I rarely have the need to change a nozzle...
in over 7 years, i think i have had all of 2-3 clogs...
I dont change nozzle sizes, so no needs there...
i dont run overly abrasive materials, so no need to change nozzles frequently there...
I also have to take issue with the non-replaceable thermistor... having to replace the entire heater setup is not cost effective to me
just not something i need.. but for those that do need them.. or just want them "because" - have at it.
]]>The evo system is built for the masses.
there are many advantages.
the wires are strain relieved so no worry about pulling one out. the ceramic heater is actually silk screen printed.
there is no aluminum block to melt in the case of thermal runaway.
the main advantage is the nozzles can be changed by hand, no tools required, and the heat break and nozzle are sealed and integrated.
So we're kind of coming full circle, back to integrated ceramic heaters/thermistors a la my late Printrbot's Ubis hot end, only modular and fancy as befits 2021. Neat stuff.
]]>why? But all of my machines save one were single-extruder, so perhaps there's an advantage here I just can't see on my own.
