if i want to use qu-bd thermistor what values do i need to change ?

Have to use lawsy's firmware, and its type 80.

Removed stock SD silicone heater from bed, replaced stock z screw to 5mm, soldered heater bed reinforcements to board and ordered 30A power supply and cut and drilled to acomodate qu-bd hump.

if i want to use qu-bd thermistor what values do i need to change ?

also two qu-bd's 200x200 12v ordered

external temp controller feels like a great idea .... wonder if they have units with two thermistors ?

If you are dealing with high voltages/amperages it can be dangerous. Proper SSR should costs 3x more, and from what I understood they also need a beefy heatsink unless you're switching a couple of amperes.

and control it using this: http://www.amazon.com/AGPtek%C2%AE-Univ … controller

with this: http://www.amazon.com/Crydom-TD2410-Zer … lay+crydom

and the sensor of your choice. You can re-use your thermistor, or get a $5 thermocouple: http://www.amazon.com/Type-Flat-Thermoc … ermocouple

PID learning control puts firmware solution to shame, plus eats up less processor time. 800 Watts and a little wiring. But a more solid solution.

but my printer is trying to piss me off ... since yesterday the bed maximum temp reached 69c and thats it ... any ideas ?

So i have to come up with double bed solution sooner than expected.
two qu-bd's maybe and separate power supply for them and solidstate relay ?

ebay has also 200x400mm 220v silicone pads available .... but 600w .... nice and toasty for sure big_smile

Do you need to heat it up faster then this?

Recieved new rod's ... all are bent  about 1.3-2mm ( packaging was ok ) sad

China FTL sad

might have to source from mcmaster. more expensive, but at least they have actual precision ground hardened rods instead of just chromed mild steel hardware store rods. and they know how to ship them.

I personally think that multiple heating pads are the best option.

But i give You 5 points for thinking outside the box wink

update on the SD XXXL front - still waiting for rods to arrive sad
