Hi again, sorry about all the delay, i'm still not having any luck. I'm definitely out of my depth, although i havent tried calibrating yet (mainly because on the link yellowshark suggested the first test was for a .5mm nozzle rather than a .4mm like the UM2, although being the massive noob that I am, i wouldnt know if that really makes a difference). Anyway, here are some pictures of the failed prints, and settings in places where i can remember what i used. These were the first 3 prints, the middle one was printed at 0.2mm i believe, and one has been printed at 210, one at 200 and i think the other might have been 230 but its anyones guess which was which. I think I printed one at 30mm/s and the other two at 50mm/s. This next one was printed with a lower bed temp of 60 degrees C, the bottom is still a bit iffy. And these ones were printed all at the same time using illuminarti's suggested settings. They looked promising at the beginning but then they came out quite rough. I'd really appreciate any more advice Thanks!

I've just tried lowering the bed temperature but it didnt seem to help, I might try it with a cold bed now. Thanks jonny, i'll try that and see. I'll also try those settings yellowshark has suggested. One question though, how do you use different settings for different layers? thanks a lot guys

Hi, I've had my UM2 for a month now so i'm still relatively new to 3d printing. I'm trying to print this voronoi chess set as a gift: http://www.thingiverse.com/thing:182824 but every time I try, the bottom half comes out looking very messy, it just looks a bit clumpy. I've tried a slower speed, higher temperature, lower temperature, different resolutions (0.1 and 0.2), but every time the lower parts look very messy. Im printing with white PLA. Im also printing the model at 0.4 times the original size because the original model is huge for a chess piece. I'd really appreciate any help? thanks
