My 3D printer keeps stopping part way up the print
dpgtaylor replied to dpgtaylor's topic in Ultimaker 3D printers
Thanks for your reply. What is the small modification to improve this that you mentioned? Also is there a suggested way to clean the threads of the olsson block and nozzle? I have ordered an official ultimaker nozzle and want to make sure it is going into a clean thread in the heat block. Thanks -

Hi thanks Geert_2 your advice is very helpful. I have double checked the fan and it carries on running at full speed. I think the issue lies with the nozzle more than anything. Before trying anymore cold pulls I disassembled the print head and looked at the olsson block. There is a large amount of burnt black residue (as pictured) on the screw threads of both components. The coupler is completely fine as it is new. There is a large build up of residue inside the nozzle with some fairly big parts in there. I wonder if it is worth trying to clear the nozzle as it appears to be in a pretty bad st -

Thanks - I have dropped the temperature when doing the cold pulls and its giving me a better looking tip. I performed 11 cold pulls and tried to perform a print - it completed the print but under extrusion meant it snapped and was messy. I tried to print again and it was massively under extruding. I have performed another 10 cold pulls and this is what the tip is looking like. It shouldn't take so many pulls + it shouldn't look this bad after 10. Its not smooth at all - I know a new nozzle would solve this but not keen to just buy another and need the printer today. -

Yes I print PLA at 210 and at 60mm/s I believe -

Yes the middle fan is working, no issues with it -

I had recently been printing a run of the same 3D print file - and need to print a large amount more for a deadline. Unfortunately the printer stopped extruding part way through one of the prints. I went on to unblock the nozzle but noticed the coupler was completely blocked (as pictured). I then ordered a replacement coupler and installed it. I then proceeded to carry out 11 atomic pulls as pictured until it came out clear. This seemed to work and the first print I did yesterday since the atomic pulls came out clear. I removed the print and went to print the file again, when I came back -
Hi, One of the printhead fans (on the left) of my 3D printer has stopped working. I have checked the wiring and all seems to be fine. Has anyone found a UK supplier for a replacement, it seems impossible. Also I have read on other posts that you can replace the heat sink fan with a quieter model, but again I am struggling to find a UK supplier. All the ultimaker recommended sites don't sell replacement fans it would appear Thanks

Hi, I have been using my ultimaker 2 (recently purchased) with filamentive white PLA and its been printing fine with a few minor teething issues. I have managed to solve all of these and it was printing fine again. I did use white abs at the start but that was several months ago and I have printed perfectly fine since then. However, the nozzle now appears to be blocked and the atomic method just refuses to solve this issue, its incredibly frustrating as I really need the printer working as I am in my final year as an Architecture undergrad and everything has to be done from home at the minut
