Best Cheap Control Board for Dual X, Dual E, and Dual Z And Config Help

[Roberts_Clif]

Both my 3D Printers run with a dual Z in parallel now for 3 years with no problems.
Do not like the ideal of twice the current though, if I designed the circuit would had wired them in series.

I have been thinking about my MPCNC it used X & E0 for X and Y & E1 for Y to drive stepper motors.
I want to change this and leave the E0 & E1 for Other purposes.

I have two ideals

1st - Can I wire two Stepper Motor modules to the same pins leaving the 4 pins connections to each Stepper motor separate.
This way I would have a separate Stepper motor module for each stepper motor and reversing JP3 connections would reverse the stepper direction.

Attached is a a4988 Driver module If connections were made to both drivers exactly the same on JP4.
Could I wire the two JP3 connections too two separate Stepper motors & even be able to reverse the connections to reverse the direction of turn, or will this overload the Arduino Mega 2560.

2nd - Wire the Stepper motors is series or parallel with a single stepper motor Driver module.

Not trying to steal your post, was hopping I could solve both with this simple post.
