  1. What do you think think banding near the sharp corner is about?
  2. Gotcha. I think the default values on my ultimaker 2 are 3000 for acceleration and 20 for jerk.
  3. One more print for reference in case they provide new clues. I printed this PLA at 205C, 50mm/s speed, 1500mm/s acceleration, 12mm/s jerk.
  4. Thanks again geert_2 — tonight I will be getting a new Bowden tube and clips. I'll try to install that, and try your cold pull method. I inspected the teflon coupler when I took apart my hot end, and it was still perfectly white and looked undeformed — I'll check again. There seems to be some regularity in terms of Z issues — perhaps my axis and screw need deeper cleaning...
  5. Thanks geert_2, I've visually inspected the coupler and it's looks clean and undeformed. But I'll try your method to see what comes up. Are you suggesting a these steps because you are recognizing something in my prints? Do you have an idea of what's wrong? Thanks!
  6. Thanks gr5 — i just finished a print slowing down speed by 50% and acceleration by 50% and this is the result. As you suggested the thicker walls make a big difference. I am still seeing uneven z issues, as well as ringing. Any other suggestions? I am printing on an Ultimaker 2.
  7. I've changed to a new spool of PLA from MatterHackers, I remembered that I had no idea how old the black PLA that I was printing was. I just printed a benchy with very mediocre results. I am also attaching my GCODE in case there are clues in there. Thanks for your help! UM2_3DBenchy.gcode
  8. I am new to home 3d printing. I've inherited a rundown UM2 from my work. It had not been used in a few years, dusty and miss-aligned. I tried my best to bring it back to its former glory but so far I have not managed to get high-quality prints that have fine details. The work that I have performed so far: tightened up all case screws cleaned up and reassembled feeder cleaned up and reassembled hot-end tensioned long and short belts aligned axis with alignment tool greased rods and z-screw My setup: Cura 4.1 Olsson Block E3D 0.6 Nozzle esun black PLA 3mm If I print simple shapes the prints come out pretty good. When I print things that have fine detail I get what I think is a lot of ghosting or ringing. I am also having major retraction issues. Below are a few test prints — any guidance on how to troubleshoot my issues would be greatly appreciated.
