Hi, I have printed some nice objects before, but mostly small. But now I made a larger prototype and have some questions about the result. I hope someone is willing to have a look on the pictures. (Printing quality is set to 0,2 because this is a prototype.)
The top layers aren’t finished smoothly (bottom is ok);
The planes parallel to the axes printed rather well, but if not parallel there are very visible layers and some vertical edges.
Earlier, I already did the Wiki xy-carriage alignment and the printhead moves easily, the belts are parallel, etc.
The only thing maybe is that some rods can move about 1 mm in longitudinal direction. When assembling, some rods were to long and I had to grind them shorter. Could this be an issue?

How many top layers do you print?
Seems that the top layer is actually the last layer of the infill.
Well, then put that in the cura engine settings and try again.
Maybe get the uptate to repetier host 1.5.0 that recently came out.
It contains newer slic3r and cura engine models.
The nozzle diameter under the tab extrusion is set to 0 (and says ‘0 = use value from printer settings’) In printer setting the nozzle is set to 0.35. So I don’t think this could be the issue?

I found on my k8200 that somtimes didn’t work correctly.
At least for the 1.0… repetier versions.
Don’t know exactly why.
Indeed I think too the top layer matter has to do with the settings. (I did check all hardware calibration.)
I use Cura. Did you find any solutions? Which settings can I try best?
Made another print with different settings. 5 deg. more temperature. Top/bottom thickness higher. Infill overlap… The top finish is somewhat better but not perfect.
I am still very sad about the shell. Although the edges are not the same as on the earlier print, it isn’t good enough.
It seems that my prints are less good-looking then before the xy-carriage aligment when they were moving rough.
Could it be that the clamps has to much backlash now?
Thank you SlowFoot.
You mean that my expectations are to high. Maybe, I made some nice prints (picture, btw layer height 0.1) with a very fine structure before, so maybe I am spoiled
It seems that the problem occurs when printing between the x and y direction and changing angle. If I make a clean circle, it prints nice.
If I recognize this as inevitble, I can focus on the top-layer finish, the other problem…
I am testing different Cura settings with the same object to get a better shell and top layer. I get good results for the shell but the top layer results are still dubious. I tried several setting for this, but the differences are very small. Only layer height 0.1 vs 0.2 seems to make a difference.
Given that the shell in 0.2 is excellent and I’d like to print fast (who won’t) I am wondering why Cura doesn’t offer last layer settings to fix this problem?
Can someone who is using Simplify3d tell me whether this slicer has last-layer settings so the top surface can be manipulated?
