Adding mains 6amp 240v heated bed to Duet2 wifi

FuseDeep

Hi All,

Thanks for your ongoing help with my other bits and bobs, am in and out of the studio and fixing things as I go along (my M2 with new heated bed is printing amazing now, thanks to your help). I'll be sorting the z bounce on that soon...

Am also looking at putting a 240v 500x500 heated bed on son.im/fusedeep ;

...and wondered if my duet2 wifi board already has this capability or can do that or do i need one of the breakout boards?

@fusedeep, you would run that heat pad via an SCR. The SCR is activated with your Duet heat bed output.

@jens55 It's called an SSR (Solid state relay)

@fusedeep What you want is an SSR and my advice buy a quality heater and SSR, from the likes on Keenovo. I wouldn't trust an eBay product for this.

In addition to a quality SSR you also want a thermal fuse and start thinking about grounding everything more seriously. AC is no joke.

Dooooohhhhjh .... old fart moment .... sorry (in my defense, I knew exactly what I meant )

Thanks everyone, I have emailed keenovo and will see what they come back with.

Is there a wiki page showing how to use the duet to trigger a SSR and also control temperature?

Thanks Richard
