Hi, Today I'm configuring my heated bed, I'm receiving 2000° of temp, the wiring is ok, i tried to move the bed connector on extruder connector and it works.

My conf file is this:

; General preferences

G90 ; send absolute coordinates...

M83 ; ...but relative extruder moves

M550 P"RatRig CoreXY" ; set printer name

M667 S1 ; select CoreXY mode

; Network

M552 S1 ; enable network

M586 P0 S1 ; enable HTTP

M586 P1 S0 ; disable FTP

M586 P2 S0 ; disable Telnet

; Drives

M569 P0 S1 ; physical drive 0 goes forwards

M569 P1 S1 ; physical drive 1 goes forwards

M569 P2 S0 ; physical drive 2 goes forwards

M569 P3 S1 ; physical drive 3 goes forwards

M584 X0 Y1 Z2 E3 ; set drive mapping

M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation

M92 X80.00 Y80.00 Z400.00 E415.00 ; set steps per mm

M566 X600 Y600 Z60 E600 ; Maximum jerk in mm/min

M203 X12000 Y12000 Z1200 E2500 ; set maximum speeds (mm/min)

M201 X900 Y900 Z60 E1200 ; set accelerations (mm/s^2)

M906 X800 Y800 Z800 E800 I30 ; set motor currents (mA) and motor idle factor in per cent

M84 S30 ; Set idle timeout

; Axis Limits

M208 X0 Y0 Z0 S1 ; set axis minima

M208 X300 Y300 Z300 S0 ; set axis maxima

; Endstops

;M574 X1 Y1 Z1 S1 ; set active high and disabled endstops

M574 X1 Y1 S1 ; set active high and disabled endstops

M574 Z1 S2 ; set endstops controlled by probe

; Z-Probe

M307 H3 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch

M558 P9 H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

G31 P25 X-28 Y-37 Z1.88 ; set Z probe trigger value, offset and trigger height

M557 X15:215 Y15:195 S40 ; define mesh grid

; Heaters

;M140 H-1 ; disable heated bed

M305 P0 T100000 B3950 R4700 H0 L0 ; 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

; Hotend

M143 S240 ; max hotend temperature to 240C

M307 H1 A282.1, C183.5, D10.4 S0.6 ; PID heather

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

; Fans

M106 P0 S0 I0 F500 H-1 ; set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off

; Firmware Retraction & Pressure Advance -----------------

M207 S0.5 R-.1 F5400 T5400 ; Firmware Retraction : Positive S retracts, negative R unretracts (possitive R extra-extrudes)

; F retract speed, T unretract speed, Z zlift - Slicer must insert G10 & G11

M572 D0 S0.05 ; Pressure Advance, acts like 'coast' in Simplify 3D.

; Tools

M563 P0 D0 H1 F0 ; define tool 0

G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets

G10 P0 R0 S0 ; set initial tool 0 active and standby temperatures to 0C

; Custom settings are not defined

Thanks

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

I've changed it but same, I see 2000°

jay_s_uk

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

Dav

@SIam said in Keenovo 220V Configuration:

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?

SIam

@SIam said in Keenovo 220V Configuration:

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.

Dav

@SIam

It workssss! Thanks a lot!

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

SIam

yes it makes sense
