Hello again thanks for the answers while I was waiting for the answers I realized the problem was from the config then I see the replies I disconnected the 24v from out0. also changed the bed output from out0 to out2. everything is working well right now sorry for the messy wiring and bad "color blob" wiring diagram. it was my first project
Thanks to everyone.
@rushmere3d 
Here is a more clear version. how we fix that problem
@ertence also it says beds are off but it's
heating uncontrollably
@stephen6309 Hello again. I check the post you mentioned. but I'm a newbie to be honest haven't noticed any problem. SSR immediately opens when I plug in the power. I can see the temperature but cannot control the relay as i said earlier
Here is my config and bed wiring

@jens55 Thanks for your answer I connected one of the heaters for testing but it keeps heating, I cannot get the problem? why is it keep heating?
Hi
i am having some issues with the silicone heater connections with Duet 3 6CH
I have 2x 240V 2000W 500x500 Heaters ; Current : 8.3A , Resistance : 28.8
I am Using 1x 40A SSR My PSU is Meanwell LRS-350-24 do I Need a extra PSU? how can I run 2 beds through to one SSR and Single PSU is it possible? is there any diagram for that type of connection?
Best regards
Hello everyone. I was working on my custom printer was about to get a test print
but the problem is it prints somewhere outside the print area I chose the black area which is selected as print area the red area is the machine starts to print
the Z-axis probing is functional there is no problem with probing its working well. 
here is my cura settings
Here is my config file

@rjenkinsgb Hello Robert thanks for your answer unfortunately it didn't work for me. I unplug all the slots except the driver 0 and the driver 4 slots as I said these are the slots with problems the others are working at the moment I still control them
@phaedrux these is no problem in phase connection when I plug the cable to the another slot its working there is no problem with the cables
Hello everybody im new with the duet boards. the question is I'm getting a error message when I try to check the steppers I'm building the frame at the moments so I didn't connect anything but steppers I have the Nema 17 US-17HS4401 and When I try to see the problem from the yat I get this message

I get this messages from the d0 and d4 ports the others are working well at the moment. Here is my config file config.g
