Hey!
I have been using this package for position control/velocity control and everything has been working fine.
My urdf is:

I checked in the model file (https://github.com/ROBOTIS-GIT/dynamixel_hardware_interface/blob/main/param/dxl_model/xc430_w150.model) and the Goal PWM address seems to be correct. Any Idea why this is failing?
Cheers!
