DUet Wifi / Rostock Max V3 Endstop issues



  • I am in the process of upgrading my Max V3 from the rambo to The DuetWiFi.
    I have followed Mhackneys excellent write up on it at http://www.sublimelayers.com/2016/12/co … v3-to.html

    My issue is the endtsops don't seem to be working right.

    The LEDs are lit beside the XYZ motor harnesses, and when activated by hand they turn off.
    The SETTINGS/ MACHINE CONTROL panel shows them as being trigger as they are hi, but when Home all is issued the carriages move up to the end stops, typically x triggers, Y triggers and then it keeps going up, grinding the motors until hitting the E stop Button. the odd time it is the Y that isn't triggering.

    The HomeDelta File is

    ; Homing file for SeeMeCNC Rostock MAX V3
    G91 ; use relative positioning
    ;******* Change F250 in the following line to F2500 when you are finished commissioning
    ;******* Change 320 in the following to a higher value if your Kossel has taller towers
    G1 S1 X550 Y550 Z550 F2500 ; move all carriages up 550mm, stopping at the endstops
    G1 S2 X-3 Y-3 Z-3 ; move all carriages down 3mm
    G1 S1 X6 Y6 Z6 F250 ; move carriages slowly up 6mm, stopping at the endstops
    G1 Z-5 F2000 ; down a few mm so that we can centre the head
    G90 ; back to absolute positioning
    G1 X0 Y0 F2000 ; centre the head and set a reasonable feed rate

    The Endstop setting is

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

    G21 ; Work in millimeters
    G90 ; Send absolute coordinates...
    M83 ; ...but relative extruder moves

    ; Axis and motor configuration
    M569 P0 S1 ; Drive 0 goes forwards
    M569 P1 S1 ; Drive 1 goes forwards
    M569 P2 S1 ; Drive 2 goes forwards
    M569 P3 S0 ; Drive 3 goes forwards
    M569 P4 S0 ; Drive 4 goes forwards
    M574 X2 Y2 Z2 S1 ; set endstop configuration (all endstops at high end, active high)
    ;*** The homed height is deliberately set too high in the following - you will adjust it during calibration
    M665 R144.158 L291.06 B120 H415 X0 Y0 Z0 ; set delta radius, diagonal rod length, printable radius and homed height
    M666 X0 Y0 Z0 ; put your endstop adjustments here, or let auto calibration find them
    M350 X16 Y16 E16 I1 ; Set 16x microstepping with interpolation
    M92 X80 Y80 Z80 ; Set axis steps/mm
    M906 X1000 Y1000 Z1000 E800 I60 ; Set motor currents (mA) and increase idle current to 60%
    M201 X1000 Y1000 Z1000 E1000 ; Accelerations (mm/s^2)
    M203 X20000 Y20000 Z20000 E3600 ; Maximum speeds (mm/min)
    M566 X1200 Y1200 Z1200 E1200 ; Maximum instant speed changes mm/minute

    Thoughts?

    Check that you don't have the motor or endstop connectors swapped, for example you may have the endstop at the top of the tower driven by the Y motor connected to the X or the Z endstop input instead of the X input. You can verify which motor is driving which carriage by commanding the motors to move individually as described in the wiki page on configuring firmware for delta printers.
