Hello.Maybe someone has connected such a controller. I
s it possible to use a stepper motor
It is possible. I am using one for some years now. Use the search function of the forum with “stepper”.
I can’t find a detailed description of how and what code to use, some write that you need a separate Arduino. I’m not very professional to understand. It would be good if someone would explain it in detail. I would be grateful
I can try to explain, but a closed loop stepper motor adds one (or more ) additional layer of completely to the hardware/ software tuning. If you are new to agopen and the Arduino+ world , I suggest to stay with the common DC motor setup. I really like my solution and it offers a lot of possibilityies, but it can still be called “experimental” , if you don’t want to thinker on it.
I have been using aog for more than 5 years, everything works perfectly. I can’t program, but I know how to upload arduino code. I wonder if you have adjusted the arduino code or are you using a separate arduino to control the tb6600. Thanks
maybe it would be possible to get a diagram
I am using this code (fork of MTZ8302): GitHub - hagre/AOG_Autosteer_ESP32: AgOpenGPS V4 autosteer code for ESP32

do you use with relays?
The relays are used as a safety feature do completely isolate the motor and avoid blocking of the steering. It was just planed for the prototype, but they are still in. The relays are not needed anymore, they make just trouble in rear cases, when the closed loop stepper driver is sensing a relay in transition. The resistors in the schematic are to close the sensing circuit of the driver.
Skip the relays!
Avoid the rabbit hole of normal stepper. Use Closed Loop Stepper with as much torque as possible, otherwise you are spending more money for not satisfactory tries.
Thanks
I have fully compatible setup with steering mechanism and ECU. It runs by UDP, uses stepper with encoder and loop control. It means it stops running if you pull hard the steering and lights the Red light on AOG and switches off the autosteering until you press the Enable button again (just like any other industrial auto guidance ).
