it is traveling over printed area or over brim/glass/brim. The travel move happens successfully and leaves no trace of stringing. The lower layers print much slower.

     

    I just noticed initial layer travel speed is only 100mm/s I'll raise all travel to 200mm/s and disable combing and see how it goes.

    Modern art 3D printed 🤣 - sorry!

     

    Unfortunately I have no idea why it is so bad, but can you upload the Cura project here to see all you settings,

    Sure as soon as I get home. Thank you. On reddit people are asking me to frame it so I ordered a new bed.

    So the other thing just so you know is that I'm using Octolapse and someone on reddit mentioned that there are retraction settings for Octolapse. So probably the issue is there.

    BTW, it just occurred to me that which I was complaining about the consistent travel moves at certain points of time were due to my timed 30 seconds profile I used.

     

    Octolapse truly is a new artform.
