Maestro Servo Wiring

  • I'm going use a BFPTouch (AKA: Servo & Optical Endstop: for my Z probe

    Can I just check the wiring before I do anything stupid.

    I then assume I just use P64 in my M280 (As pin 11 / SERVO = P64)

    Thanks in advance

    That looks OK to me. Your optical endstop may need 5V power instead of 3.3V. Take care not to short the 3.3V and 5V pins together on the Z probe connector.

  • @dc42 Thanks. I was going to go with the 5v Pin on the endstop, I'm going to use the 5 pin conector which should avoid shorting the 3.3 & 5V pins in this area.

  • with the maestro the wiring of the bfptouch is a lot easier

    you connect both red 5v lines to the 5v zprobe. both ground to z probe ground.
    optical sensor to z probe in like in your diagram
    motor servo to z _probe_mod

    M574 Z1 S2 ; Set endstops controlled by probe
    M558 P5 H5 F900 T4500 ; Set Z probe type to switch and the dive height + speeds
    G31 P1000 X22 Y0 Z0.90 ; Set Z probe trigger value, offset and trigger height (change these to your offset and trigger height)

    M280 P64 S40 ; Deploy probe CHECK YOUR ANGLE VALUE
    G4 P300 ; Wait 0.3 sec. (this will give enough time for the servo to extend)

    M280 P64 S0 ; Retract probe CHECK YOUR ANGLE VALUE

  • Thanks. It is working, with some fine-tuning it should be up and running over the weekend
