johnnk 0 Report post Posted February 25, 2015 in Uneven PLA extrusion Greetings, done the atomic method several times. Extrusion of PLA filament still seems problematic. Here is a photo of print results. It seems to be uneven extrusion. Any suggestions are greatly appreciated. http://umforum.ultimaker.com/index.php?/gallery/album/1864-jdchs/ Share this post Link to post Share on other sites
gr5 900 Report post Posted February 25, 2015 in Uneven PLA extrusion That's severe underextrusion. Maybe 30% of what you need (one third). I'm thinking you might be printing too cold or too fast. Here are recommended speeds for .2mm layers. If you are printing .1mm you can print twice as fast and so on: 20mm/sec at 200C 30mm/sec at 210C 40mm/sec at 225C 50mm/sec at 240C If you don't know your printing temp or your printing speed, get out of Cura quickprint mode to find speed. And go into TUNE menu while printing to get temperature. Share this post Link to post Share on other sites

visu-al 2 Report post Posted February 26, 2015 in Uneven PLA extrusion 120mm/s and 0.2mm layer height??? gr5 is right it's about 3 times more then what would be ok Share this post Link to post Share on other sites
IRobertI 428 Report post Posted February 26, 2015 in Uneven PLA extrusion Indeed, that is way way too fast. Also, why are you turning the bed heat off part way through the print? If you do that you can actually have the parts pop off the bed before the print is done which would ruin the print most likely. Share this post Link to post Share on other sites
