Hey all, having an issue where my drive wheel in the back of the printer is slipping and/or losing traction. I presume there is likely a simple fix, but it has alluded my my limited understanding of the design. Is there some kind of adjustment that can be made? I am using 2.85mm PLA filament on an Ultimaker 2 Happy Friday and thanks in advance!

I have been running into a problem of the nozzle remaining on the print once it has completed the print. Leaving a big ol' blob of PLA on my print. I presume there is some nifty trick or GCode that will command the nozzle to return home after the print, if I am not around to do it manually! Hope someone knows the trick! Thanks again (in advance) to anyone that takes the time to help me out!

After opening up the mother board panel and carefully labeling and unplugging the wire harness for all the nozzle wires and cables, I was able to reattach my repaired and reinforced upper nozzle piece. I will print another one while the apparatus is functioning. I used a slim piece of G10 ( I'm a knife maker and I had plenty laying around) to give some extra support to the repaired piece. The 3M scotchweld plastic and rubber glue is quite strong but I didn't want to risk it! Thanks for the support all!

Hey all, I'm a long time admirer of 3d printing and have been dabbling in 3D design for a couple years now. I was just given this old(er) Ultimaker 2 and was happy to see that it basically started right up after being used a few times and shelved. I noticed this top piece of the extrusion head had some cracks and obvious damage, but it was hard not to try and print something. After a total of maybe 3 hours of printing since I received this printer it finally broke, obviously 75% into a print lol! Just wondering if anyone knows what its called, where I can get a replacement and perhaps some detailed diagrams of the entire machine so I can correctly identify parts on my own! Gonna try to use some plastic welding glue to see if I can get some temporary use out of the machine! Looking forward to exploring the collective knowledge here in the Ultimaker Community!!
