Thanks for your reply.

I don't know, it's for a client. But we have already managed to go up to 500 ° c with 40 watts, on a marlin motherboard.

Hello,

On a Duet2 powered by 24V (600W), with 40 W E3D heaters, PT100 and PT100 daughterboard.

I can't reach 500°C, at 370°C the temperature stagnates.

And if i run autotune with M303 H1 S500, it failed with an error "Auto tune cancelled because target temperature was not reached"

I think i have enough power, could you help me please ?
