Why do you say it does not work?
2018-10-16 at 11:22 #20934yanaxParticipantwhen 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
2018-10-16 at 13:35 #20937DanKeymasteron 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.

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 degreesCheers Rob.
2018-10-17 at 00:35 #20941yanaxParticipantThank 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?2018-10-17 at 01:08 #20942yanaxParticipantHello 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 degreesThank you,
Yanax2018-10-22 at 08:54 #20966yanaxParticipantYou 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.
