Z endstop

  • Needs some help, I have read the documentation and i am having trouble making it work. Here is what I have in the config:
    M111 S0 ; Debug off
    M550 MyDuet ; Machine name (can be anything you like)
    M551 Preprap ; Machine password (currently not used)
    ;*** If you have more than one Duet on your network, they must all have different MAC addresses, so change the last digits
    M540 P0xBE:0xEF:0xDE:0xAD:0xFE:0xED ; MAC Address (hexadecimal)

    ;*** Wifi Networking
    M552 S1 ; Enable WiFi

    M555 P2 ; Set output to look like Marlin
    M575 P1 B57600 S1 ; Comms parameters for PanelDue
    ; Movement Section

    M569 P0 S0 ; X axis direction
    M569 P1 S0 ; Y axis direction
    M569 P2 S0 ; Z axis direction
    M569 P3 S1 ; Extruder Drive 0
    M569 P4 S1 ; Extruder Drive 1
    M574 X1 Y1 Z1 S0 ; set endstop configuration (X and Y endstop only, at low end, active high)
    M906 X800 Y800 Z800 E1000 ; Set motor currents (mA)
    M201 X800 Y800 Z15 E1000 ; Accelerations (mm/s^2)
    M203 X15000 Y15000 Z100 E3600 ; Maximum speeds (mm/min)
    M566 X600 Y600 Z30 E20 ; Minimum speeds mm/minute
    M208 X304 Y304 Z250 ; set axis maxima (adjust to suit your machine)
    M208 X0 Y0 Z0 S1 ; set axis minimum (adjust to make X=0 the edge of the bed)
    M92 X87.4890 Y87.4890 Z4000 ; Set axis steps/mm
    M92 E420:420
    ;M92 E420 ; Set extruder steps per mm (single nozzle)M92 E420:420 ; Set extruder steps/mm (dual nozzle)
    M350 X16 Y16 E16 I1 ; Set 16x microstepping with interpolation
    G21 ; Work in millimetres
    G90 ; Send absolute coordinates…
    M83 ; ...but relative extruder moves

    ; Probe Section
    ;P4 X0 Y0 Z1 H3 F200 T5000 ; smart IR Z probe, used for homming Z axis dive height 3mm, probe speed 200mm/min travel speed 5000mm/min
    ;G31 X11.0 Y0.5 Z1.2 P500 ; Set the probe height and threshhold (put your own values here)
    ;*** If you have a modulated IR probe with on-board microcontroller, change P2 to P1 in the following
    ;M558 P1
    ; Use a simple modulated Z probe (change to P1 for an intelligent Z probe)
    ;G31 Z0 P959 ; Set the probe height and threshold (put your own values here)

    ; Heater and thermistor section
    ;*** If you have a Duet board with 1K thermistor series resistors, change R4700 to R1000 to the following M305 commands
    M305 P0 R4700 H0 L0 ; Put your own H and/or L values here to set the bed thermistor ADC correction
    M305 P1 R4700 T100000 B4388 ; Put your own H and/or L values here to set the first nozzle thermistor ADC correction
    M305 P2 R4700 T100000 B4388 ; Put your own H and/or L values here to set the second nozzle thermistor ADC correction

    ; Tool definition section

    M563 P0 D0 H1 ; Define tool 0 to use extruder drive 0 and heater 1
    G10 P0 S0 R0 ; Set tool 0 operating and standby temperatures
    ;*** If you have a dual-nozzle build, remove or comment out the previous line, and un-comment the following 3 lines
    M563 P1 D1 H2 ; Define tool 1
    G10 P1 S0 R0 ; Set tool 1 operating and standby temperatures

    ; Bed probe section (not needed if you us a bed.g file
    ;*** Adjust the XY coordinates in the following M557 commands to suit your build and the position of the IR sensor
    M557 P0 X60 Y0 ; Four...
    M557 P1 X60 Y165 ; ...probe points...
    M557 P2 X222 Y165 ; ...for bed...
    M557 P3 X222 Y0 ; ...levelling
    ;M557 P4 X141 Y82.5 ; 5th probe point for levelling (un-comment this if you are using a dc42 differential IR probe)
    ;*** if you are using axis compensation, put the figures in the following command
    ;M556 S78 X0 Y0 Z0 ; Axis compensation here

    T0 ; select first hot end

    Here is Z homing:
    G1 Z4 F200
    G1 X45 Y70 F2000
    G1 Z-200 S1 F100

    Am I missing something?

  • G30 is for a probe., remove it. It should use the same method as x& y.

  • Perfect, working fine thanks
