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
