Hello, how would you judge the quality of the first layer in this print? It’s a Coffee Stencil of sorts that I made into a 1 layer base surface so I can redo layer calibration and still be left with a somewhat useful object. Next iterations should be improvements on the print quality and they will have different designs so I end up with a collection to use on the Saturday morning latte 
How would you try to adjust settings to get better first layer in this case? Is it under-extruded? I could take a picture from behind a magnification lens to get a better view of some lines that are somewhat lower than the darker ones you see in the pics, yet this is a 1-layer thing :-/ …
I’d say it looks pretty good.
looks good, I would suggest to make layer half height so you can use 2 layer and use different pattern - one concentric and the second lines.
Can’t speak to those small circles showing up but it looks like you’ve got that 1st layer set to extrude at 150-200%'ish cause the lines look pretty fat and heavy. The mindset is to use that extra extrusion to help with 1st layer adhesion, but maybe dial that back a bit (125%). If you do decrease that first layer setting you’ll likely have to recalibrate and lower the printhead as well.
Also as someone suggested perhaps scale the z height to get another layer or so.
My 1-Layer “thing” was on purpose to be able to inspect the end-result, if I make it 2Layers wouldn’t that hide any FirstLayer errors that I might get a chance to resolve? In Slic3rPE The first layer is set to 0.2, the same with other layers, infill was set to 100% (but it doesn’t matter on the first layer anyways), Fill Pattern is Rectilinear, Extrusion Multiplier is 1, Temp for 1st Layer is 215, Bed is 60deg for PLA … what else could impact the way it was laid down? Ah, the Z adjustment could impact this the most I believe, that is set at -0.350.
@Florian_Ford there should be a setting for linewidth if you like a finer pattern…
@Ulrich_Baer I don’t mind a fatter, thicker, fuller pattern but I aim for consistency. In my pictures you can see some lines are lower than the others and that puzzles me.
@Florian_Ford are you sure they are lower? Because if the Bed is even and your Head parallel - you cannot get a lower layer without moving Z - you get fatter and thinner lines (or no clean line), you need to grind them to see if they are lower, or use a blade on top and see where light shining through the chink (lower). But i agree they look different yes. Do you print on glas (even)? Also you can check the g-code http://gcode.ws/ for irregularities, also a concentric pattern could change the result. If you print .05 layer you will see much more irregularities - or print 0.3 layer which is more forgiving.
Here’s my thing on thingiverse, I willtake a look at the .gcode file (also attached to the thing) as you suggest: https://www.thingiverse.com/thing:2918539/#files … maybe you spot something (I believe the .gcode has all the printing parameters in it too, right?)
There are some … just put the gcode in that webpage and you see it. The difference in the pattern is already in your Gcode. Seems you use relative extrusion this can cause that. Maybe try absolut extrusion.
Also wondering what Layer 3 does as there is a lot of travel movement but layer 1 and 2 are empty inside - this is strange.

… Just run the STL through my slicer and it came out clean (but i use cura and different settings). So I assume it is a slic3r issue.
@Ulrich_Baer Hmm, I don’t see any inconsistency with the tool you reccommended. [Edit: Ok, I see now in your print screen … I didn’t see anything unusual in the tool … strange that Slic3rPE would do that :-/ ]
@Florian_Ford in the tool … make sure to show mm³/sec (volume) in 2D Render options. The lines are indicating different speeds - which is not automatically bad - but with PLA it leads to different optical properties (see velocity painting)
@Ulrich_Baer Is this something I can prevent in Slic3rPE? (the velocity paiting thing)… that is pretty weird that a slicer would make inconsistent surface for the same movement -ex while filling a shape… Funny thing: I installed latest Cura and it seems I can’t use it because it requires WebGL2.0 and my Lenovo L560 laptop doesn’t have a video card that can take that 
… more tools to the clouddddd
i am not familiar with the actual slic3r but probably there are acceleration and jerk - you can deactivate them and check if the gcode looks better within the analyser (no need to print) - to be honest i would assume this is a bug, maybe this changes if you just turn your object a bit so the pattern direction changes and lead to a different result … I just had an slicing error in cura and only moving the object to a different position solved it (but in that case the stl was not clean)
ok, it looks like velocity painting it is (unintended this time) because I am printing another project atm and paused after the first layer was laid down and got about the same behaviour. I wonder if the top layer will sport the same characteristics … at least then I could make a nice pattern for it to print
