It won't stop extruding UM2E+

Oh wait I figured it out.

 

Okay well the filament isn't sticking to the glass.  Is the glass bed warm?  check that with your finger.  Also put a little glue stick on the glass and spread that with a wet tissue and wait for it to dry.

 


But most important the nozzle is probably too far from the glass.  Try pushing up on the bed while it's doing that and the filament should start sticking to the glass.  If that works then turn the 3 leveling screws counter clockwise (to move the bed up) an equal amount.  Maybe a half turn.

    Alright so applying glue worked but theres another problem, the fillament wont stop extruding out so when it tests the filament in the nearest left corner it drags that filament to the actual print

    It's supposed to extrude into the air at the start of a print. I usually grab it with tweezers to keep it from dragging once the purge is done. The purge makes sure you have a good clean flow of filament when your print starts.

    What? My Ultimaker 3 doesn't do this, wouldn't the printer retract the filament?

    The UM2+ does the purge as part of the UM2+ firmware. You could override it with a different slicer, but if you're slicing in Cura, the firmware is going to proceed as normal with this purge.
     

    The UM3 does a priming blob at bed level (it should stick) as part of the gcode and settings in Cura. You can also turn it off in Cura. (Check boxes for Enable Prime Blob.)

    Oh so I have to enable the option so that it can stop extruding in cura when priming it?

    For your Ultimaker 2+...it's built into the firmware. Unless you use a different header/manually write gcode that overrides the firmware, it's always going to purge like that.

    On the UM3, it purges, but differently, and the purge is controlled by Cura, so you have the option to turn it on or off for each print when you slice the file.
