Keenovo 220V Configuration



  • 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°



  • What type of thermistor is it?



  • @jay_s_uk

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



  • 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



  • @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 said in Keenovo 220V Configuration:

    remove this :

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



  • 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?



  • yes it makes sense
