  1. Hi Guys,

    I've tweaked and tweaked, but I can't seem to get quality past this...

    EDIT: My web server is not allowing hot linking of pictures, so here's a html page with the 2 jpegs:

    http://radiusdev.com/tachyio/um/ultimaker.html

    When you look at the profile of the printed model, the surface looks really smooth. Yet when you look at the model directly under bright lights, you can see this undulating pattern. My guess is that the printer wobbles as it prints, or that the x-y accuracy is rather poor. Also I still have problems with printing overhangs...

    I currently used netfabb to print this model, using standard quality PLA material settings, at 0.15mm layer height and 300mm/sec jump speed to reduce stringing. But I don't understand, despite this teeny teeny layer height, I can still see the layers! :(

    Additional info: Marlin firmware flashed from replicatorg 26, temperature was 185C to 200C...My extruder head jams often as well, every 2 prints...balanced the peek and bowen many many times. I am just thinking to myself that Ultimaker should have designed a snap-in-place extruder head...so every time it jams, we snap the old one out for cleaning and snap a new one in for the next print - kinda like the old days where standard 2d printers kept getting their heads clogged.

    Sigh, any help would be much appreciated...If this is the best the Ultimaker can do, it leaves me wondering how the promotional pictures look so good...
