    • How to connect integrated servo motors

      Hello
      I want to make one arm SCARA drawing manipulator with large working area. So I decided to use Teknic Clearpath integrated servo motors.
      I try to fing answer at wiki how to connect them, but “Using external drivers” page are empty.
      Can you please explain how to connect Clearpath to Duet2wifi?
      Thank you!

    • RE: How to connect integrated servo motors

      I need not less than 5VDC and 8mA. So I need to order Expansion breakout board for Duet2, correct?

      Also can I make some changes at the interface layout? For example delete joggers? Or 3 different homing buttons?

    • RE: 4 motors on one axis homing

      @fcwilt
      Heavy X axis with Z axis mounted on it.
      taking into account the low cost of the steppers, and 6+3 driver on Duet3 + 3HC I decide to put 2 motors for 1 belt and thereby reduce the backlash and increase the torque. Which is especially important for high accelerations of a heavy head. And I plan to put a spindle in addition to the print head to be able to finish the surface after printing and drilling holes

      @o_lampe
      in this case endstop detection will be considered at a stall detection from the first of the two motors if they do not stall simultaneously? Or do both motors need stall detection to trigger the endstop?

    • RE: 4 motors on one axis homing

      @phaedrux any idea if sensorless homing should use both motors pulling one belt or just one of them?

    • RE: 4 motors on one axis homing

      I probably can place endstops for the Y axis. But for X and Z it will be almost impossible.
      For sensorless homing should I use both motors pulling one belt or just one of them?

    • 4 motors on one axis homing

      Hello
      I building a laser engraver with Duet3 + Duet 3 Expansion board 3HC
      I have 2 motors on X (both motors moves one X belt), 4 Motors on Y (two motors moves left Y belt, two motors moves right Y belt) and 2 on Z (8mm lead screw).
      Can I use sensorless homing in case of 2 motor moving same belt?
      what will the Homeall file look like in this case?
      Do I need to change motors mapping?

    • Connecting 3 wire fan Toolboard

      Hello
      I try to connect 3 wire FAN BLOWER 35X10MM 12VDC WIRE (Delta Electronics BFB03512HHA-AF00) to Out 1 of Toolboard.
      Fan start spinning at the power up and continues to spin at a constant speed regardless of the settings and commands M106 and M107.
      Wires connected: Black to GND, Red to +12V, Blue to out1

      ; Fans
      M950 F0 C"20.out1" Q1000 ; create fan 0 part cooling on pin 20.out1 and set its frequency
      M106 P0 S0 ; set fan 0 value. Thermostatic control is turned off
      M950 F1 C"20.out2" Q500 ; create fan 1 heatsink on pin 20.out2 and set its frequency
      M106 P1 S0 H1 T45 ; set fan 1 value. Thermostatic control is turned on 45C

      I tried several Q parameters. H-1 at M106 also didn't help.

      any ideas that I messed up?

      I add those 3 lines in my config file

      M280 P0 S60 ; BLtouch - toggle switch mode
      G4 P1000 ; wait 1 second
      M280 P0 S120 ; BLtouch toggle self-test

      , but BL-touch still does not perform self test at startup. M401 and M402 works
      There exactly I should put these lines? Just before ; Z-Probe ?
      Or at the top or bottom?
      And do I need any modifications to those codes since I use Toolboard with CAN address 20, not 121?
