Megateronic V2.0 use external stepper drive

I'm building a 3Dprinter and am collecting parts still mostly reading and learning.

A bunch of powerfull stepper motors, Nema 17 and 23 are waiting to be used but the A4988 won't drive these, 2 - 3 Amp will be needed.

Is there a good megatronics v2.0 design somewhere out there for use with external drives?

the reason i want to use external stepper drive becuz i dont know how to use 2 motor for Z axis
i used for Z axis 2 hiwin liner guide 15 with 2 blocks and hiwin ballscrew 1605 . so i need powerfull stepper to handle this

Thanks in advance.

Have you found a solution? I'm having the same problem. I did use E2 to move the other Z but it only moves in one direction

i changed from 2 nema 17 to one nema 23 with TB6600 external drive , the 2 motors in one axis have many disadvantage
