Yes, you can have two drivers connected to a single axis. If you want the two drivers/motors to work as a single, more concerted pair, then I would suggest connecting the two drivers to a single step pulse and direction signal.

That is to say:
driver 1 and driver 2 have wires connecting from the CP terminals of the drivers to a single step terminal on the interface board (USB or parallel breakout board), and the CW terminals of the drivers connected to a single direction terminal on the interface board.

If the motors need to spin in the opposite directions, simply reverse one of the the motor A B coil connections (i.e. wires that would go to A+ and A- is connected to the B+ and B-, and the same with the B+ and B- to the A+ and A-). You can alternatively resolve this mechanically if desired.

Does your 3/4 comb support 2 driver board on a single axis contro board output interface?

In our 3-Axis electronics kit, the power supply's provided are capable of both 110V-220V. You have the capability to switch between both in case you might decide to run 220v in the near future or will relocate where 110v is being used.

Does the power supply in the "3 Axis Electronics Combo (Small Motors)" have a 220V input option?

Here is a list of the parts needed to get the electronics combo functioning (parallel or USB interface options):

- 22 or 24 gauge stranded hookup wire to connect all of the drivers to the USB or parallel interface (terminal to terminal connections),
- 18 gauge stranded hookup wire to connect the drivers to the power supply,
- a power cable (extension cord) to connect from the power outlet to the power supply,
- 4 conductor cable to connect the drivers to the stepper motors,
- a USB cable to connect from the computer to the USB interface (or for power to the parallel interface),
- for the parallel interface, a parallel cable is needed (male to male db-25),
- a computer (for parallel interface, the computer will need a parallel port and if the computer does not contain a parallel interface, the motherboard may have a header for it, or you can purchase a parallel adapter to plug into the motherboard, very inexpensive),
- cnc control software: for the USB interface, you will need planet-cnc software, for the parallel interface, you can use any industry standard cnc control software (the typical is Mach3 for Windows, or EMC2 or Linuxcnc for Linux (Linuxcnc.org).

5v power supply is not needed. The 5 volts signal level power is derived from the computer through USB on both types of interfaces.

If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

MY COMPUTER DOES NOT HAVE A PARALLEL PORT. HOW DO I INTERFACE WITH THE BREAKOUT BOARD?

We are currently getting it completed for us to post it under the 2.5A stepper driver page. However here is the correct wiring procedure.

First: Wire the 24V power supply to the 2.5A driver, by wiring +V on the power supply to 12-24V on the driver. Next wire the COM on the power supply to Ground(GND) on the 2.5A driver. GND on the driver will also go to the GND on the USB board, for specific axis. (additional 3-4 wires connected to ground will be needed for the other axes as well).

Second: Wire the USB board to the driver(one driver per axis on the USB board):
CP on the driver will go to CP on the desired axis on the USB board.
CW on the driver will go to CW on the desired axis on the USB board.
5V will go to the VCC pin on the keyboard jog pins on the USB board (check schematic here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/).
GND on the USB board to GND on the driver. (as specified in step 1).
EN is not used.

Personal Note:
I would recommend that you crimp the VCC pin to a wire which could be split for the other axes as well, each driver will need 5V.

Third: Wire the stepper motor to the driver, (using either the Nema 23 100-oz or the Nema 17 62-oz stepper motors, the wiring will be the same. For the Nema 23 the yellow and white is not connected.)
Black to A1
Green to A2
Red to B1
Blue to B2

Fourth: Repeat steps 1-3 for each driver/motor per axis.

Mention: Remember that GND on the driver will also go to the GND on the USB board for specific axis, and VCC pin on the USB board (keyboard jog) will go to 5V on all drivers for each axes as well, each driver will need 5V!

Attaching two motors in parallel is possible, but you will need another motor and driver for the opposite side. Each motor must have its own driver to work accordingly and fluently. The two can be wired together, to the same pins on your breakout board and set the dip switches on the driver to match the ones on your x-axis(ex). But remember to view the orientation of the motor and which way it spins, since it is on the opposite side it will have to be orientated correctly to move in sync with the other motor.

I just finished building my first CNC with the electronics I purchased from you and I am already thinking about improving it. I would like to build a 2 motor X axis solution. Is it possible to attach 2 parallel motors and drivers to the BlueBrew Breakout Board? If so, how?

Controlling a 3-axis or 4-axis motor configuration, you will need the following items drivers/motors/controller. Our electronics combo comes with the items mentioned and with power supply/miscellaneous items.
The only other item needed will be a computer (with controller software) to communicate and view controls of your motors.
Using the Parallel breakout board will use Mach 3 software, and USB will use Planet-CNC software.

Yes, with caveats. This kit includes a controller that will not be compatible, but if you use another type of controller that has web based control, you can use these electronics. Here is a list of web based control for CNC:

- Easel: The web-based software from Inventables can be accessed through Safari or other macOS-compatible web browsers.

- bCNC: A Python-based GRBL CNC command sender, although you may need to jump through some hoops to get it to run on macOS.

- Universal Gcode Sender: A Java-based software that should run on macOS if you have the Java Runtime Environment installed.

- CNCjs: Another web-based interface that you can run on macOS using Node.js.
