It seems there is a bug with Cura 4.7.1: https://github.com/Ultimaker/Cura/issues/8321 People say that with 4.6.2 there were no such problem.

Hey guys, Along with the Cura settings I mentioned above, I've also added a 3D printed motor mount for the Z Stepper and adjusted the motor placement and tightened some bolts etc. aaand I've probably printed the best 3DBenchy I've ever printed. The Z stripes are reduced a lot (still see some though). So I'm happy. "Darısı başınıza..." Cheers,

Ookay my problems are solved: So the main problem was, as I stated in my previous post, the "Compensate Wall Overlaps". Because with this option my "Max Resolution" setting was ineffective. What made it even confusing was that in the mean time I thought my "Max Resolution" setting was too big and reduced it from 0.5mm to 0.01 mm thinking that I was eating a lot of detail with a huge dimension like 0.5mm. So after disabling the "Compensate Wall Overlaps" setting as suggested by @campervd, I didn't see to much improvement because my "Max Resolution" setting was still around 0.01 mm. So the photo labelled as Before has the Compensate Wall Overlaps setting on with normal printing speeds. The one labelled After my settings were: Z Seam Alignment: Shortest Compensate Wall Overlaps: Off Maximum Resolution: 0.5 mm Maximum Travel Resolution: 0.05 mm Maximum Deviation: 0.05 mm Print Speed: 75 mm/s Infill Speed: 75 mm/s Outer Wall Speed: 12.5 mm/s Inner Wall Speed: 25 mm/s Top/Bottom Speed: 37.5 mm/s Travel Speed: 187.5 mm/s Initial Layer Speed: 20 mm/s And all my problems seems to be solved. Thanks for everybody in this topic. I tried to share everything I learned meanwhile. So cheers!

According to the comments on this YouTube video: It seems that if "Compensate Wall Overlaps" option is enabled Cura will totally ignore the "Maximum Resolution" setting and it will generate a ton of 0.01 mm moves. You see, when the "Maximum Resolution" setting is ignored the control card catch up the printing speed and the printer needs to stop or slow down a little bit. Also, I followed the suggestions on this video: It helped a lot. But in my previous post I showed the result out of his suggestions (changing baud speed, increasing buffer in Marlin and slowing outer wall speed). You see, that Cura is still behind Slic3r in quality. What interesting is that, I remember the first time I printed the 3DBenchy, it was excellent. Then I remembered that I printed it from the SDCard not from OctoPrint. So, it really seems that the source of my problems with my 3DBenchy prints are all about the high detail that the control card can not keep up with. And thinking that the same file resulted a smaller G-Code with Slic3r also makes me think that Slic3r is cleverly removing details. Here they are talking some kind of clever simplification that will keep the curvines of the edges while simplifying the data: https://github.com/slic3r/Slic3r/issues/3888#issuecomment-298214369 Now I updated the Firmware reintroduced the SDCard functionality, will update the firmware and print the same file from SDCard. I'll report back my findings.

It seems that setting the Z Seam to Shortest helped in removing the spiky Zits. But to reach the smoothest outer wall on curvy surfaces, the real gain was on setting the Outer Wall Speed to 1/4 of the Print Speed. And If you want to keep the total print duration the same you can also increase the Print Speed to compensate for the slower Outer Wall Speed. So changed my normal settings to: Print Speed: 75 mm/s (from 50 mm/s) Infill Speed: 75 mm/s (from 50 mm/s) Wall Speed: 12.5 mm/s (from 25 mm/s) Outer Wall Speed: 12.5 mm/s (from 25 mm/s) Inner Wall Speed: 25 mm/s Travel Speed: 187.5 mm/s (from 150 mm/s) The total print time was around the same. Also, I tried using Slic3r. Man, it printed faster and absolutely better. The outer walls were excellent. Will keep using it for a while.

Hey @campervd thank you for your tip and @Brilliant_Name for your vigorous efforts. I had the same problem (very consistent zits), were printing the 3DBenchy over and over again (at lest a part of it) you saved me a ton of filaments 👍 thank you!
