I have Ultimaker 2 Plus Extended for about 2 weeks. Last night, I try to print the wind turbine that is provided in Youimagine website. Here are some pictures from the prints (I printed the top blade - Group A) . I used the settings that are recommended in this link "https://ultimaker.com/en/tips-tricks/19639-vertical-axis-wind-turbine"
I also did not change any settings from the machine, for example, the acceleration is still 3000 mm/s^2, and the jerk also the same as 20 mm/s
After the first print, I changed the orientation of the print and move it a little to the back of the bed, close to the z rod. The result was a little bit better, but I noticed that at a certain height, the quality was getting worse
There are also some imperfections in the blade, I guess that have to do with the retraction problem and I am not worry too much about it
Beside the inside of the blase was bad, the outside looks perfect for both of my prints, I guess that is what the designer intended.
Is there anybody has the same problems with me?
Any suggest on how to fix it?
Thanks
