Here is the Beast
it's one of my DIY projects, I had designed it with a biqu board + DM542 drivers for all nema23 motors.
It was noisy and not great .. So I decided to put a Duet 6HC + 1LC in SBC and hopp no more need for any driver, the 6HC manages all the motors by itself (1X + 1Y + 4Z)
In addition I had fun adding instead of the single heating mantle of 2000W controlled by a useless external thermometer, 4 silicone plates of 500x500mm and 800W each, and thanks to the 6HC I can control them one by one, like that no need to heat everything and eat 2000W for nothing.
All 4 heating element work in 220V, controlled by one 24DC 220AC SSR eachWhat do you think
