It appears that the LCD that you have on the vacuum pressure controller is damaged. You will need to remove the LCD (desolder the LCD) that is on the controller and resolder a new one.

Here is a link to the LCD used for that vacuum pressure controller:

I have a vacuum regulator pump controller that I purchased from you previously. The LCD display is now missing the bottom line of text. Have you run into this issue before? Can I just swap out the LCD displays or is a fix going to be more involved?

To install the USB breakout board, there will be no driver to install nor any pop-up will be viewed in your windows task-bar, except only to notify that a USB device has been connected.

If you have planet-cnc installed it should automatically ask for a license number, which if you don't have you will continue without entering any numbers. Please read carefully since there is a pop-up that can erase the entire firmware on your board, and you will basically have a dead board.

Please email customerservice@buildyourcnc.com for further assitance.

Additional Information:
For Windows 8.1 you need to follow special driver installation steps. Download Planet-cnc software MANUAL and scroll down to that paragraph (without it you will not be able to install and use your board).

Recommend first test to check a non-working axis, is to connect the current working axis(ex X-axis) to either the y/z axis to test the actual board and wiring in other axis setup. If tests failed and working (x-axis setup) does not working in the new axis location, go the Planet-CNC/File/Settings/Axes and check if your current non-working axis setup requires a inverted pulse. Check box and test again.
Next test if first fails, is to check continuity in your wires. A simple multimeter(ohm's) will work, just connect the positive and negative ends to one side of the same wire and if reading comes to 0.000, wire has continuity and if reads 0.L then there is a break in the wire and should be replaced.

The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

Additional Information:
I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

Additional Information:
Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

I have your Mach3 usb interface board and am interested in the relay board to turn plasma torch on/off. I have a different relay board that doesn't work, it needs 0/5v from output pin to trigger and the usb board doesn't put out 5 volts. Does this relay board need 5v on output or will work fine with this usb controller?

The mach3 control software will work with all major CAM software (CAMBAM, Aspire and Vectric, BobCAD/CAM, ArtCAM, Dolphin CAM, CAM software that integrate with SolidWorks and AutoDesk Inventor, and many more).

Adding more fans will require more power from the power supply. Each fan should have the amps that the fan draws. Add the total amps from the three fans and add one amp for the pump and you will have the total power requirement. The 12V 2amp power supply that accompanies the spindle cooling kit will probably be insufficient for the additional two fans.

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 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.

The USB controller will only work with the Planet-CNC software. This software is well made and will provide great functionality. The planet-cnc software delivers instructions to the microcontroller on the board and the microcontroller will send out the pulse trains needed to move the machine correctly.

There are two main alternatives if you want to use the mach3 software:
First, get a parallel port card and add it to your computer and get a parallel breakout board. If you have a laptop/notebook computer, this will not be possible.
Second, if you have a laptop, or really want to use the USB as the main interface for controlling the machine, you will need to get the smoothstepper board which works with mach3. The price combination is much higher than the USB controller with planet-cnc, but will work with Mach3.

The planet cnc controller can be prone to electrical interference and has been known to cause such problems. In the first instance try to use a quality double sheilded USB cable, hopefully this will fix your problem. Alternatively you may need to sheild your limit switch, estop and or motor cabling. My pick is that a quality USB cable will fix it though, worked for me.

The DRV8825 driver IC by TI (Texas Instruments) has two main connections called STEP and DIR. These are the two main connections that you need to use to connect to the Pokeys57CNC controller. You also need to connect the positive digital voltage pin (5V) from the Pokeys57CNC controller's motor connector to both the reset and sleep pins. The GND pin from the Pokeys57CNC motor connector is connected to the GND pin of the DRV8825 driver. The enable pin of the DRV88525 can remain unconnected.

There is a trimmer potentiometer on the DRV8825 that can increase or decrease the amperage setting for the motor. Depending on the DRV8825 board you purchased, there may be two pads to determine the amp setting while turning the trimmer (in the voltage setting on your multimeter).

The A1 and A2 is connected to one of the motor's coils and B1 and B2 is connected to the other motor's coil. There is a pin on the DRV8825 called VMOT that you will connect to the power supply (max 45VDC) and the GND pin next to the VMOT is the V- for the same power supply.

I hope this helps. If not, please add additional information on this thread.

Additional Information:
I followed (to the best of my ability) the instructions provided to my original question, but I did not receive successful results. When I followed the instructions and connected the ground pin from the Pokeys57CNC motor connector to the DRV8825 / A4988 expansion board, it stops the communication between the Pokeys57CNC board & the motors 1-3 that I had working previously. The DRV8825 / A4988 expansion board will be the fourth driver I am connecting to the Pokeys57CNC. The previous three drivers are PoStep-60's if that helps understand the issue.

Prior to hooking up the ground pin (I used pin 10 from the Pokeys57CNC motor connector) to the DRV8825 / A4988 expansion boards ground pin, I was able to see the power being applied via the red LED being illuminated on the DRV8825 board; after this new configuration the light is not turning on.

With the new recommended setup, I used a heat shrink solder piece to add the shunt for the connection to the sleep pin. The connection to the sleep pin is where I believe my issues are stemming from. I must be connecting it to the incorrect pin (within the 9 pin layout on the DRV8825 / A4988 expansion board). Do you have any reference to the 9 pin pinout on the A4988 expansion board? I double checked the pinout provided on the Texas Instruments page, but it only gives clarity to the pinouts on the DRV8825 board itself. After reviewing their documentation, I tried connecting the 5v (pin 9 from the Pokeys57CNC motor connection that's split to connect with the reset pin on the DRV8825 / A4988) wire directly to the terminal on the DRV8825 board and that didn't work either.

Any help or clarification you can provide would be greatly appreciated!
