zark, you're initial assumption is correct. As there's not much information in the EScribe manual, and this is my first DNA mod and there's a lot to learn.
And on 250C chipset there's no boost setting under preheat when running Temperature Control mode. Only Punch, Watts and Temperature. And preheat Temperature is limited to 149°C or 300°F, and yet again there's no information in the manual that is really useful.
But on a positive note, changed to a 6 wrap SS316L 25 AWG (0.68mm × 0.27mm) flat wire coil at 0.32 ohms, increased power to 30 Watts. And are now reaching approx 240°C, so getting closer.
But it would be nice to have a fully updated manual for EScribe, with a full and not cursory description of all options and settings.
