M305 P0 T100000 B3950 R4700 H0 L0 ; set thermistor + ADC parameters for heater 0

Im not 100% sure but i think you don't need the H and L parameter for the bed

M305 P0 T100000 B3950 R4700 H0 L0 ; set thermistor + ADC parameters for heater 0

; Heaters
;M140 H-1 ; disable heated bed
M305 P0 T100000 B3950 R4700 ; set thermistor + ADC parameters for heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1
M143 H1 S280 ; set temperature limit for heater 1 to 280C

I've changed it but same, I see 2000°

What type of thermistor is it?

[Dav]

@jay_s_uk

Keenovo 300x300mm 220V 750W Silicone Heater Bed Pad w/ NTC 100K Thermistor

[SIam]

did you use a thermocouple or PT100 ? if not i think you don't need this M305 P0.6 X100 ; heater P1/H1 on channel 1

thermocouple

no nothing i only connected the bed withe the wiring scheme and a solid state relay

Genuine DELIXI SSR 40A480VAC Solid State Relay Input 3V~32VDC 40DA

so what i've to change in the code?

remove this :

M305 P0.6 X100 ; heater P1/H1 on channel 1

[jay_s_uk]

Check the thermistor input by connecting JUST a 100k resistor. The reading should then be 20 degrees.
This would confirm your code is correct and the issue lies with your wiring.

@SIam

It workssss! Thanks a lot!

Do you know if I need to do pid tuning for the bed?

[SIam]

yes it makes sense
