@Phaedrux okay I found the problem the gateway number was changed and I set it with m554

@jay_s_uk I am using one head which means one extruder at a time, but I couldn't use e0 motor with e1 heater and I just unplugged the e0 motor pin and put it to the e1 motor pin. and changed the d0 to d1. does it work if I use e0 motor pin, e1 thermistor and e1 heater?

I am using the DWC dashboard homing buttons.

@jay_s_uk Okay I changed the D0 to D1 and pluged the servo motor pin from e0 to e1 and its working no thank you for the help!!

but I still have issues with homing can you answer that please

@jay_s_uk when put P1 the name was showing up as Duet board, as you can see at the end of the heater part,thats why I used p2.

there was a continuity problem I change the cable and it solved.

For the extruder selection since I am using just one tool at a time I didn't change the extruder, should I still change it?
I try to load filament but it didn't work, does e0 driver work with second heater?
I tried to uncommenting
;M569 P5 S1 ; physical drive 5 goes forwards (E1 motor)
from the drives part
and I changed the D value to D1 in tool part
it didn't work.

lastly I changed the P5 to P7 since the P5 is used in drive 4, but there is an error now and it says drive 4 error: a and b phases may not be connected.

@jay_s_uk Also I want to ask another thing too, sometimes while I am homing the device it goes to the wrong way, even I didn't change anything on the config or I changed something unrelated to that(like heaters) it happens. what can it be the reason and can I fix it permanently?

@jay_s_uk hi thank you for the advise, I add to the config and i can see the heater 2 rightnow. but it shows -273C. is there a problem with my config or what should i do?

hey,

I was using E0 with one of my printer heads but I want to add the other pin to my config to use the pin with another cable and another head. I checked the new cable in E0 it is working, I took out the cable from the e0 put it to the e1 and i left the e0 empty. I went to config tool add a new nozzle named e1temp and e1heat. created a config, I took the lines which are related with e1 and add them to my original config. but i cant see the new pin on dashboard, also i sent the m122 it says heater1 is on but says nothing about heater2 which is e1. how can i use both pins with different cables and heads. when i change the head ill leave the other cable on the pin but wont use it.

@Phaedrux okay I found the problem the gateway number was changed and I set it with m554

@siladeniz I noticed that in the files config.g and config.json don't have same content. Is it should be like that?

@Phaedrux no because I don't want to use new config I just want to take the second heater lines from there and add to my config. Also while I am trying to update the documents which I got from config tool, I deleted www, firmware and sys files in sd card. and add the config tool generated www,firmware and sys files. later as I said previously it didn't work and I turned back to old files. I think I might delete something wrong I'll share the files with you can you check please?

or there is another option I can delete all the files in the sd card, I'll copy my config and macros. and I will download the latest firmware version and put it to the sd card. Does it work? I don't know if the other files can be arranged by user or just copy paste from the downloads thats why I don't know if I arranged them in some way.
here is the files:
