Dear respected sir, Hope you are in good health with success and happiness. I'm really happy for your awesome tutorials. But I'm facing a problem. I'm making a large size 3D printer where I'm using Nema 23 stepper motor which need 3A current.
That's means, I will use 4 Nema 23 Stepper motor.
In X axis 1 Nema 23
Y axis 1 Nema 23
Z axis 2 Nema 23

Those A4988 Stepper motor driver can provide maximum 2A current. Therefore, I am using TB6600 high power stepper driver. But I do not know the Pin-out to connect RUMPA board with TB6600 stepper driver.
Please sir, could you help me?
I will be grateful to you.

You might post this in the english speaking area of the RepRap forum to get more answers.
This should help you

It makes the four lines step, dir, enable and ground that are coming from the Rumba available.

And depending on which TB6600 drivers you use, you might have to tweak them a little bit.
I used the HY-DIV268N-5A and there are two tutorials how to improve them in terms of torque and stepping quality.
following links are in this topic:
Changing ICs => Stepping Quality
Changing resistors and bridging two pins => More Torque
