Question: [Mach3 USB Interface Board] Hi can I use a zeroing block with mock three interface board and do you have one I can purchase and directions on how to set up

Current Solution

Yes, you can use a conductive metal to serve as a zeroing block for the Z axis. All you need to do is connect the block (conductive metal) to one of the 4 inputs on the controller. The end mill must be connected to the DCM terminal (the GND of the 24V power supply) of the controller. In the inputs dialog box (config-ports and pins-inputs). Under the probe line, enter port 3 and the pin used for the block.

Can I purchase a computer off Amazon (I have a machine I want to use) and still use the USB interface to drive it with LinuxCNC?
You will need to build the table unit for your machine. There are instructions on how to do this at the bottom of the product page here, https://www.buildyourcnc.com/Item/cnc-machine-blackFoot-v4
There is no estimate on how much this will cost though, since there are too many variables involved to do this.

- PC with parallel port and USB port
- 20awg stranded wires for the motors - http://www.buildyourcnc.com/electronicscombo.aspx
- 18awg stranded wires for power supply to drivers
- 24awg stranded wires for breakout board to drivers
(location and spacing of components varies from one person to another, so we do not provide cables/wires)
- General purpose extension cord (cut the female end off) to provide power to power supply
- USB cable to power breakout board
- Parallel cable to communicate to breakout board
- Router
- (optional - instead of router) Spindle with power inverter http://www.buildyourcnc.com/SpindlesAndAccessories.aspx
- (if purchasing spindle with inverter) General purpose extension cord (240v) (cut the female end off) to provide power to power inverter
- End Mill(s) http://www.buildyourcnc.com/ProductsEndMills.aspx
- CAD, and/or CAD-CAM software (to produce geometry, machine operations, and g-code) http://www.buildyourcnc.com/CNCsoftware.aspx
- CNC control software (to read g-code and control machine) http://www.buildyourcnc.com/CNCsoftware.aspx

This answer is applicable to most of our machines with the exception of the greenLean and the blueChick since those machines are equipped with a table structure.

[575] I have a 64 bit Windows 11 laptop. Will this interface board work with this? If not is there an option you can suggest.
Yes, the Mach3 USB controller will work with the latest Windows version and in 64-bit mode. The 32-bit mode is only relevant for using the parallel port driver if you are using a parallel port breakout board. Since this controller is connected via a USB cable, the 64-bit state will work fine.

The motherboard on the computer I bought from you went out. What would you suggest. I have a laptop, could I use it and use a Mach3 USB interface board?
Yes, you can use a laptop if you have a controller that uses a USB, like the Mach3 USB card. If you don't have that, you can purchase that part here:
https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

If you have a controller board that connects to a 25 pin connector, modern laptops will not be able to connect to that port.

How old is your CNC computer system?

Additional Information:
The CNC computer system is 2013 (5 years). The built in video card went out. I will order the Mach3 USB card. Thank you.

[575] Can the 24VDC supply used for the interface board be the same supply used for stepper drivers, or do you need separate power supplies? If not, does GND and DCM need to be isolated?
I would recommend using a separate 24VDC power supply for the controller. The 24VDC that is connected to the controller is used for delicate input signals and output signals that control external devices. To keep interference and possible current and voltage fluctuations at a minimum due to the motor load, a separate power supply would be best.

HEY ! I HAVE PURCHASED A VFD WITH MATCHING SPINDLE 1.5KW AND CONTROL PROGRAM UCCNC. MY INTERFACE CARD IS DB25, THE QUESTION HOW DO CONNECT TO DB25 SO THAT CAN SPEED UCCNC? SINCERELY "CNC BEGINNERS"
Identify the Control Signals: First, determine which control signals from the DB25 interface card are used for spindle speed control. Typically, these are PWM (Pulse Width Modulation) signals or analog voltage signals.

VFD Configuration: Your VFD should be configured to accept the type of control signal your DB25 card provides. This involves setting parameters in the VFD that correspond to the type of input signal it will receive for speed control.

Wiring: Connect the appropriate output pins from the DB25 card to the input terminals on the VFD. This usually involves connecting the PWM or analog output to the corresponding input on the VFD. Make sure to consult the manuals for both your VFD and interface card for specific wiring details.

UCCNC Settings: Configure UCCNC to output the correct type of signal (PWM or analog) that matches your VFD's configuration. This is done through the software's spindle setup section.

Test and Adjust: Run some tests to ensure that the spindle speed is being correctly controlled by UCCNC. You might need to tweak settings in either the VFD or UCCNC for optimal performance.

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

Good evening, if I wanted to use your inductive proximity sensor's with your USB interface board what would I need besides the sensors I would be using 5 of the sensors. I have a 48V 12amp power supply. Thank you
I would suggest using the NPN proximity sensor for the Mach3 USB or the Pokeys57cnc. The proximity sensors have a top DC voltage limit of 30 volts, so it would be best to use the 24V power supply that is used to power the controller. Both controllers have a 24V power requirement, so that is convenient.

The blue wire of the proximity sensor is the GND wire and is connected to the 24V power supply's V- terminal. The brown wire is the positive wire and is connected to the V+ terminal of the 24V power supply. The black wire is the signal wire and is connected to the input terminal of the controller.

I am interested in using the Mach3 USB interface board. I was wondering if there was a way to run a torch height controller with this board for use with a plasma cutter, and if so do you know of any THCs that will work. Thank you.
Yes, you can connect a THC, Torch Height Controller, with the Mach3 USB controller. The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

I purchased a 3040 CNC router off eBay a year ago and would like to change the controls. The steppers are 185oz.in motors. My question do i need to purchase a interface board and break out boards?
When dealing with 3rd party machines, we have a universal setup that will fit almost any other machine, although please take in consideration the specifications in which your stepper motors and drivers are used and set to!
Now changing the controls, would be more or less changing the Breakout board/interface board to a different one that might use a different program to run your machine. Usually you will not need to change your interface board or breakout board, unless the 3rd party manufacture made it specifically to that set up.

On the pokeys57 board should I use the limit/home plug or just the block next to that plug form setting up home proximity sensors? I have them on the plug now and can not get them to work.
For setting up home proximity sensors on the PoKeys57 board, it's typically recommended to use the designated limit/home terminal or pin. This is because these ports are specifically designed for connecting limit switches or proximity sensors used for homing.

If you've already connected your sensors to the limit/home terminal and they're not functioning properly, here are a few troubleshooting steps you might want to consider:

Check Wiring and Connections: Ensure that the wiring to the sensors is correct and secure. Sometimes a loose connection can cause issues.

Sensor Configuration: Verify that the sensors are properly configured in the software you're using to interface with the PoKeys57 board. This could involve setting the correct sensor type (NPN or PNP), and ensuring the software is looking for the homing signal on the correct pins.

Test Sensors Individually: Disconnect other inputs and test each sensor individually to isolate the issue. This can help determine if the problem is with a specific sensor or the board itself.

Firmware and Software Updates: Ensure that your PoKeys57 board firmware is up to date, and that you're using the latest version of the control software.

[575] Although i have licensed mach, when i use that particular board it seems to run only 500 lines of code, how can i fix that? i
You should not have a problem with using this controller and having more than 500 lines of GCode. The 500-lines limitation is specific to licensing. Make sure that the Mach3 that you are using does not show "Demo" at the top of the screen. You can also confirm this in the help->about. If you are using a license that was purchased through this website, or from Machsupport.com, you should be fine.
