I went back to the old firmware. Helped me fix the issue for most part. Changed the Temperature to a higher figure, Layer height 0.2; Speed 60 mm/sec.

Gr5, Here is the result of printing the test file at 230C When I first read your comment, I failed to notice you asked to print at 230C. So I went ahead and printed it at 210C first and below are the results. The images of blue test print were printed later and at 230C. What do you think is wrong with the print or the machine? I rained very heavily today (Non-seasonal). Do you think the filament has retained moisture? -Small

Thank you. That makes sense. I split the object to print and am trying to print it standing up. Again, just want to make sure if there is anyway I can add custom supports in Cura? If not I might just have to do it through my modeling software. Have you read any problems in printing after latest firmware 15.02.1 was updated recently? Best Small

Hello, I have to print a project that requires multiple prints of the same file. I have been printing it but having really rugged finishes on the bottom few layers (with support). 1) Is there a way to make changes of to where the support can be placed? 2) I used the angle (See cura picture) since I have limited time and material to finish the project and this is the most efficient angle I can print it at. 3) The settings I used were as follows Bottom Layer speed: 20mm/sec Bottom Layer Thickness: 0.6mm Layer Height: 0.1mm Shell Thickness: 0.8 0.8mm Normal Speed: 50mm/sec Temperature: PLA 210 C The bed level is checked before each print. Please let me know if any one has any suggestions on improving the quality of the print on the bottom layers where the net forms. The bottom layer nets are very clumsy compared to the front. Thanks -Small

Thanks for the prompt reply gr5! 1) Am attaching an other picture to show how the brim prints. Some lines of the brim are missing due to under-extrusion. The second picture was printed upside down where the bottom layer came out really bad. I relieved the bed, which helped improve the smoothness but there were still some rugged parts. 2) I use Cura default settings, that is bottom thickness: 0.6 mm ;Bottom Layer speed: 20mm/sec ;Layer height: 0.1mm ;Shell Thickness: 0.8mm; Normal print speed: 50mm/sec; Temperature: PLA 210C. Highest I have used lately is 210C because I have been print PLA for the past few days. 3) Yes I have used almost used more than half of the filament. What should I do cause it would be a waste to discontinue using the filament after using half of the spool? 4) Skipping happened while printing the brim and the first few layers. Not after that. Thanks for responding. Small

Hi, I recently updated the firmware on my Ultimaker 2 on 20th Feb 2015. After I did that, the brim did not print properly. There is spacing and under-extrusion in some lines of the brim. Please see attached picture. The finish of the print from where the brim is broken off is of very poor quality. See attached image. (the uneven part is the bottom in the picture from where I broke off the brim) The filament feeder is also skipping and making a clicking noise at regular intervals. I have cleaned the extruder head using the atomic method, as well as poking the extruder with a 0.3mm wire to remove debris. I opened and re-assembled the feeder box to clean and remove any filament debris. The bed is leveled and the filament I use is reliable colorfabb which printed fine in the past. Please help. I need to start printing soon to complete an assignment. Small

Thank you for responding. @Gr5, In the orange picture I did not attach a brim, but in my next print I attached a brim to the object but it still lifted on the right hand side. Please see attached picture below. I did level out the screw heads from under the glass top as you said. I think that helped with the next print. Also, do the X and Y rods have to be absolutely parallel? How do I check that with precision? The Y axis rod on the right side of the machine seems to be a little loose. I checked the rest and they seem to be fixed while the Y axis on right side pops out about .05mm while printing as the belt rotate? Is it normal or something I need to fix? How do I change the Bed Temprature? Is there an option in Cura? Lastly, I have started using aqua net hair spray for the prints to stick well. It works so far. I appreciate your help. Best, Small

I just got my Ultimaker 2 a week ago. I have been printing with both PLA and ABS. The prints on the right side of the glass bed seem to lift up. I have leveled, and re-leveled the bed. Made sure the level is right using the leveling app on iphone, used materials like Gizmo Dorks, Color Fabb PLA and IC3D ABS. Nothing seems to work. The settings I use while printing PLA are as follows: Print speed: 40 mm/sec; Fill: 100% (This varies and on different infill levels, the problem remains the same); Layer height: 0.1 mm; Support: Brim; Fan speed: 100 %: Bed temperature: as per cura standards. The brim for support prints great on left but has gaps on the right side of the bed. Eventually the print starts lifting a lot from the bed on the right hand side. Please see pictures attached.
