@phaedrux Thank you sir. Any more articles on wiring other components would be helpful if you know of any. Stepper motors, extruder, etc. This is very good one though that will help me with my bed design

@Phaedrux Thank you for the links, I'm definietely going to install a thermal cut out after all this discussion. Will read up more as well on heated beds and SSR

@MSquared Thanks for the drawing! I really appreciate it. I'm a very visual person so this is great for my understanding. I will make sure I'm 100% confident in my circuit before doing. Will read up more as well. Might reach out in the future with questions!

@msquared

Thanks for the relay link. Is there any documentation on wiring a bed with a relay to the duet?

My next question is about the power supply for the heated bed. What kind of power supply will I need to supply the necessary power for this bed? Will i need something that can get 1600w? I assume that's what we connect the power supply to the relay and back to the board? Then do we need a separate power supply for the duet board and motors themselves? Still trying to figure this out. Sorry for my ignorance. Thanks!

@msquared

Thank you so much for the quick reply guys. It is clear I need to use a relay and that I don't want to be a cheap about it! @MSquared what premium relay would you recommend in this situation?

I would like the option of leaving my printer monitored without worrying about it failing and leaving the heat bed on. A good relay will be a big part of this it seems. I also see in the docs that you could install a thermal cutout to disconnect the heater at a certain temp. Do you recommend this too? Or is this unnecessary with a good relay?

This is my first project with the Duet Wifi so I am very new here. I'm looking to use the Duet wifi with this KEENOVO 500mm x 500mm 1600w 120v silicone heated bed.

What kind of power supply would be needed to make this work and how could that be wired to the Duet wifi? From the setup wiki, it is not apparent how you would supply a heated bed at this wattage. Also, I have not picked out the stepper motors or anything so I'm pretty flexible on that.

I appreciate the advice in advance!
