The Mach3 USB controller will light a solid red light when the controller is properly connected to the computer, and mach3 is in the ready mode (reset pressed to engage the machine). When an arrow key is pressed to move an axis, the red LED will blink rapidly showing there is communication to the controller. If it does not blink rapidly, then check the motor output and confirm that the axes are enabled. Also, confirm you are in jog mode (located in the program run tab). You can also try using the built-in MPG by pressing the TAB key and clicking on the axis letters to move the axes.

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.

I HAVE FOLLOWED YOUR YOUTUBE VIDEO ON SETTING UP THE POKEYS 57CNC BOARD BUT WHEN OPEN MACH 4 GET A ERROR MESSAGE CONNECTION IS TO SLOW

Connecting drivers from a controller to the driver does not require relays. A controller typically has pins or terminals for Step and Direction. These terminals connect to the driver's Pulse and Direction terminals. For instance for the X axis: if you are connecting from the Mach3 USB controller, you would connect the XD (X axis Direction) terminal to the Driver's DIR+ terminal, and the XP (X axis Pulse) to theDriver's PUL+ terminal, and the GND from the controller to the PUL- and DIR- terminals.

You can adapt the Mach3 USB controller to control a laser, but I would not recommend it. A traditional laser controller that is designed to control a laser is far better since you can take advantage of more sophisticated features like sweep for engraving, and automatic adjustment of laser intensity for acceleration and deceleration. The Mach3 USB controller can move the axes and turn the laser on and off, but intensity control and engraving are not an option.

I have not tried connecting a 110V spindle to a 220V VFD; however, the parameters in a 220V VFD do allow changes to the values for the spindle motor. If you do plan on connecting the 110V spindle to a 220V VFD, damages can occur, so I would not recommend it.

With that said, here is the output of an LLM:
Using a 220-volt VFD (Variable Frequency Drive) to run a 110-volt spindle is technically possible, but it requires careful setup to avoid damaging the spindle. Here's what you need to consider:

Check the VFD Specifications: Ensure that the VFD can be set up to output the correct voltage for your spindle. Many VFDs are capable of outputting variable voltages and can be configured via their programming settings to match the voltage requirements of the spindle.

Adjust the Output Voltage: You'll need to configure the VFD to output 110 volts to match your spindle. This is crucial because supplying 220 volts to a 110-volt spindle would likely damage it permanently. Check the VFD's manual for instructions on how to adjust the output voltage settings.

Set the Current Correctly: Besides voltage, make sure the output current does not exceed what your spindle can handle. The VFD should be configured to supply the current at the rating appropriate for the spindle’s power and voltage requirements.

Consult the Manuals: Always refer to the manuals of both the spindle and the VFD. These documents can provide specific guidance on compatibility and settings.

Consider Professional Installation: If you are not familiar with electrical systems or if the manuals do not provide clear guidance, it may be wise to hire a professional. This helps ensure that the setup is done safely and correctly.

By taking these steps, you can safely use a 220-volt VFD with your 110-volt spindle, ensuring it operates efficiently without risk of damage. Just be meticulous with the settings and when in doubt, consult with or hire a professional.

It is possible to wire this controller so a spindle can be turned on and off, but spindle speed would not be possible and would need to be controlled from the control panel. It is not recommended to use a laser controller to control a spindle as a laser controller is specifically made for lasers to control speed and intensity. A traditional CNC controller is best to be mated with a system that uses a spindle as there are more sophisticated machining operations that take into consideration the features of a tool (end mill, drill, surfacing tool, etc.).

Additional Information:
I would recommend creating a system, similar to the greenBull, where there are two gantries on a single table where one gantry houses a spindle and the other gantry houses a laser. Each gantry can use a disparate controller, but be mapped/calibrated/aligned to the same surface.

That z-axis lead screw travels one inch with 5 turns.

Use the formula:

steps/inch

The steps will be the motor natural steps multiplied by the microstepping = (200 x microstepping)

The number of inches is the travel for one motor revolution = 1/5

Lets say the microstepping is 1/2, then the steps per revolution is 200 x 2 = 400

So: 400 / (1/5)" = 400 / .2" = 2000 steps per inch

The driver will have a dip switch that will show the microstepping setting.

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.

Make sure that the spindle motor output pin is not interfering with the signal. Go to config -> ports and pins -> motor outputs, at the bottom of the table, there will be a line for spindle. Make sure that spindle line item is disabled.

Additional Information:
I disabled the spindle port and I am still only able to activate port 3 and get 24v and even there when I enter m5 the voltage bounces all over the place. The other outputs read all over the place whether they have been designated as the spindle on the spindle settings tab

Wood dust can cause problems in a Variable Frequency Drive (VFD) like the Huanyang 2.2 kW 220V 400Hz unit. If wood dust gets inside the VFD, it can collect on important parts like the bakelite component on the heat sink. This can cause the part to get too hot because the dust traps the heat. When the bakelite component gets too hot, it can break. The dust can also block the airflow that helps to keep the VFD cool, making the heat problem worse. It's important to keep the VFD clean and away from wood dust to prevent these issues.

If you are not able to get any indication that an input is working, make sure to set the port of the input to 3 and set the pin of the input to the input number on the board. If you are using proximity switches, make sure you are using an NPN type and you are setting the active low toggle depending on if the switch is set for normally open or normally closed operation. You will also want to make sure the switch is wired correctly for either normally open (in parallel, like a ladder), or normally closed (in series) and make sure the correct leads are used on the switch.

I am assuming that you are referring to the Mach3 USB controller.

Your understanding seems mostly correct, but it's important to clarify a few points regarding the 3D touch probe and the Mach3 USB Interface Board. The probe has three wires: 24V+, 24V-, and a signal wire. Here's how it typically works:

24V+ and 24V- Wires: These are for powering the probe. Make sure they are connected to the appropriate power supply.

Signal Wire: This wire sends the signal to the board when the probe is activated. In your case, it seems to be connected to pin 4.

Active Low Setting: If the probe is Normally Open (NO), when activated (i.e., when it touches the surface), it will complete the circuit. If you're using "active low NOT ticked," this means the board will interpret an open circuit (no contact) as an active signal. When the probe touches a surface and closes the circuit, the signal will stop.

It's crucial to ensure that the probe's voltage specifications match what the Mach3 USB Interface Board can handle. Since the board's inputs might not be designed for a 24V signal, using a voltage divider or an appropriate interface circuit to step down the voltage to a safe level for the board might be necessary.

Hi. I have just purchared this board and will be using a 3d touch probe. The probe has 3 wires, 24v+, 24v- and a signal wire to the pin 4 (I think). The way I see it is that the probe is NO and the signal wire when activated will send a 24v+ signal to pin 4 (active low NOT ticked) activating the board. Would I be right in this understanding? Much apreciated.

You will need to look for the parameter that controls the run frequency. The frequency can be controlled bu the panel, external terminals, or the RS485 TX/RX terminals (UART protocol). You will want to change that parameter so it uses the panel. If you are referring to the maximum panel dial frequency is only allowing 200-300 rpm, then look for the parameters to control the frequency.

For 200 RPM:
Hz = 200/60 = 3.33 Hz

For 300 RPM:
Hz = 300/60 = 5 Hz

Conversion to RPM:
If you ever find yourself yearning to reverse-engineer the process, the formula is as follows:

RPM = Hz × 60

Look for values that match somewhere between 3 and 5 in your frequency parameters and replace them with 400 to give you 24,000 RPM max.

The Mach3 USB controller is specifically engineered to integrate seamlessly with Mach3's CNC control software. Easel, on the other hand, offers an all-in-one CAD/CAM solution along with machine control capabilities.

The output current for the Mach3 USB Interface Board is 50mA. These outputs are generally not designed to handle heavy loads like Spindle Governor Relays (SGRs).

If your SGR requires a hefty current. Attempting to directly switch it using just the Mach3 USB Interface Board would not be a good idea. In that case, using your existing C36 rev1.1 board as an intermediary is the way to go. That board can handle higher currents and will act as a buffer, ensuring that the Mach3 USB Interface Board doesn't get overwhelmed.

The Mach3 USB Interface Board is designed to handle an output current of 50mA. These outputs are generally not suitable for heavy loads like Spindle Governor Relays (SGRs)​​. Given that your SGR pulls 2.6 Amps, it exceeds the capacity of the Mach3 USB Interface Board's output. Therefore, directly switching the SGR using the Mach3 USB Interface Board is not advisable. Instead, using your existing C36 rev1.1 board as an intermediary would be the recommended approach. This board can handle higher currents and will act as a buffer, protecting the Mach3 USB Interface Board from being overwhelmed by the higher current demand of your SGR.

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.

This controller lacks the capability for backlash compensation.

In theory, utilizing a 5V reference in the 10V terminal of the Mach3 USB controller should yield functional results, although I haven't personally tested this configuration.

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.

You have the ability to designate the 4th axis, commonly known as the A-axis, for rotary indexing operations when using a Mach3 USB controller.

To achieve this in Mach3, you'll need to:

Open the Mach3 software.
Navigate to "Config" and then to "Ports and Pins."
Go to the "Motor Outputs" tab.
Enable the A-axis and assign the respective Step and Direction pins.
Save your settings and exit the "Ports and Pins" dialog.
To calibrate the A-axis, go to "Settings" and use the "Set Steps Per Unit" option.

For the NEMA 34 stepper motor with a maximum current of 6 amps, 18 AWG wire would technically be sufficient. According to the American Wire Gauge (AWG) standard, 18 AWG wire can handle up to around 10 amps of current in chassis wiring and around 16 amps in power transmission. If you are considering running a very long length of cable from the driver to the stepper motor, you may want to consider using 16 AWG.

As for the spindle, this wire gauge is well-suited. There are three phase shifts, each at 120 degrees and each conductor is carrying only 1/3 of the power. At 220v, 2200 watts / 220 V = 10 amps. 1/3 of 10 amps is 3.333 amps, so each conductor will be have a load of 3.33 amps.

Hi, What wire goes to input 3 for home limit and do I have to change anything in 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.

That depends on a few factors. In most cases, three 3.0 amp motors and drivers will not exceed 8.8 amps of available current. All of the motors would need to be at full torque to reach the 9 amps (3x3). This depends on the mechanical method you are using for each motor, and how you are using the machine. In most cases, only two motors are moving at a time (i.e. 3D carving where the X and Z are moving simultaneously and the y only moves to go to the next row). In traditional cutting profiles, only the x and y are moving simultaneously and the z-axis moves at the location it needs to start cutting the next layer.

With that said, it is ok to add an extra power supply if you feel you need more available current.

The outputs are independent of the PWM function of the controller. The PWM uses the ACM and AVI outputs from the controller to the VFD along with the 10V input from the VFD to the controller.

Yes, you can use 12VDC for the MAch3 USB controller at the 24V and DCM terminals. I have not tested using 12VDC in conjunction with the ACM and AVI terminals (PWM output) to control the spindle speed.
