jameshs - whenever i remove the nozzle that way I seem to damage the heater block with the pliers over time. I know the solution would be to grip softer, but sometimes it takes work to get a nozzle off, at least for me! Also, where did you get the needles from? And does the atomic method work the same for the UM1, as what I've read has been mostly for the UM2? I ordered all my filament from Ultimachine. It seemed to be of good quality. But what other suppliers do people trust and use to avoid clogs? Finally - and I know that this has been a long post already - it seems as if my UM1 Z-axis q

The only way I've managed to do it is to strip a copper wire, wind a few strands, heat up the nozzle, and try to poke the wire through, but it does not work very well. I bought some 0.4 mm drill bits awhile back, but they kept breaking off inside.

Oh here's a second post so I can receive messages.

Ok, so here's the basic question: I have a UM1, and I want a new, better printer, but I am worried the UM2 will have the same problems my UM1 had. I got my UM original about a year and a half ago. It worked very well at first, but there were plenty of issues. Z-screw leveling issues, bowden tube-popping issues, belt tension issues, extruder issues, and primarily under-extrusion / nozzle clogging issues. Oh GOD, the nozzle issues. The improved somewhat when I finally printed a filament cleaner, but after X hours of printing (which good, expensive filament), they would inevitably come back. I
