Hi i have couple of dynamixel ax-12a and arduino uno. The Goal is to make the servos read G-code from the arduino. I run it to couple of problems so i hope someone can help me and also I am very sorry if the same topic is repeating. Anyway I did manage to run the motors left right and change the speed on the rotation. So i follow an example to read data and send from the servo on my pc with IC 74LS241. I follow this video Maker Tutor. And i did everything like on the video but instead of getting some readings in my serial monitor i get squares and yes i try changing the baudrate and still noting.
So do i need some extra hardware to make the servos run with g-code like so shield or something else ?
Thank you for your time and excuse me if my english is bad.
Thank you again
I would really appreciate if some one can help me I really wanna start this project and i really need you help
Thanks again !!
Where in the dynamixel ax-12a manual did you read it could accept G-code?

I didn`t see anywhere that i can use dynamixel with g-code but i was thinking if i can use brbl software and interpreter so the dynamixel can understand and start spinning i would like to try that and if someone can help me i would be thankful.
If not should i ask my professor for some other idea or project with the dynamixel?
Thanks again for your time..

I think, perhaps, your project might take a year of concentrated effort.
Step 1 would be to write Arduino program to control and monitor the status of the motor.
Step 2 would be to get a copy of the GRBL source code, it is an interpreter of G-code designed to control stepper motors, and see if you can modify the GRBL code to use some of the logic you now have for the dynamixel.
In the meantime, make up several G-code instruction lines and mentally think of how you could use the dynamixel to accomplish the same thing.
What is the dynamixel connected to? A milling machine, a lathe, a 3-D printer? G-code is goal oriented, not just a motor movement language. It's goal is to move something an exact distance, or turn something on/off, and at the same time to ensure the movement will not exceed the limits of the machine.

Thanks for your response.
So I tried to accomplish the first step to learn about the positions of the motor but i think im gonna need a shield for the motor i tried like on the video that i post [dynamixel reading](https://www.youtube.com/watch?v=FNLvVoxKLc8) i did everything like on the video but i did not get my reading of the motor. So i only have made my motors go right or left and i can change the speed on the turning motor but i still dont know how to make it like to turn half way.
And the point on the project is not to making it finished product like with rails and milling my part its to make the motor read some what of the g-code.
I fully understand you that i need to make sure that this motors will do the exact spins in one way like 2cm by X axis or Y but for that i think i would need to have rails or something to move it on so it could make sense.
So now as you said if its gonna take year of time i don`t have that much time so maybe i should change my project?
Thanks again
