It is usually best to mount the motor in a way so it is spinning clockwise to avoid confusion.

Additional Information:
ok, but lets say the motors turn clockwise. if you mount it to ether side of the y axis it will pull to that side so what are the correct positions of the stepper motors. is it the left side or the right side of the y axis and also is it the front or back of the x axis?

Any of the following power supplies will be fine for powering the Mach3 USB controller:

however, the limit switches do not need high current, so the following power supply is sufficient for the task of connecting limit switches:

What power supply do you recommend for the spindle and limit switches if I buy the USB Mach3 breakout board?

Have you tried a different input pin?

Customer response:
I've tried all pins: 10, 11, 12, and 13. I get the same non-response in each case.

There may be a problem with the board. If you are using our parallel breakout board, we can ship you a replacement (call us), otherwise, you will need to determine the problem with the vendor of the breakout board you are using.

Additional Information:
I have tried 3 different breakout boards from 3 different providers and they all do the same thing My limit switches are microswitches wired NC with each axis wired to the BO Board. I have checked each circuit and all is OK to the BO board. each circuit has continuity at the board and when any switch is pressed the circuit breaks. Mach 3 does not recognise that the switches are even there. They are configured as active low Do you have a suggestion.

I'm having trouble getting Mach3 to recognize my limit switches. I've eliminated everything back to the breakout board. I can directly connect Input 10 to GND on the breakout board while Mach3 is in autorecognize mode and Mach3 doesn't acknowledge anything.

You will need a USB cable to connect the computer and the Mach3 USB. The 64-bit operating system must be Windows and you will need the Mach3 CNC control software installed on the operating system.

You will need to install the USB driver called RNRMotion.dll. You can find the driver here: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

Move the file to your Mach3 Plugins folder Example: "C:/Users/ProgramFiles/Mach3/Plugins"

Mach3 will prompt you to select a driver and this is where you can select the "RnRMotionController" and check "Don't ask me again". This will allow your board to communicate with Mach3.

You will also need the xml file found on this page: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

On that page, you will need to download the XML Mach3 Config File by right clicking on the link and selecting "save as". Save the Mach3Mill.xml file in your Mach3 root folder.

That file is the main configuration file for the Mach3 board. It has all of the typical settings that the Mach3 board needs.

It's generally acceptable to use one pin for all of your limit switches wired Normally Closed (NC), and another separate pin for a Z probe that is Normally Open (NO). LinuxCNC is quite flexible and allows for mixed configurations of NC and NO switches.

Just ensure you configure LinuxCNC correctly to recognize each pin's logic (Active low or active high). And perhaps run a few tests before running the machine.

[59] is it ok to use one pin for all of the limit switches wired NC and another pin for a z probe that is NO, or do all input pins need to be the same (NC or NO)? I would like to use LinuxCNC but will use Mach3 if necessary. a thanks!

If the Shark HD520 has separate drivers for each stepper motor, you will only need to change the controller that connects the computer to the drivers. If the Shark HD520 has the controller and driver all on one board, then you will need to get a controller and one driver for each stepper motor. You can determine if your electronics have independent drivers by opening the electronics enclosure and checking for three boxes each having wires that connect to a stepper motor (or stepper motor connector.

Hi. The relay that we sell here:
https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

Has the same relay as the parallel breakout board:
https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay

And contains three terminals: "S", "P" and "P". The "P" is always connected and will be the connection between the "S" or the "O" depending on if you need the connection to be Normally Closed (NC) or Normally Open (NO).

- Use the "O" if you need the connection from "P" and "O" to be Normally Open, meaning that the circuit will close (be connected) if the relay engages.

- Use the "S" if you need the connection from "P" and "S" to be Normally Closed, meaning that the circuit will open (be disconnected) if the relay engages.

You can actually set a current limit in in the VFD using the programming process and the specifications in the manual that came with your VFD. You can expect the spindle at 220 Volts AC to draw (using the standard formula):

For Volts, I will use 230 as the range is generally 220 to 240.

Watts = Current * Volts

Can also be written as:

Current = Watts / Volts

Current = 2.2kW (2200 watts) / 230 volts

Current = 9.6 amps

I have the 2.2 kW spindle and VFD for 110v, just wondering what amperage this draws, as my electricain buddy is telling me I need to put in a 20 amp breaker for this. I cant seem to find any amerpage draw on the INPUT label

The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.

The motor that is attached to the 4th axis is wired as follows:

The motor should have red, green yellow and blue wires coming form the motor. The red and green are paired as one coil and the yellow and blue is paired as the other coil. You can wire the motor to a 3.0 amp driver with red to A+, green to A-, Yellow to B+ and Blue to B-
