If your Z axis is moving in the opposite direction, go into Mach3, click on config, ports & pins, then click on the motor outputs tab. You will see the axes labeled on the left and the parameters labeled on the top of this dialog box. Toggle the dir low active for the z-axis.

Additional Information:
What if I'm having the same issue on a different axis?

Additional Information:
You can follow the same procedure as with the z-axis. When you get to the motors outputs tab, toggle the dir low active checkbox for the axis that you would like to change.

If you are using another control program, let me know and I will add the recommended action here.

My Z-axis seems to be reversed on a fully assembled machine... I've tried reversing it in the config settings on Mach 3, but to no avail. What do I need to do? IS this a wiring issue that was not done correctly at the factory?

To setup mach3 for the parallel breakout board, view the last three videos on this page:
https://buildyourcnc.com/CNCElectronicsandWiring.aspx#prettyPhoto

The parallel breakout board contains a usb connector, but is only used for power. The USB interface board (sold here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout) does not use Mach3, rather it uses the planet-cnc software.

bluechic v4.2 - mach3 setup video does not play on the metacafe site... since I'm new to this I am lost on how to configure mach3 to the usb breakout board. Please advise, thanks!

I have not come across this problem, but there may be USB, or firmware issues that you are experiencing. I would recommend going on the polabs website and using their support center (https://support.poscope.com/)and posing that question to them. Also, have you tried the ethernet port as an alternative to see if that helps?

Here is the response from an LLM:

Check USB Cable and Port: Start with the basics. Sometimes this error is due to a poor USB connection. Ensure you're using a high-quality, shielded USB cable and that it's plugged into a USB port directly on your computer, not through a hub. If possible, try a different USB port or a different cable to rule out any issues there.

Update Firmware and Software: Ensure that both your PoKeys57CNC firmware and the Mach4 software are up to date. Firmware updates for your PoKeys board might include optimizations or fixes that address connectivity issues.

USB Polling Rate: This error can also arise from the USB polling rate setting in the PoKeys configuration software. It might be set too high for your system's ability to handle it. Try lowering the polling rate and see if that resolves the error.

Computer Performance: Check your computer’s performance. If it’s running several heavy applications simultaneously, it might not be able to process signals from the PoKeys board fast enough. Try closing unnecessary applications or consider using a dedicated machine if your current setup is too taxed.

Mach 4 and PoKeys Plugin Configuration: Dive into the Mach 4 plugin configuration for PoKeys. Ensure that all settings are correctly configured as per the manual. Incorrect settings might lead to communication bottlenecks.

Connection Quality and Interference: Consider any potential interference sources near your CNC setup or computer. Electromagnetic interference from large motors, other electronics, or long cable runs can affect communication quality. Try rearranging your setup to minimize interference.

Consult Documentation and Support: If the issue persists, consult the detailed documentation provided by PoKeys or reach out to their customer support. They can offer more specific advice based on the latest product updates or known issues.

Drivers will have terminals with labels that represent a pulse, clock or step, and for direction. Look at the following to determine which terminal is used for what purpose.

Step- = CP- = P-
Step+ = CP+ = P+
Dir - = CW- = D-
Dir+ = CW+ = D+

Are you able to install a newer version of Mach3? If you are worried that your configuration will be lost, you can save the configuration by copying all of the XML files from the Mach folder. The XML files contain all of the settings that you applied in Mach3. Just in case the XML files are not compatible with the new version, make sure not to erase the current Mach3 that you have on the machine.

I am interested in the 3 axis combo USB option. I notice you endorse the Planet-CNC for use with this but will Mach3 interface well with the USB beak out Board?

The Mach3 USB controller does not provide 5V output signals. The Inputs, Outputs, and PWM Spindle Speed terminals are separated from the 5V side of the board. The output terminals use the 24V portion of the controller and you will need a 24V power supply to make these outputs work.

Please watch the video below to completely understand how the outputs of this controller work. Make sure that you are using the RNRmotion.dll plugin and that the port for each of the outputs is set to port 3.

Yes, you will need a sensor to determine the speed of the rotation. For instance, you can use a hall effect sensor and put a magnet on the shaft of rotation. By installing the hall effect sensor near the shaft that contains the magnet, you can use this to determine the RPM of the axis and reflect this value in Mach3 using an input in your controller and setting that input in the index line item of the Mach3 input signals dialog box.

Here is a great video that shows the circuit and process:

Click the link to add information to this solution:
You can set the Index input with Mach3 Turn and check that the Index is lit on the screen, but it is not reflected in the rotation speed. Is there any way?

If the outputs are not functioning as expected on the Mach3 USB controller, confirm that the port for the output is 3. This is a part of the configuration I did not show on the video I created on using the outputs for the RNRMotion controller.

Additional Information:
Thanks for your help. Under Ports & Pins>Output Signals I show Output#1 through Output#4 as Enabled. All have Port# set to 3. Pin Numbers for each Output# are same as Output# (Output#1 set to Pin Number 1, etc.).
Still no voltage showing on output 1 (of the board) when I input M3 in the Input section of the MDI tab. However if (in Spindle Setup tab) I set (in "Relay Control")M3 Output# to 3 and M4 Output# to 4 things work as expected. Is it possible to have the M3 signal show up on Output#1?
Thanks again.

Mach3 USB interface board initial setup. Following instructions in the video "Mach3 USB controller outputs". Arrow keys cause red LED to blink, but cannot duplicate 24V output with M3 (or M4) commands as shown in the video. Do I need to re-install Mach3?

Most likely, the driver is not receiving the high or low signal for the direction terminals. The way direction works for an axis is the controller will output a high signal (5V) for one direction and low signal (0V) for the opposite direction. If the signal is always at one signal, say 5V, whether it is commanded in one direction or the other, then the axis will only move in that direction.

To solve this problem, make sure that the wiring is secure at both ends (from the controller to the driver). Also, make sure the Dir+ and DIR- are both wired correctly (i.e. the Dir- is connected to the signal gnd on the controller and the ZD is connected to Dir+ on the driver.

You can use a multimeter to determine the voltage at the ZD terminal by:
- setting the multimeter to DC voltage (the V with a straight line, or dashed line above the V)
- place the black lead on the gnd terminal
- place the red lead on the ZD terminal
- press the page up button and check the voltage
- press the page down button and check the voltage.

You should see the voltage change from 0V to 5V or vice versa.

Hi I have just set up my machine using a mach 3 USB board I can only get the Z to go in one direction Y and X are Ok I have check wiring and looked at video over and over what have I missed??

In our experience, the backlash compensation is not an ideal mechanism to solve backlash issues. It is best to resolve the backlash issue mechanically regather than through software.

Boards that handle all instructions on its own chip (which is the case for this all other USB boards) take some control away from Mach3. Without Mach3 having granular control. With that said, we do not have experience with the backlash compensation with that particular board. Our experience with backlash compensation with other boards have resulted in very poor accuracy and undesirable geometrical moves.

Mach3 USB Interface Board, Backlash Compensation in Mach3 is not working. Does this board support the backlash function?

You will also need to check if the mach3 configuration and the wiring. Since you tested the connection from the motors to the drivers, the connection from the computer to the interface may still be the issue. It could also be the connection from the interface to the drivers, but we test all of these units going out, so I don't believe that would be the problem.

If you have a redfly that uses a parallel cable, you may need to check to make sure the parallel cable is functioning properly, and also, make sure that the interface is also powered using a usb cable.

If you have a usb interface (the terminals will be labeled XD, XP and so on), then there may be a wire not seated correctly in a terminal.
