@fcwilt "*if cost is an issue than 3D printing may not be something for you to invest in.
The amount of money I have spent on filament dwarfs the cost of running the printers.*"
Hehe yeah, that's probably right, but I'd rather save on power than on the filament
"*I suggest you follow the advice to connect both to the board via the SSRs and use a separate temp sensor for each one.
I would also suggest you re-consider using line voltage units.*"
I suspect when you say "connect both to the board via the SSRs" you mean to do it a different way than the one I laid out in the original post? Could you please elaborate on how I would go about doing that?
Is there a line voltage unit you could point me to for 650W heated beds?
Sorry for all the questions, this is my first build...
