Endstops with external motors

  • Our Z axis is controlled by an external stepper (using the E2 pins), and is talking with the board, our next job is the endstop for this.
    We are connected via the expansion pins to E2_Stop and also GND (using the same principle as below which is working).
    Our X and Y uses the onboard drivers and the endstops are working correctly using only their own GND and STOP pins

    So I'm guessing that we need to change the commands, but to what?
    M574 X1 Y1 Z1 S0 ; Define active high microswitches
    M558 P1 X0 Y0 Z0 H5 F120 T9000 ; Set Z probe type to unmodulated, the axes for which it is used and the probe + travel speeds
    G31 P600 X0 Y0 Z2.5 ; Set Z probe trigger value, offset and trigger height
    M557 X15:2285 Y15:2085 S20 ; Define mesh grid

    Mapping the motors with M584 does not map the endstop connections, so you should still use the Z endstop connector even if your Z motor is connected to the E2 driver pins.

  • that is what we first tried, but with no luck, which is why we tried E2Stop

    have sorted it now in the homez file
