@engikeneer my duet wifi working 24v out heaters E0 + E1 MY TESTER OUT READER 12V heaters E0 + E1 12V POSSIBLE CONVESION VOLTAGE heaters E0 + E1 24V ?
Can you rephrase this? I have no idea what you're trying to ask.

@engikeneer The problem is that I have the heaters at 24 volts and not at 12 because I thought it was possible to use them at 24 volts through a jumper.
There is a jumper on the Duex to use 12v FANS even when the PSU is 24v. NOT heaters though.

-
@phaedrux so the heaters can work only and only at 12 volts there is no way to make them work at 24 volts
-
No that is not what I am saying.
If your power supply is 24v, your heaters will get 24v as well. No matter what.
For FANS on the Duex you have the OPTION for 12v or 24v with a selection jumper.
-
@phaedrux however, measuring 12 volts with the tester but the power supply is 24 volts
-
Where are you measuring 12v?
-
@phaedrux at the exit of the heaters E0 E1
-
Are you sure the power supply is 24v?
What do you measure at the output of the power supply?
-
@phaedrux YES 100%
-
-
@paolozampini1973 the output is PWM controlled, so may be that that you are measuring.
The outputs are switches on the -ve side, so measure between the +ve heater terminal and the -ve supply terminal -
@engikeneer
I made the measurement with the tester and I have 25 times Only problem is that it gives me this kind of error I would like to configure the heaters correctly if you can help me Thanks
-
@paolozampini1973 you need to tune your heaters so it can control them better:

@engikeneer that's what i'm trying to do but i can't figure out how having 24 volt 70 watt heaters
-
@paolozampini1973 so what happens if you send:
M303 T0 S205
Through the console. That should start tuning tool T0, up to 205C.
Once it completes, you'll need to send M500 to store the results in config-override.g, then make sure you have a M501 at the end of your config.g file to load it when you reboot
I would say that 70W is a very powerful heater for a 'normal' 3d printer, unless uou have a very large heater block (like the E3D supervolcano).
-
@paolozampini1973 the output voltage of the heaters is whatever the input voltage is.
-
@engikeneer I'm sorry please I can't figure out how to set the heater can you help me please Thank you
-
@paolozampini1973 can you post your config.g? It’s possible you have set the PWM duty cycle to 50%.

@droftarts config (10).g Sorry if I make some mess but I signed up since yesterday and I'm understanding How the forum works I hope nobody gets angry
-
@paolozampini1973 you have set the S parameter in M307 for each heater to 0.1, 0.5 and 2.0.
See https://docs.duet3d.com/User_manual/Reference/Gcodes#m307-set-or-report-heating-process-parametersSnnn maximum PWM to be used used with this heater on a scale of 0 to 1. Default 1.0.
Set them all to 1, then tune with M303.
