Cool, thanks so far guys. I am currently printing off another robot having altered a few settings. Bed temp 50 Print temp 200 I also tried to alter the fan speeds but ran into issues, i couldn't find an obvious place to change it in Cura (14.07) but i may just be missing it, i have found the 'Tweak at Z 3.1.2' plugin and that seems to give the option of setting a new fan speed, so i se that to 'Z height to tweak, 1mm' and 'New Fan Speed, 255 (0-255 scale) but i noticed that according to the LED display the fan as still very low <25% up until around 5-10mm. I have noticed during the first few stages that some of the edges are still curling up a little on the right (not on the hotbed, on top of the print) and some of the bridging looks maybe slightly worse than before. I will post a picture or two when it has finished!

Hey Guys, I have been having a small problem with my Ultimaker 2 and i was wondering if you could offer some assistance. Quick background, got the machine last week done a couple of test prints but i have run into a small issue. Overall the prints have been great and i have been majorly impressed but i have noticed a small issue. On the right hand side of the prints there occasionally crops up an issue in areas that require support..or building out from the edge. I first noticed it on the Ultimaker robot default file, the right hand 'ear cup' has some flaws. Image 1 - Left ear, fine: http://imgur.com/N9khP4Z,Dp2AhfN#0 Image 2 - Right ear, not fine: http://imgur.com/N9khP4Z,Dp2AhfN#1 I assumed this may be an issue with the file (silly me) but when i started another model today. Here are some WIP that shows the same defect creeping in. Album showing problem: http://imgur.com/a/Uyy48 As you can see the left most fin is perfect, crisp clean line but the others have a slight wibbly section. I am unsure how to proceed, being relatively inexperienced. I thought maybe supports might help but then having one fin fine seems to go against that logic. Having finished the model i can highlight the defects in more details. Pictures in this album: http://imgur.com/a/AK6mU As you can see in the first two images the bit at the top of the fins (printed first as upside down) there appears to be a major issue that is not present on the other fin. We also see some excess flash and almost laddering on parts of the vertical structure. Observation during printing showed that this excess was in the place where the printhead stopped and started (i.e. it would do a loop around and the start/stop point of the loop would have the notch on the side) I am using standard settings: PLA 2.8mm 0.1mm layer height 0.8mm shell thickness 0.6 Bottom/Top Thickness 15% Fill 50mm/s print speed 5 sec minimal layer time cooling fan nozzle temp 210C Bed temp 70C Any help would be greatly appreciated. Also as a side, anyone have any amazing tips for bed levelling other than the eyeball/paper guess work method. Many thanks. Josh
