Perhaps you could make a test cylinder for us to try with whatever program you're finding less problems with?chuck12 wrote:I've been fighting the same problem for quite a while when printing round or curved objects sliced with Slic3r 9.8 or Creator, I'm glad you posted this
because Creator allows me see it is not hardware or firmware issue. If I turn off random line starts I find line starts and stops (are not) the only cause
of the bumps, I could actually watch prints sliced by Slic3r randomly placing tiny blobs on perimeters, perhaps for bonding inner and outer shells.
I've been wondering if these are actually artifacts generated by some CAD conversions to STL. files because prints I've done modeled with true
solid 3d software seems to have fewer problems altogether.
I just test sliced this and the blobs/spikes are still present in the preview, they were probably just less evident on your print for whatever reason. I've yet to have a single curved surface slice without the blobs appearing in the gcode.crank wrote:I am having the same problem on my M2. However, I have a hypothesis that it is related to .STL generation and what software/settings that are used to generate that .STL . I have downloaded a couple of models, circular in nature, from Thingiverse and they print completely fine. However, any of my own models that are circular in nature, done with SolidWorks 2013, have the same recurring blob pattern(RBP syndrome) no matter what. Anything that is NOT circular in nature, prints just fine even when I model it in SolidWorks 2013.
Try printing http://www.thingiverse.com/thing:32203 and see what you get. I used it on calibrating my Lay Woo-3d filament prints and I am now using it to tackle RBP syndrome using PLA. I had no recurring blob patterns when printing that thing in either PLA or Lay Woo-3d.
