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 an 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.

Re: Arduino Mega & A4988 Driver Module
I have ordered the parts to test adding a dual X&Y-Axis driver module that can be plugged into my Ramps 1.6 controller board.

Good luck. Let us know how it turns out. If it works, great. If it smokes, post pics. ![Very Happy :-D](./images/smilies/icon_e_biggrin.gif)

Re: Arduino Mega & A4988 Driver Module
The parts have arrived and will be test this on My MPCNC backup controller.
I will be posting my results.
The reason behind this is to get the E0, E1 back to allow me to 3D Print on this large MPCNC machine.
I have figured out how to install a hotbed and even level the bed on the MPCNC for 3D Printing only have to have extruder drivers.
