And the next print that was in progress, cleaned up of all the stringing, about .1mm too big. Pretty good for a SWAG. Making the next one with 30% more infill in gyroid pattern, .1mm smaller, which will also improve the wall strength a teeny amount. Then it might be time to rig it on the motor, add some plastic lube on the bb's and drive it for a day to see what if anything breaks. Added a mm to the retraction got rid of most of the stringing. At 2mm high its a whole lot cleaner a print. If it doesn't plug up. It is still using retractions by the thousands. And I still don't have a side fan, its hot enough to burn a finger but not running. I've sent a msg to the vendor but no reply as yet. PETG doesn't want it, but this is the starter PLA. Thanks lar3ry.

Thanks, that’s one possible cause I’d never have dreamt of! Plausible reasoning though. However, that image was received by several here. Highlighting difficulty of gathering practical evidence. Bit like “Can you hear me at the back of the class?” -- Sent from: http://forum.openscad.org/
