Printing problem. Plugged nozzle, bed height or ???????

[jrm7997 0]

Good morning

I've done some research on this and am getting better at figuring out this machine. I have a stock Ultimaker 2 and have about 10 hours of use on it. I am using PLA.

My problem is that the size of the extruded cylinder of PLA is very small (picture attached) and if you look closely there are times it looks sputtered (?). When the PLA comes out of the nozzle it comes out on an angle. It kind of curls out. I have done numerous atomic cleanings and readjusted the bed twice. My research here and on the pictorial "problems" doc don't show what my printer is doing.

Am i right to think this is a plugged nozzle? And are my clues to this, the thin extrude and or the direction the fluid comes out the right way to be looking at this? I would think the PLA should squeeze straight out of the nozzle.

Thanks in advance

Your first layers looks way too squished. Realign the bed caibration. Also, if the filament extrusion don't make a spaghetti when priming before the print, maybe there's extra preassure on the hotend. If you didn't touch the assembly try atomics. If you did tight the screws (four on the hotend upper part) with the bowden 'on' you might be making the bowden to compress too much. If so, take out the bowden clip and reinsert it normally and close the bowden with the clip again.
