Dynamixel Shield fro arduino mkr1010 wifi. Not powering my AX 12-A servo

Use the following template to help create your post:

  1. State the model of servo you are using.
    I’m trying to get started with my new AX12-A motor, and the Dynamixel Shied for Arduino MKR.

I have the setup as the Robotis instructional youtube video regarding this shield (jumper, etc…), and I have the oficial Robotis psu reccommended for this shield.

The problem arises when I try to upload the example code sketch (simple/position mode)
Uploads correct, but the motor simply doesn’t move, doesn’t follow the commands of the script.

I tried the scan ID example sketch, and it detects correctly my only attached motors as ID 1.

I don’t know what to do do at this point.

Kind Regards

One thing firstly you should check is the code.

Upload the write_ax_mx.ino sketch by modifying Baudrate to 1M bps (AX series default bps) and see if the code working.

  // Set Port baudrate to 57600bps. This has to match with DYNAMIXEL baudrate.
  dxl.begin(1000000); # line 86

If Yogurt Man’s recommendation does not resolve your issue, posting the serial output from the ID scanning example sketch might help us figure out more about what is going on.
