UM2 extrusion problem

Recommended Posts

Hey guys,

I have just bought an ultimaker 2 off someone who has used it on and off for 6 months or so and it looks like it's in good condition and they assured me it was working perfectly. I brought it home and immediately changed the filament from ABS to PLA. I have attempted to print my first object but I noticed that there was no filament coming out onto the bed, the bed was set to 60 degrees and the extruder head to 220 degrees, I slowed down the speed but the filament was barely being squeezed out and not sitting on the bed. I aborted the print and scrolled through deciding to press restore to factory settings (regretful decision) where I calibrated the bed level etc. and then when I got to loading the filament and it began to try and extrude after heating the nozzle hardly anything came out again and the gears sounded like they were labouring and getting really loud so I flicked the off switch. What can I do from here? I can't turn it back on without starting the calibration process again. Is it a problem with the nozzle?

Thanks in advance

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
