Has anyone managed to print Ultimachine PLA without getting strings on moves? I’d be interested to hear what settings you’re using, I haven’t been able to get rid of them entirely.
Attaching a couple of photos of the make magazine torture test, stringing is visible.
Are you using retraction?
Agree with @Terran_Schatz retraction usually cleans this up. If your Z axis is a little “bad” you might use Z lift as a bandaid (lube your Z axis) but it is probably smarter to find the root cause (wrong Z cal, over extruding due to wrong nozzle or filament size in slicer or bad E cal).
I will try the torture test tomorrow. Where is the STL?
Dooh. Misread. I have Ultimaker PLA.
I modded my printrbot simple to have a Bowden extruder and also got significant stringing. Retraction didn’t seem to help much. It was so bad I eventually had to give up and go back to the stock extruder. Any other tips on how to defeat stringiness (and blobs) would be much appreciated.
retraction + tweaking the temp should fix it
I’ve printed at temps from 175 to 210, and I’ve tried various retraction speeds and distances, with and without z lift on retract. I have managed to get completely rid of strings using other pla, but Ultimachine is widely regarded to make good plastic as far as I know. So I’m wondering if anyone has managed to get rid of the strings, and what their settings were.
@Peter_Parnes stl is here http://www.thingiverse.com/thing:33902 and my recent post here notes some key parameters to avoid knocking over the arch when printing without support: https://groups.google.com/forum/m/#!topic/makergear/A9Nj1uoNbSQ
