I don’t have good knowledge about robotics. Now I bought Arduino Uno, CNCShield + A4988, and two Stepper Motors NEMA 17. Now I want to know

1. What is the firmware or code that I want to upload to my Arduino Uno?

2. What is the software I use to make designs (if that is https://sandify.org/ waht is the export type(.scara or .thr, or .gcode, or other)?

3. What is the suitable software to send a G-code file or any file to the robot?

4. What is the software or Python code to if want to convert one type to another type?

SCARA Sand Drawing Machine

Grbl works on that hardware, I believe. Sandify. Use the “SCARA Gcode” export format. That format outputs X and Y, but those represent angles for the shoulder and elbow joints. Your use case is exactly what it was written for. Once you have a machine you can move around, you can work out the details. Universal gcode sender should be a good first step with grbl. There are many options. No conversion is really possible. You can save the file from sandify and open it back up later. Or you can also…

I created a new public post.

1. Can you send me the correct GitHub link for Grbl that you mentioned?

2. And I want to know below export is correct for my function?

The link Tom sent seems fine. I am not as familiar with it as Tom. So I would trust him.

The documentation for the export is here. Those settings look fine.
