Hai,

I want to work back my Polar Graph, I see that there is new software
My Polar Graph enter the following connectors

Enable Motor1 = Pin 3
Step Motor1 = Pin 4
Motor1 dir = Pin 5

Enable motor2 = Pin 6
Step motor2 = Pin 7
Dir = motor2 Pin 8

Servo Pin 9

I use 2 x A4988 stepper drivers, to a design by Kritzler
I have also a other pcb print maked with follow connections

Step Motor1 = Pin 12
Motor1 dir = Pin 11

Step motor2 = Pin 10
Dir = motor2 Pin 9

Servo Pin A0

My question is, what Polar Graph controller can I use and what software should be placed in the Arduino Uno

Thanks for help

Kind regards
Sorry I'm almost 62 and sometimes forget what data

Ok, that's an unconventional setup, so I'm sure you understand that you've got to figure out some of this yourself.

Use polargraph_server_a1, but read the configuration notes at the top of polargraph_server_a1.ino.

Change the definition of what kind of stepper driver you're using:

//#define ADAFRUIT_MOTORSHIELD_V1
//#include <AFMotor.h>
...
#define SERIAL_STEPPER_DRIVERS

(https://github.com/euphy/polargraph_server_a1/blob/master/polargraph_server_a1.ino#L71)

Update the pin numbers in configuration.ino:

#define MOTOR_A_ENABLE_PIN 3
#define MOTOR_A_STEP_PIN 4
#define MOTOR_A_DIR_PIN 5
  
#define MOTOR_B_ENABLE_PIN 6
#define MOTOR_B_STEP_PIN 7
#define MOTOR_B_DIR_PIN 8

(https://github.com/euphy/polargraph_server_a1/blob/master/configuration.ino#L53-L60)

There is only one version of the controller, all of this stuff is bundled up in the latest release too: https://github.com/euphy/polargraphcontroller/releases/latest

Good luck 🙂
