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.

If you are unable to install the parallel port driver during the Mach3 installation process, it is most likely that you are running a 64-Bit version of Windows. Install a 32-Bit version, and retry the Mach3 installation.

How do I wire two motors parallel

Wiring two motors in parallel is pretty easy.

Here are the steps:
- You need to have two stepper motors and two stepper motor drivers.
- Each stepper motor will be connected to its own stepper motor driver.
- Both stepper motor drivers are connected to the same CP and CW pins on the interface so the same signal is delivered to both drivers.

Yes, the best way to attach a relay to the output of the Mach3 USB board is to use an SSR (Solid State Relay) at the 24 Volt rating. This is the standard supply for this side of the Mach3 USB board.

Sure. If you had your own computer to start with and now need a replacement for it, consider our redSprout and redLeaf systems. You can find information about them here: https://buildyourcnc.com/AssembledElectronics.aspx If you started with one of our assembled systems, and only need to replace certain components, contact our sales department at sales@buildyourcnc.com for a quote.

If you are using a Parallel port card plugged into the motherboard in a PCI slot, or other compatible slot that interfaces directly to the microprocessor, you will need to make sure that the correct I/O address is entered into the configuration for your control software.

This I/O address is the first one in the range that Windows, or other operating system, will provide when accessing that information. In Windows, you would need to access this information in the device manager. Select the LPT port that is associated with the added parallel card. The port address will need to be in hex form, not decimal.

Other technical information that may help to understand the process:
The operating system will provide the address range, the first will be associated with pin 1, and the remaining addresses in the range will associate to the remaining pins (excluding the gnd pins) of the parallel port. This provides high and low signaling for each pin when a one is applied to the address. This is the reason the parallel port is called parallel, since each pin is independent and can output, or receive input simultaneously.

Here is how to connect your router to the parallel breakout board through the on-board relay. You will need a spare extension cord. You will need to remove a portion of the outer jacket of the extension cord to expose the white, black and green wires (white = neutral, black = live and green = ground), understanding that the neutral and live create the completed circuit.

See this image of a similar connection. The terminal has the same connections.
https://www.buildyourcnc.com/images/vacuum-pressure-controller-relay-terminals-700.JPG

Image of the relay terminal:
https://www.buildyourcnc.com/images/breakoutboardrelayNONC.PNG

The live/black wire would be cut and one end of the cut would be secured into the P terminal and the other cut end would be secured into the S terminal. The live and ground wire would be uncut and travel from the plug to the router.


Additional Information:
You can also connect other high powered devices to the breakout board using any of the output terminals. You will need to supply extra relays like the one shown here:
https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

Or you can find SSRs (Solid State Relays) that will accept 5v to drive the relay coil. Make sure the SSR will protect the 5V line from Back EMF as there is a coil in the relay. The one we sell contains a fly-back diode to protect the 5v terminal.
