help with top infill stringiness

I recently got my printer and I'm having trouble with the quality of my prints. The top specifically. I've noticed that both the top infill and top solid infill are coming out incomplete and stringy. I've tried adjusting a number of settings and followed some advice on the forums for similar issues. I've printed a number of test boxes but I cant seem to get a clean top. I've decreased the print speed for solid infill from 60-40, I've decreased the top solid infill speed from 50-30, I've decreased the hot end from (225,215) - (220-210), I've increased the extrusion width of solid infill to 200% and top solid infill to 300% hoping to reduce the stringiness. And increased the extrusion multiplier from 1 - 1.1. I even increased the number of top layers from 3 - 4 and changed the pattern from rectilinear to concentric based on advice from someone who was having similar issues. I've included a picture of all my test prints (in order newest to oldest left to right) and a close up of my latest 3.


Anyone got any further suggestions on what might be causing the issues with the poor quality of the top layer?

Ok. I printed from the g code. They are definitely printing better. The ones sliced by Cura look to be better, so I decided to print the test cube with Cura. Here are pictures of the 3 prints you sent me + the test box sliced in Cura. (Right to Left Slic3r cube, Cura cube, Cura test steps (program froze near the end), Cura test box)

I increased the top layers from 3 to 6 for the test box and its the best top I've had yet. Is this as good as it gets or can it be improved?

I'm considering getting an upgraded hobbed bolt. I think it may help compensate for the slower speed of cura

Thanks

 

What I think needs to be done is have it slow down and increase the feed rate and temp on the top solid infill. I did this manually and it turned out well. There aren't any direct settings for this that I can tell in cura, but I think I should be able to edit those settings in using g-code modifier

 

Savan, Looks like you are almost all set thanks to Jeff. Since you mentioned the hobbed bolt just check it every few prints and there should be no filament shavings in it. If there are it will eventually give you extrusion problems like missing segments.
