I’m not so sure about that. I have gone all-metal (and bimetallic) on my 3V2 for the, uh. The bit connecting the heater to the heat sink. The HEATBREAK. Right. But the heater block, sensor, heat sink are all original and they have absolutely no problem with 1.0mm, at least up to 220. I’ve done various power measurements and it’s not having to work hard to do it, either.
The other changes I’ve made to the hot end assembly have been adding more cooling, not more heat. (It’s dual fan now and has better airflow to the heatsink.)
I mean, it could all be due to the bimetallic heatbreak. But, well… 1.0mm is 100% absolutely fine on my 3V2.
