I have a P1S.
A few months ago, I had a meltdown of my print head, not sure why. But BL promptly sent me a new nozzle. They didn’t need to though, as I had bought a hardened one for CF when I bought the printer, and so I put that one in, along with the hardened gears, etc.
The thing I loved most about the printer was that I didn’t have to leave clearances between pieces in my drawings. Everything fit with perfect tightness. PET parts complained a bit, but PETG were perfect. I printed a bunch of multi-piece objects, and they all tesselated perfectly.
However, after making the upgrades to CF-ready equivalents everything is a little too tight. PETG parts have to be filed down to fit, and sometimes still break, and PET is impossible.
I looked on the forums here and found lots of solutions, but nobody talked about an effect from changing the head, which I think would affect which solutions might be likely.
So if anybody can suggest some setting or alignment procedure to improve this situation, I would be extremely grateful. The printer is otherwise working just like before, which is to say flawlessly…
