-I forgot to mention I am printing with the Silver Ultimaker PLA that came with the machine. I haven't changed the temperature setting so that should be the default of 210. I will give 225 a try. -I will also listen and watch for clicking. I haven't noticed anything yet, so I think this is OK. -If I go to the Advanced Settings, they are still on the defaults so the speed settings are (in mm/s): Infill speed: 80 Top/Bottom speed: 15 Inner Shell speed: 60 So these should all be set to 0 to so they use the same speed as the general print? Outer Shell speed: 30 So that could be set to less than the basic print speed (so set to 10 or 15 since basic print speed is 20)? Thank you for your help. -Dan

Hey Guys, First post here. I am working with a a new Ultimaker 2. Prints were going fine for a while, but I am thinking I now have a problem with under-extrusion. See below: Settings Were: Layer Height: 0.08 mm Shell Thickness: 0.8 mm Enable Retraction: Checked Bottom/Top Thickness: 0.08 mm Fill Density: 24% Print Speed: 20 mm/s Support Type: Touching Build-plate Nozzle Size: 0.4 mm Support Settings: Structure Type: Grid Overhang Angle for support: 60 degrees Fill Amount: 27% Distance X/Y: 0.95 mm Distance Z: 0.15 mm Can you guys confirm that this is an under-extrusion issue, and what I might be able to do to combat it? I have tried the Atomic Pull Cleaning Method several times recently after a bunch of stuff got melted to the nozzle and I was coming out clean. I have printed a number of times since then, but the under-extrusion seems to have started around that time, and slowly gotten worse. I tried another version of the print with thinner layers and 100% fill. That came out OK, but one corner curled up a lot and the overhang for the cavity in the middle on the underside was pretty rough. Any help or insight you can provide would be much appreciated. Thanks, -Dan
