@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

@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-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.

@jay_s_uk because have dm860h

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
