  1. I will do so once one more boat finishes....! I do not expect a difference but this one is at 50% infill. There is one other user on this thread that has the same problem and the post from the people that designed the little shippy that there might be others as well. So, this is either firmware and it fails for all, or it is a limited edition hardware defect that only impacts a small lot of production printers? One of the strange things is that it only happens on the cabin...not on the engine box right behind the cabin. Made the infill idea sound logical as there is none there. Which makes the firmware idea more possible. Puzzling.
  2. Well then. I have not had the Ultimaker 2 long and may, or may not, see this phenomenon again...but...I would really like to not see it on this test case. Obviously there are at least a couple other folks with the same issue. Does anyone with a U2 print this cleanly? I would love to hear from someone with a profile that works...or one that does for them and not for me... Puzzling.
  3. I printed at 10% overlap and the lines are still evident. I am not even sure it is worth going lower as the look exactly the same! This feels like an issue with the Cura slicer except that I get the same thing when I use Simplify3D...which makes it an idiosyncrasy of my particular Ultimaker 2 (as I find it hard to believe no one prints without Zebra effects)?
  4. Just did a version of this in Fast mode (20 micron layers), at 210 after 1st layer, 15 second minimum layer, 3 shells, and with the speed dialed down: 30 overall, 20 bottom, 50 infill, 20 top, 20 outer. Still with stripes.
  5. I am back after quite a bit more experimentation. I had a filament feed issue that needed correcting. Fairly occasional clicks from the extruder driver are now gone. Not sure if this was a factor but figured it needed correcting. Having done that I stepped back to some basic Cura settings: Normal Setting 15 Second Minimum Layer Time Hotend to 110 After Layer 1 All other settings were per the Normal profile. Very visible zebra stripe still there. Some lines on the outer rail as well. The tops of curves in the ports are a little messy but better than with the 5 second minimum layer time. I would be reasonably happy if it were not for the zebra stripe. Here is the g-Code for the above. Following the above I did a Normal print will all the same settings but went to four shells and got the following: Could be really happy with this print but for the lines!!! I guess the good news is that I can print the little shippy on my Wanhao Duplicator 4S without it looking like a zebra: Finally...I have also now tried under extruding with no change and am currently printing a slow motion version which should be done shortly. I have also posted a comment on Thingiverse asking for help as this is a very active thing there and I have to assume someone with a U2 has printed it without stripes!
  6. Have tried the outer to inner to no avail. Still a zebra. Will try speeds next but have to print a useful part first :-0 Thanks, Will
  7. Hmmm...now that you mention it...I would be glad to take advice on any of the above! I can print the same model on my Wanhao Duplicator 4S without any of them! The one that was irking me the most was the first one you mention. Gotcha on the shell and the first layer.
  8. Belts seem tight. My shell thickness was 1, which I changed to 1.2 as my nozzle is .4 and Cura did not like the non multiple. Don't think this was the issue as Simplify3D had exactly two shells and same problem. I will try speeds but first wanted to try the outer - inner. I am running the latest Cura but did not see it as an option so am trying Simplify3D which does support that feature and also the zebra artifact. What artifact indicates temperature to low? I try to extrude at the lowest possible temperature on my other printer but the U2 seems to run hotter? Is 210 in the ball park for PLA? Thanks, another swing or two... Will
  9. But only on two sides and only at a certain level?!? The stripes appear on the other side as well. Have not tried rotating yet but will. There is a flat surface out of sight to the left below the side of the boat and it does NOT bear stripes! Thanks for any pointers! Will
