did you solved it?
I don't know the thickness of this 3D Solex TF2K... I'm using TFM coupler, tested with and without the spring. Gr5 made a spacer if you don't want to keep the spring. I actually doen't know if UM2+ have this spring above steel coupler. My gap between TFM coupler and steel is exactly 2.4mmEdited by fergazz
change gap distance from 2.3 to 2.4mm
I managed to find Ultimakers guide via google;
I guess I overcomplicated things when I started measuring the depth in the steel coupler to the "ledge" that starts before the threads end, looking down in it from above. Then I measured the length of the part of the TFM coupler that goes into the steel coupler and Houston, we have a problem. I wrongly assumed that it would be sitting tight all the way down against the "ledge".
In my confusion I also wondered how long are you supposed to screw the steel coupler on the heater block.
To make things more complicated I had the 3D Solex TF2K thingy, that is longer than original TFM coupler making it impossible to use Ultimakers above mentioned guide because you have to unscrew the metal coupler the same length that the TF2K is longer.
Please correct me here if I'm wrong!
What a mess but now it's time for a test run with my baby ❤️
