Questions about stepper motors

[Kimberly]

Hello,
I am new here and have almost no expertise in electronics etc., so I hope some experts can help me. For the past six months I have mainly been implementing Printing CNC (MPCNC) using Arduino Uno and Estlcam. However, I was able to do this because there were a lot of good instructions about it.

Now I am working on another similar project (electric respirator)...
I reached a certain point on the Arduino forum, but after that I could not go any further.
I am just not a good programmer and after 4 months of experimenting I have almost lost motivation.

My technical requirements for the project are:
Arduino Mega 2560 + RAMPS 1.4 + 4 DRV8255 plus four Nema 17 stepper motors (https://www.oyostepper.com/category-6-b0-Nema-17-Stepper-Motor.html) or TB6600 drivers for testing.
I have tried programming with Arduino, Labview and Blynk, but I don't know what else. But always only had small successes.
I managed to get the grbl-Mega-5X working and tried running four engines using G-code. It worked but at different speeds.

What is the minimum I need to achieve?
