Completely understand and agree, just putting it out there for anyone whose willing to try.
This “Mojave Breeze” build does use 100W 24Vdc, not AC mains, which in one way is safer, but in another way more worrisome since it implies its using the Zero’s 24V PSU, which is only 150W in total (its generally light on instructions, which is also worrisome). That Ali page also offers a 24V 70W; either way it should be powered externally.
I can’t actually find any reference to how much heat the official heater puts out!
You should also review this older thread which covers many of the same topics including some pre-heating macros with additional fan controls Chamber Preheat - #29 by bircoe In it 50W is described as pretty limiting, only getting into the high 30s… So either 70W or 100W is plausible.
Any luck with getting your bed above 110°C?
