BambooFill and Stringing

Does anyone have experience using Bamboofill PLA(from eSun), and if so, what settings did you use to reduce the stringing. I've attached a picture of the part in question, and if comes out looking GREAT, it just happens to generate a lot of strings during the process. I print at 210, with bed at 55; but at 215/65 for the first layer (which helps for adhesion the bed). Anyway, I've search the web, and it gives some indication of changing retraction, which I have varied from the 'standard' setting (1.5mm @ 30m/s) to 5mm at 75mm/s without a noticeable change. Perhaps additional retraction would help, but I don't know what the LIMIT to this is, but if someone has done this already, please let me know.

When I printed with wood, there was more stringing, simply due to the nature of this filament. It is easily removed with a small stiff brush.

I believe that the maximum retraction speed (in firmware) is 25 mm/s; settings above this have been known to make the retraction slower.

In any event, I don't think additional retraction will help; all it will do is suck air into the nozzle which will hinder proper extrusion.

Have you tried lowering the temperature? Maybe 195 degrees.

You could also try a different slicer to reduce the number of moves and retracts or to perform a longer wipe before moves. Also increasing the move speed/acceleration will help. Maybe even try with only 0.5mm retraction (or none at all). Yes that is counter-intuitive, but getting the moves done quickly (without waiting for a retract) can help.

Thanks Peter,

You are right in saying they are easy enough to mechanically remove, it just seems best not to create them at all.

The slicer used is Slic3r. I have also used Cura, and am now using Astroprint, both are integrated into their cloud slice capability. The settings are different, and I don't have an understanding of how they can be configured to create less moves, which sounds like a reasonable assertion for how to reduce the strings. Could you elaborate on how to configure a slicer to do less moves?

Hi Stephen

Sorry; can't help with that as I don't use Slic3r and only use Cura for quick prints where quality is not so important.

I think the Cura setting is "Enable Combing", but I never really got to test out the results.
