Problems with top layers Hi everyone I'm having issues with the top layers of my print not being solid, i have tried to sort it myself by measuring the filament and have solid infill (even though there are still gaps) but no matter what i change i cant seem to get the top layers to be solid as you can see from the picture Any thoughts on what i can try would be great I'm running a prusa i3 with 1.75mm ABS printing at 235 degrees C with solid infill at a layer height of 1.480mm using Rectilinear infill for top/bottom/infill using slic3r and repetier host Thanks in advance Chris https://reprap.org/forum/read.php?4,288372,288372#msg-288372 Fri, 07 Aug 2026 07:47:55 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,288372,288845#msg-288845 Re: Problems with top layers https://reprap.org/forum/read.php?4,288372,288845#msg-288845
It's the only way I have been able to get slic3r to work with my machine, running a 0.25mm nozzle.

During beta releases, there was a version that world print correctly and with the next beta the print had the passes spaced too far apart just like this print issue.]]> Dirty Steve Reprappers Fri, 03 Jan 2014 21:42:45 -0500 https://reprap.org/forum/read.php?4,288372,288843#msg-288843 Re: Problems with top layers https://reprap.org/forum/read.php?4,288372,288843#msg-288843
It's a decimal number adjustment such as .92, .95, 1.01, 1.05 as examples.

Run single wall cube calibration prints from Thingiverse to find your adjusment.]]> Dirty Steve Reprappers Fri, 03 Jan 2014 21:37:59 -0500 https://reprap.org/forum/read.php?4,288372,288821#msg-288821 Re: Problems with top layers https://reprap.org/forum/read.php?4,288372,288821#msg-288821

Dirty Steve
it looks to me like a slic3r auto-calculated extrusion width problem. Developer will not acknowledge this problem.

Under Print Settings>Advanced set default extrusion width to the same size as your nozzle, this will effectively place your extruder passes closer together.

You will need to adjust your extrusion multiplier for your manually set extrusion width.

Is it just me, or has this issue come up a few times now?]]> Yvan Reprappers Fri, 03 Jan 2014 19:59:51 -0500 https://reprap.org/forum/read.php?4,288372,288690#msg-288690 Re: Problems with top layers https://reprap.org/forum/read.php?4,288372,288690#msg-288690 matrix4721 Reprappers Fri, 03 Jan 2014 15:00:39 -0500 https://reprap.org/forum/read.php?4,288372,288603#msg-288603 Re: Problems with top layers https://reprap.org/forum/read.php?4,288372,288603#msg-288603

I would rather try to fix the issue rather than adding extra layers because i think the top layer will still look abit rough even with extra layers, i will double check the extruder calibration but last time i checked it when i told it to run 100mm of filament it ran 100.7mm so i think its pretty close]]> matrix4721 Reprappers Fri, 03 Jan 2014 07:14:31 -0500 https://reprap.org/forum/read.php?4,288372,288385#msg-288385 Re: Problems with top layers https://reprap.org/forum/read.php?4,288372,288385#msg-288385 lazzymonk Reprappers Fri, 03 Jan 2014 06:49:35 -0500 https://reprap.org/forum/read.php?4,288372,288372#msg-288372 Problems with top layers https://reprap.org/forum/read.php?4,288372,288372#msg-288372
I'm having issues with the top layers of my print not being solid, i have tried to sort it myself by measuring the filament and have solid infill (even though there are still gaps) but no matter what i change i cant seem to get the top layers to be solid as you can see from the picture

Any thoughts on what i can try would be great

Thanks in advance
