    Hello Dan,
    I have print the file on thingiverse POLAR DRAWBOT by daGHIZmo.
    For the servo motor I saw that it was the towerpro SG90 on the photo .
    But it does not work. should I use another?
    The original one is too big for the ploter.
    Thank you,

    Why do you say it does not work?

    when I connect the cable to the servomotor, it is impossible to test the movement by the program of the pc.I am well connected.But the servomotor does not move.j’en is tested a second and it’s the same

    on our machines the servo wires for ground (black) and power (red/orange) are swapped. probably you have to do the same if you are using a RUMBA board.

    Hi yanax,

    This is the exact same setup I run, the daGHIZmo & that same SG90.

    As Dan said check your pinouts are correct.

    You can test the Pen Up / Down under Manual Driving in the Makeangelo software.

    ALso you may need to tweak the Pen up and Down angle in robot_polargraph.h

    Here is the angle’s that work for me.

    #define PEN_UP_ANGLE (180)
    #define PEN_DOWN_ANGLE (140) // Some steppers don’t like 0 degrees

    Cheers Rob.

    Thank you Dan,
    I use your Makelangelo 3.2.
    So I have a white red black connection.
    If I understand correctly, I have to connect the red of my new servomotor to the black of your connection.
    And the brown of the new servomotor on the red. Its good?
    And I still have the yellow that will go on the white?

    Hello Rob,
    Thank you for the answers.

    I have test the Pen Up / Down under Manual Driving in the Makeangelo software. But the sevo motor does not work.

    Is it possible Rob that you put me a picture of your connection red white black with yellow brown and red?
    I try your Angle.
    #define PEN_UP_ANGLE (180)
    #define PEN_DOWN_ANGLE (140) // Some steppers don’t like 0 degrees

    Thank you,
    Yanax

    You were right Dan.
    I reversed the connection of my brown wire with red and everything works.
    Which gives me black on red and red on brown and finally white on orange.

    Thank you so much.
