duet 2 wifi heaters e0 + e1

[engikeneer]

@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

[paolozampini1973]

@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

[engikeneer]

@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

[engikeneer]

@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%.

[paolozampini1973]

@droftarts config (10).g

[paolozampini1973]

@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

[droftarts]

@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-parameters

Snnn 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.

@paolozampini1973 also remove the M303 T0 S205 from your config and remove the M587 line from your config

[jay_s_uk]

@paolozampini1973 and you really don't want to be using 256 microstepping as it will overwhelm the MCU. Use x16 with interpolation instead.

[paolozampini1973]

@jay_s_uk because have dm860h

[paolozampini1973]

@jay_s_uk said in duet 2 wifi heaters e0 + e1:

M587

config (11).g
I did as you told me but anyway I'm going to set the temperature exceeds it by 20 degrees as you can see in the screenshot
