PS: also you can play with perimeter/infill overlap parameter in your slicer (slic3r and Sliplify3D have this option, don't know about Cura).

I will redo my extrusion width calibration. Then I'll reprint the part. It is still fairly solid though.

Looks like underextrusion. Did you calibrate your extrusion with? If so, probably you did it at at much lower speed. Probably the speed was too high for this print.

Yeah, Cura has infill overlap setting that, too. Its to be found under the "..." section of infill setting.
@Captain: Tbh you started with the correct upgrade. For me, having a zero x/y offset probe was one of the most important steps to get the printer working more reliably. Use dc42/Escher calculator to dial it in and you should be much better off.
2nd next big improvement for me: Glass bed on top of the aluminium. A bit of hairspray and you will have a lot less issues with the print not sticking to the bed. Also, the glass bed is "plainer" compared to the aluminium, which makes the results of dc42/Escher calculator more reliable.
About your print, I agree with paul: Dont sweat it, should work just fine. And it does look like under-extrusion. Maybe your filament diameter varies? Cheap filament? I had similar issues with Velleman brand filament (1.65 mm ... 1.78 mm diameter variation - abysmal print quality).

Is a glass plate really worth it? I've been pretty happy with my aluminum plate... I just put some blue tape on it and everything sticks like crazy and the bed heats up quickly. I have noticed I don't even have to be careful with the tape -- it gets cut or scratched, but until it starts looking like swiss cheese I still get good adhesion and a smooth bottom surface. And when it *does* look like swiss cheese, I just rip off the offending pieces and put new ones down.

I have great adhesion with my aluminum bed as well, but it's just got imperfections in it causing half of the bed to be lower than the other. So larger prints would be hard to print.

What firmware are you on? Repetier supports bump-mapped Z correction, which mitigates the unevenness by quite a bit. The surface in contact with the bed might be off slightly, but the print head will always be the same distance above the bed.

I'm using Repetier... That sounds just like what I need, do you have a link by chance?

Thanks, when I get home from work, I'll check this out and hopefully I can smooth out the bed.

You'll need 0.92.8 to use this feature IIRC. I installed the latest version, and it looks like in the latest version they have fixed their bed correction to normalize at (0,0) and give you the output at G33 commands, so my app is no longer needed for migrating the data when you change z height.

Is converting from 0.92.6 to 0.92.8 just a matter of flashing the board and re-entering the previously stored EEPROM values?
Have you had any issues with 0.92.8, or is it pretty stable?

In theory you can import your config with their web tool. In practice, you'll need to recreate your config based on your current settings. I wouldn't count on being able to import the EEPROM values, so make sure to use your latest values when creating the new config.
I had a number of issues with the previous version. They're still calling it 0.92.8, but it looks like they've fixed most of what has been bugging me about the previous 0.92.8 release. They really should increase the version number when they release a new version..

Just as an FYI for those of you out there not running Repetier, I'm now using Craftware as my slicer/gcode engine.... It's pretty smexy and highly configurable, way better than pronterface. Allows for custom support placement, live update previews of changes you're making to the code (shells, infill, layer height, etc.). Has every option for customizing your printing.

That looks like some pretty good software. Why didn't you recommend it to those who use Repetier? If you don't mind me inquiring.

I don't know much about Repetier at all as I can't get it to install on my computer, but what I've heard from reading the posts here is that it might get used for updating the firmware? If so, then this can't do that. It's just a slicer/gcode creation program that's pretty user friendly.

@Captain_Tim and spiffcow: Whatever sticks. ;D I didn't have as much luck as you guys with my aluminium bed. Glass bed has some advantages and disadvantages to my experience: Bad: Heats up WAY slower, reaches ~ 105°C max. Good: Waaay more plain compared to my aluminium bed, which makes the job of dc42's calculator quite a bit easier. And sturdy as hell. Cannot scratch it a bit.
I use hairspray method. But if blue tape works, imho stick with it (pun intended). I got a 220 mm diameter glass bed of aliexpress for 15 bucks. For that to fit I had to countersink the screw holes in my aluminium bed.
Just a remark on bump map: Yes, it does work *to some extent*. It will help to overcome deviations of +/- 0.2 mm, but not so much more. If you still run into problems, try to increase the height until which the correction is active (DISTORTION_END_HEIGHT). At 2 mm, that worked out quite well for me.

I've tried all sorts of bed solutions:
ABS slurry: Stinks to high heaven, PITA to get off the remnants, didn't like at all.
Glass bed: Doesn't conform to the heat bed, so possible air gaps which will slow down heating. Prints stuck OK. Didn't like that I had to clip on and off all the time. Nozzle head hit clips sometimes on large prints.
Blue painters tape:
3DXTech brand: was sent a 100mm (~4") wide roll for free after buying a bunch of filament from them. Stuck like crazy for PLA to the extent that I couldn't get it off of the print.
3M Blue tape: Second most favorite surface. PLA sticks great, sometimes too well. Leaves "bumpy", matte finish on print.
Polyimide tape: Most favorite surface. What I use all the time with ABS/PLA/PETG (basically everything I print). It can be a PITA to get on the bed (I use the 200mm wide stuff from Folger) but once it's on, it lasts forever unless you gouge it up with your nozzle. Prints will just pop off, especially if the bed cools down.
Tricks: To get on, unroll enough for bed (you might have to stick a little on the bed so it doesn't get stuck to itself), spray the bed and the sticky side of the tape with water. Carefully lay it down from one edge to the next using a squeegee (I use a credit card) to push out the bubbles. Since the bubbles are water and not air, they will be easier to push out. Leaves a smooth, glossy finish on print.
Also, when you go to print, heat the bed to a minimum of 40-50°C and clean with a liberal amount of isopropyl alcohol.
The only downside I have with the Polyimide tape is that I sometimes I have to use a skirt on the black filament I have as the corners might curl.

@Professor:
Looks fine to me, honestly. I would still suggest to use the GUI to set your configuration.h up: http://www.repetier.com/firmware/v092/
It's just so helpful. Look out though: If you changed variables manually using Arduino GUI, you may have to re-type them in the firmware tool.
