Hello all,
PLA stringing has been driving me crazy. After spending about 20 hours of making small calibration tests to get rid of blobbing and stringing (ABS is so much easier to work with!), I think I finally got this working to the best of my ability. I reduced stringing about 90% and was still able to print at 180C. Oddly enough, speeding up the print, lowering the Z-Lift, making it retract just about every non-move, and a few other filament tweaks such as having no length on restart seemed to finally make the difference for me. So, I went ahead and took on a big challenge with the Petal Vase. I was very happy to wake up this morning and walk into the cave and see this sitting there.

Couldn't be happier, and more importantly, my wife was happy with what I printed her because I've been spending a little bit too much time with my new girlfriend RSMV2

Came out beautifully! Thank you for sharing!

Ha! I printed that very same object about a week ago. Had strings all over the place.. Looks nice in white.

Yeah, the strings were a pain. I created a mini string tester that I can print in about 4 minutes flat. I was able to do dozens of tests without burning up my filament before i finally found the sweet spot with as few strings as possible. I was pulling my hair out but man, i learned a lot about the printer and all of the crazy settings. Interestingly enough, temperature only had about 25% to do with it. The rest of it was retraction, retraction rate, length on move, and movement speed between non-printing moves. It had to suck in that material fast, start moving very quickly with that fan blowing on it so that the string would break, and then not extrude that starting 0.1mm before it started on the next part it jumped to. That got rid of the blobbing and about 90% of the stringing. Whew!!!

Oh...and then I changed to a black PLA from the clear and had to start over. This Black PLA behaves very very differently than the Clear PLA. <sigh>
