Excessive stringing and axis shift.

I printed this heart (see link) at 50% size. I used no support and 100% fan. I got a lot of stringing as can be seen and also just near the top (actually the bottom) of the stem there is a shift of about 0.25 mm in X+ for about 8 mm then it returns to when it was before. I used 100% fan because I noticed this helps immensely with small thin parts. I also did not use my makeshift enclosure because small parts don’t like it. Anyone else notice this?

Thanks, Dhatw.

To solve this issue tight grub screws at pulleys connected with X axis motor (this is motor at right side).

Thanks Martin, I will try this but what about the stringing?

100% of air flow create additional pressure in hot end so additional stringing can happen at long jumps but it is removable just by finger nail, it is not injection molding machine but rapid prototyping which sometimes need small post processing (for this toolset is included).

This is probably obvious, but also printing each piece individually will greatly reduce stringing.

No problems with 100, 75, and 50%. I did cover sides. Fan I think was default. Finished pics in another thread at bottom of pic. http://zortrax.com/forum/viewtopic.php?id=279

That’s interesting, because I always use a 20 mm cube to test out the newest f/w & s/w and when I enclosed the printer the X+ (opposite side of fan) side was horrible. I removed the panels and it became much better and when I increased the fan to 100% it was almost perfect. It was still not quite as good as the first ever 20 mm cube I made though. Did you get any stringing? I have already made 4 heart shaped picture frames that are not to my satisfaction and I am running out of time :). It is getting increasingly harder to hide these from their intended recipient :).

Dhatw.

No stringing at all. I painted them right after I pulled them from printer. No clean up.

Yep… updated everything.

I went around and checked all the grub screws Martin, none were loose. I have only made one print after this but it did not have the same issue. We’ll see how it goes.

Thank you, Dhatw.
