Olsson Block installation woes -- old nozzle won't loosen

Recommended Posts

I recently purchased an Olsson Block for my UM2 (and am really excited about it!) but in disassembling my printer for the new nozzle, I ran into trouble with this step: https://ultimaker.com/en/support/18016-disassembling-the-hot-end

Specifically, the hot end did not drop down. It is very much stuck to the isolator. I have turned it as much as I can, but am now leaving marks and deformations on the isolator by trying to turn it more.

What can I do?

Also, as a side note, I was looking for a PTFE ring to remove, and it appears there isn't one: I can't find it anywhere. Is that cause for concern?

Latest UM2 had a spare stainless steel coupler as a spare part with them. That is probably the easiest way. Otherwise try to unscrew it HOT and some people also used WD40. If everything goes wrong you may get a spare stainless steel coupler from your Ultimaker dealer/distributor or maybe more easily from 3dSolex.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
