The fact that you cannot move the motors with the keyboard serves as a clue to a couple possibilities.

- The software may not be communicating with parallel port. (One possibility may be that your step pins are not low active, or vice versa depending on your drivers).
- You may not be in the correct tab of Mach3. Make sure you are in the Program Run tab.
- The jog on/off button on the program run screen may not be lit (invoked).

This address below shows the complete troubleshooting for this type of situation. It will show how to test each pin at the parallel port at the back of the computer and everything else associated with correctly wiring the electronics.

I bought Mach 4 and Mach 3 USB Motion card STB4100. The installation Manual you direct me to is for installing board with Mach3. Where can I find directions for the combination of products I bought? The axis motors are held stationary by the magnets but when I try to jog an axis from mach 4 program, no movement.

I am not using a parallell port. I am using a USB.

The relay is only used for devices like routers, spindles, coolant, mist, etc. The relay works like an automatic switch and will allow current to pass when the relay is engaged.

The relay doesn't have a A+ B - it has signal in god. 5v. / 0 S P. This has to go to my USB motion card wiring shows v+ goes to top of coil no number and comes out the bottom to #2 the relay I got from you is not that simple

On the Planet-CNC board, the Mist, Spindle and Coolant outputs will require a relay to switch on those devices. Test one of those terminals with a multi-meter (Mist, Coolant, or Spindle). Each of these terminals have a GND next to the terminal for the device.

Test the voltage across the GND to the terminal with the arrow that you want to test. Go to the software and click on the device you want to test (mist, coolant or spindle) and note the voltage. If no voltage is output then check under the board to where the terminals are soldered. Re-test the terminals across the solder joints rather than the terminal block wire inputs. If you get a voltage, then there is a problem with the terminal block. If you don't get a voltage, then the board is not functioning properly.

Additional Information:
I activated the output signal.. I did the tests indicated and I did not get voltage. I heated the welds of the three outputs and now works coolant but no mist or spindle, what should I do?

Additional Information:
There are probably cold joints on the board at the chip or the resistors on the traces for those terminals. You can send the board back to us and we will repair and test the board.

Additional Information:
If you want to troubleshoot this yourself, take a very close look at the traces from the terminal and follow them to the tiny resistors, then to the legs of the chip. If you see any bad or bridged solder joints, then those will need to be re-touched. It will take a somewhat experienced soldering individual to accomplish this task and will require flux to make sure the solder joints are fully joined.

Yes, the Mach3 USB board has two terminals that require 24V connection. Most VFDs have a 24V output that can be used to power this part of the Mach3 USB board.

The V+ and V- on the Mach3 USB is not absolutely necessary to operate the CNC machine/router. The V+ and V- of the Mach3 USB board powers the outputs, inputs, and spindle's speed and control.

Here is the Mach3 USB link for more information:
https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

The new YL600 VFD we have in stock may not have this 24V output. There is a 12V terminal, but I have not tested that terminal if it outputs 12V, or if it is a 12V input. If you are only conecting limit switches to the Mach3 USB and need to power that portion, 12V will be sufficient.

I will delve into these aspects in far more detail on video.

Thanks and Merry Christmas to you as well!

Hey Guys, I have a brand new redleaf and 5x. In the final stages of wiring and wondering a few things. Can I connect the Mach3 USB board V+ V- to my frequency inverter (type YL600-2s-2k20)? If so where? Will your upcoming (part 2)video deal with this as well as final connections for limit switches and stop button? Merry Christmas!

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.

[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.

Is this CNC related. If so, what controller are you using?

Additional Information:
I'm using the Mach 3/USB CNC interface board, with the Mach 3 software.

Additional Information:
Does the LED on the controller light up, or blink?

Additional Information:
I believe I've corrected the issue. I found that their are 2 spring like tabs on the female USB port. And take a sharp point like on a compass and gentle raise those tabs a bit. This tighten up the connection, and I never received an error from losing connection.

Yes, the RNRMotion.dll file must be used and put in the plugins folder under the Mach3 folder.

The XML file that I link on the Mach3 USB controller page is the file you should start with. This file will have the necessary configuration that links the Mach3 USB controller to the Mach3 control software. You can then make whatever changes you need to this configuration to tailor it to your machine.

Do you see a quick flashing red led on the board when you press the arrow keys?

[575] Do I have to use the motion driver and configuration file to use this card? The x,y,a shows that it's moving on display, but the motors aren't moving.

If you are wanting to use servos, I would highly recommend using closed loop steppers and drivers. You will get the best features of both the servo closed loop and the exact digital positioning of stepper motors.

For controllers: the pokeys57cnc will work with either Mach3 or Mach4

Hi there. I have an ex school Boxford HSRmi2 sat in my workshop, good condition and I'm assured it's all ok, but I want to rip everything out and go down the Mach 3/4 rabbit hole with servos. I need help at this point as I haven't done anything like this before and have no knowledge of controllers/motors etc. Could someone please point me in the right direction? Thanks.

Exhausting the blackTooth laser cutter is a very important consideration and should be taken seriously, especially if you are cutting materials that give off toxic fumes when the material is burned. You will want a 4 inch hose to connect from the blackTooth to a blower, and another 4 inch hose to connect from the blower to the outside. The blower should be sufficient to provide completely negative pressure within the laser enclosure so there will be no escape of gasses.

The connections at the machine, at the blower and at the location the hose exhausts outside should be thoroughly checked for leaks. Use a gasket, or silicone. Once complete, try cutting a non-toxic material that will give off an odor (wood, or non-toxic plastic) and try the system and determine if the smell is present.

The THC and the triggering of the plasma are actually two different functions of a controller. To trigger a plasma cutter, you can use one of the outputs of the Mach3 USB controller (out 1, 2, 3, or 4). That output can be connected to a relay that connects to the two wires that will trigger the plasma.

This video will show how this is done:

[575] How can I wire/ configure for a plasma cutter without THC? Plasma cutter has a cnc port, where when you short two of the pins, it activates the cutter. Just looking to see how to make that short when pressing f5 in Mach3.

To connect the stepper motor drivers to the Mach3 USB interface card, you will need to follow the wiring diagram here: https://www.buildyourcnc.com/Documents/Electric%20Wiring%20Diagram.pdf
which can be found here: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board along with all of the other manuals associated with that interface card.

Please note that the DC+ and DC- on that wiring diagram (power supply to thye stepper motor drivers) is not correct. The DC- is connected to GND on the drivers and the DC+ is connected to VCC on the drivers. Typically, the DC+ on the power supply is labeled V+ and the DC- is labeled either COM or V-.

If you are having any issues with the wiring, please let me know and I will elaborate. Thanks.

Yes, Mach3 (the software profram) will work with Windows 7, and windows 10 when coupled with the Mach3 USB interface. If you intend to use the parallel port driver, stick with Windows 7 in 32-bit mode.

Additional Information:
Rnrmotion.dll is a dynamic link library which is very similar in function to an executable program, or app. Since a dll is executable, malicious code can be embedded in that type of file, so windows will automatically flag all files of this type. You just need to make sure you are downloading from a trusted source. The emotion.dll file on our site is clean, but still run run windows defender against it to make sure.
