DUET WiFi E0 / E1 no workie - config?



  • RMAX V3
    DUET WiFi 2.02 firmware

    XYZ + endstops/homing all work perfectly

    PREFACE, I did fudge with the config, adjusted steps to 80, and deleted anything heated/thermistors, bed, and hot-end.
    Not extruding anything heated.

    The BIG DEALio (fail):
    The extruder stepper itself is connected to the E0 section, but it doesn't energise/show an LED, and the DUET WiFi interface has the Extruder controls grayed out and inaccessible:
    1_1558402261740_E0_STP_LED.jpg 0_1558402261740_Duet_GUI_01.jpg
    I have tried 2x other steppers and none of them seem to respond/show a connection to the Duet in either E0 or E1 positions.

    E0 and E1 steppers don't energize/connect
    wiring is correct/tried multiple steppers on both E0 and E1
    It must be my n00b-modified config.g
    Can you see what I'm missing? (config below)

    My JohnSL FSR board doesn't seem to respond at the DUET board either; it's properly sensing and the wiring is correct per the DUET2 instructions/wiring diagram...



  • for the extruder to work the hot end must be 160deg or you could use a M302 to allow for cold extrusion.



  • Yes, this machine will be doing cold extrusion exclusively.
    Where would I enter the M302 value?



  • Put it at the end of your configuration file.



  • XYZ steppers appear to be energised and have LEDs on.
    That, and I know they work since I can control them through the GUI.

    Does the LED for E0 / E1 only light up if extrusion is called for in gcode?

    How can I test the E0 / E1 steppers to know that they are working /wired correctly?
    Is there some gcode I can load to test them?

    LEDs are for the ends stops (and the two other E0/E1 leds are for the FETs)



  • How can I test the E0 / E1 steppers to know that they are working /wired correctly?

    How do I control them through the GUI/terminal?

    Any tests/ideas?



  • If you were to look up the M302 command you'd find you also need to specify which extruder to allow cold extruding for.

    Select a tool that has an associated extruder. Either set that tool to have no associated heaters in your M563 tool definition command, or enable cold extrusion. Then the extruder buttons in DWC won't be greyed out.



  • YES! Gracci dc42!

    M563 P0 D0 S"LDM_01" did the trick! now testable via GUI.
    Should there be a Duet LED (proximate to the connector like XYZs) showing that the E0 is energized?

    M302's not sure if they made any changes but added them as backup.

    NOW, on the getting the FSRs recognized by the Duet . . . (that's another forum post)

    M563 P0 D0 S"LDM_01" ; create a named tool using extruder drive 0

    M558 P5 X0 Y0 Z0 H15 F200 I1 ; FSR Settings
    G31 P500 X0 Y0 Z-0.3 ; Probe trigger value and offsets
    M270 I1 P1 S0.05 ; Enabled Probe doubletap w/ 0.05mm tolerance
    M557 R140 S30 ; default bed mapping
    M501 ; Load saved config values
    T0 ; Select Tool 0

    M302 ; Report current state
    M302 P0 ; Allow cold extrusion
    M375 ; Load height map

    Only if the heater or endstop is active.
