The pulse stream is output directly from the onboard microcontroller on the Mach3 USB controller, so there is no need for a safety charge pump from the computer to the controller. Parallel port breakout boards were connected to the computer via GPIO pins (General Purpose Input/Output) and each pin dedicated to the step pulse would be output directly from those pins. In that case, a safety charge pump was needed.

The wire connection to this driver will depend on What you are connecting to the driver.
- For the motor connection to the driver, use the motor's datasheet for the connection schema. If the motor has 8 wires, apply the bipolar parallel connection schema.
- For the power supply to the driver, use a DC power supply that does not exceed the rated voltage displayed on the front of the driver. 48VDC or 36VDC is recommended for this driver.
- For the digital connections from the Mach3 USB controller to the driver, the PUL- and DIR- should connect to the gnd terminal on the controller. The XD (the X-axis is used in the example) should be connected to DIR+ and XP should be connected to PUL+ For the Pokeys57CNC, the step pin connects to PUL-, the DIR pin connects to the DIR- and the 5v connects to the DIR+ and PUL+.

Glycol can be problematic used in chillers unless the chiller is made specifically for glycol. Glycol can become more corrosive over time and cause damage to various parts of the chiller, including the pump. If you frequently change the fluid, you may be safe, but you will want to monitor the condition of the pump and other parts of the chiller. A concentration of 30% glycol and purified deionized water with a pH level between 7.0 and 8.2 will be a good mixture that may prevent corrosion over a period of 2 to 3 months.

There are a few ways to determine if a driver is not functioning properly. In all of the recommended actions below make sure to turn off all power and allow all energy to bleed before making any changes. This usually takes about 10 seconds, but you should allow at least 1 minute as different power supplies work differently.
- First, if the red LED is on, then the driver is in an error condition telling you that either the motor is connected incorrectly to the driver (one coil is connected across the A and B terminals of the driver), or the incorrect Amp setting is used. If you are certain the motor is connected correctly, i.e. one coil is connected to the A terminals and the other coil is connected to the B terminals, then try lowering the Amp setting and try again.
- If the axis is not working at all, there may be an issue with either the wiring from the controller to the driver, the controller could be bad, the driver could be bad, the motor could be bad, or the wiring between the motor and the driver is bad. If check if the driver is bad, you can move the signal wires coming from the controller that you know is working and wire them to the non-working driver. If the axis still doesn't work, then there is a problem with either the driver or the motor. At that point, disconnect the motor from that driver and connect a know working motor to that driver. If the motor turns, then you know the problem is the motor that was disconnected. If the motor does not turn, the problem is most likely the driver, but still could be the wiring from the controller to the driver, so you will want to confirm that connection.

[56] Hello, how to tell if a driver is bad?

The HY VFD has three main terminals for PWM control. These terminal inputs are:
- VI for the analog (PWM) voltage input (input at the VFD, output at the controller, i.e. the Mach3 USB controller),
- 10V output (this is an output from the VFD and an input at the controller) serves as the high voltage value for the width of the voltage,
- and ACM the ground from the controller (DCM at the controller)

In the parameters:
- PD002 should be set to 1 (one). PD002 is the source of operating frequency which is the RPM of the spindle in the Hz frequency units. 400Hz = 24000 RPM.
- PD003 specifies the frequency range for these terminals (10V, VI, and ACM) where 10V (voltage reference) is 400Hz and 0v is 0Hz, and VI adjusts the range from 0 and the voltage reverence (10V).
- PD070 selects the voltage range or current range (for use with the AI external VFD terminal as opposed to using the VI). You want to keep that parameter at the factory setting of 0 (zero) 0-10V.

To make an axis move in the opposite direction to what it is currently moving, you will need to toggle the ":direction:" active low setting for that axis. for instance, if when you press the page up button and your z-axis move down instead of up, then you need to make this change in the configuration.

To do this in Mach3:
- Click on the config option in the top menu
- Click on ports & pins
- Click on the motor outputs tab
- on the axis you wish to reverse, click on the "dir active low" to toggle the state of that parameter.

If the Z-Axis is moving down when you press the page up or page down (or by moving the z-axis by another means like with an MPG, Pendant, or the built-in MPG in Mach3), then the direction signal wire is not connected correctly. The direction signal wire works by moving in one direction with a low signal (like gnd) and moving in the other direction with a high signal (like 5v). If the signal stays at one of the two signals, it will only move in the direction of the current signal state. Recommended action is to determine if the DIR- and DIR+ signal wires are connected securely and make good contact at the driver and controller sides.

You can change the direction of a stepper motor's rotation by swapping the A and B coils where the stepper motor is connected to the stepper driver. This may not work with every stepper motor and driver combination.

To do this:
- Turn off all power to the stepper drivers. If this is not done, you will damage the stepper driver.
- Wait at least 1 minute for the power to dissipate from the drivers and power supply.
- Once power is off, remove the wires from the A+ and A- and insert these wires into the B+ and B- respectively. Then insert the wires that were in the B+ and B- into the A+ and A- respectively.

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.

Click the link to add information to this solution:
[51] Would the single 8.8A power supply be undersized for 3 6.0A Drivers? would you recommend getting another PS?

Yes, all you need to do is purchase an extra driver. If you are purchasing the 4th axis from us, you won't need to purchase a motor since the 4th axis already has a stepper motor in the assembly. If you have a 4th axis, make sure your 4th axis has a stepper motor, otherwise, you will need to purchase the appropriate motor.

This is a very broad question, but some possible reasons could be:

- The material you selected cannot absorb the laser energy. CO2 lasers cannot cut metals, for instance, unless very high-powered lasers are used and with the help of oxygen.

- The laser mirrors are not aligned properly and the laser energy is not, or fully exiting the aperture of the nozzle.

- The CO2 laser tube is not working, or the tube has passed the working number of hours.

- The CO2 laser tube power supply is not functioning properly. To test this, you will need a special multimeter probe. This multimeter probe would be able to probe high voltage on the high tension line: https://amzn.to/3SywRuK. Seek the assistance of an electrician that works with high voltage devices before trying to probe. The high-tension line is approximately 10,000 volts and is able to arc a good distance.

- The controller is not triggering the CO2 laser power supply.

Do you see the laser tube glowing when you are triggering the laser with the controller? Is there a test button on the laser tube power supply that you can use to test the laser?

If you already have a Mach3 license, you don't need to purchase another one. The license is connected to you rather than the computer. Mach4 is licensed to the computer, but you are able to have multiple computers for each license, and can be switched from one computer to another.

If you purchased the license from me, you can call (make sure to leave a voicemail), or email to get a re-issued license.

I will have to buy a new license for the Mach 3 so will need to get the interface board I have to talk to MAch 3. Can I get just the disc or is there a place I can download what I need?

Yes. You don't need to power the board with 24V. The controller will work with only a USB connection to the computer. However, the Input and output terminals (IN1-4 and OUT1-4) will not work without at least 12V on the DCM and 24V terminals.

The dip switches for the DM542 are as follows:

Switches 1, 2, and 3 relate to the amp setting for the motor connected to the driver. Take a look at the datasheet for the motor that you have. If you are connecting the 425 oz-in NEMA 24 motor, the Amp setting should be around 2.8, so the dip switch setting is 1-on, 2-on, and 3-off. If you are using a NEMA34 motor from buildyourcnc.com, set the amp rating to the highest at 1-off, 2-off, and 3-off.

Switch 4 is the setting for half or full current when the motor is at idle. You can set this to either full or half, unless you are using a rack and pinion and the axis is experiencing a load, like gravity. In that case, make sure switch 4 is on for full current.

Switches 5 to 8 relate to the number of micro steps for each step. A stepper motor with a 1.8-degree step will have 200 steps per rotation. If you wish to increase the number of steps per rotation, you can set these switches so that you can have more granularity. This will depend on the mechanical configuration of the axis you are setting. For instance, if you are using a lead screw that has a lead of 1/2" travel per turn, you will want to set the axis to at least 1/4, or 800 steps per rotation. If your mechanical configuration is rack and pinion, or roller chain, you may want a higher micro stepping to achieve greater than 1000/inch resolution on that axis. For instance, if the axis has a drive sprocket with a roller chain that has 14 teeth and the tooth pitch is 1/4", use a 1/16 microstepping setting or 3200 steps per rotation.

You want to look for the analog input terminals in the wiring diagram in the manual for your VFD. I believe the VFD you have, the XSY-AT1 has three terminals that will accept an analog voltage to adjust the speed. These terminals are:
COM or ACM - this is where the ACM from the controller will connect
VI/CI - The AVI will connect to this terminal which is the actual voltage level that will determine the speed from 0 to 10V.
10V - This connects to the 10V terminal of the controller which will provide 10V to the controller allowing the top voltage reference for the controller. This will provide a 0 to 10V range for the AVI or VI/CI terminals, and if 5V is available on the VFD, then the range will be 0 to 5V.

The parameter you need to change in the VFD is P10 which will change the source of the frequency, either the control panel which is the default (0 or 1, keys or potentiometer - dial, if that is available on the VFD), External analog signals which are the ACM, VI/CI and 10V/5V terminals in the VFD, or the RS485 which is a serial connection to the computer. You want to set this parameter to the External terminals which may be 2, but check your manual for the proper value.

I'm hooking up the VFD Controller to the USB controller to control the speed of the spindle. In your video you have the wire from the USB controller to the ACM of the VFD controller.

There are a number of differences, but the main difference is the use of steel rails with bearing blocks rather than using aluminum angle and v-groove bearings to serve the same purpose.

To use a touch plate on any controller, all you need is a conductive flat material with a known thickness and some wire and alligator clips. Solder a wire to the touch plate and connect the other end of the wire to the free input terminal of the controller. Connect a wire with an alligator clip to the ground of the controller (on the Mach3 USB controller, this ground is the DCM terminal, or the digital gnd on the 24VDC power supply). Connect the alligator clip to the end mill.

You can either use a script to serve as the probe, or you can use the ref all home button and setup the touch plate as a home switch.

The number of watts is not available for this radiator. The fan/radiator combination will allow you to calculate the watts, depending on the RPM of the fan but there are other variables as well that makes this calculation more challenging. The fan and radiator provided, with the flow of water with the pump provided are more than enough to cool a spindle within an environment that has an ambient temperature below 90 degrees.

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.

You can use two MGPs (bare MPGs) to provide independent axis control. The handwheel input on this controller contains discrete inputs for the X, Y, Z, and A axes. These inputs can receive a pulse to move their axis. For instance, you can connect an MPG to the X-axis pin and the wheel will move the X-axis only.

Of course, if you have a traditional pendant, you can move any axis independently from only a single wheel with a switch that selects the axis you wish to move.

The pressure sensor used in this controller does not have a specific resolution since it is analog; however, the microcontroller used in this controller receives the information from the sensor using an ADC (Analog to Digital) converter. The resolution through this process is 10-bits. A 10-bit number is from 0-1023 (1024 possible values).

The accuracy of the sensor is 1.5%.

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, a 4th axis can be installed on this machine. However, you will need to make the 4th axis at a different level than what the table surface is so you can maximize the reach of the machine and the size of the workpiece you affix to the 4th axis. One way to install a 4th axis would be to create a depressed portion of the table (like a trench) for the head stock and tail stock of the 4th axis. This depressed section should be large enough to provide for the typical workpiece clearance to rotate, and for the end mill on the spindle (router bit on the router) can reach the desired depth into the workpiece.

Torque is measured from the center of the shaft to the pitch diameter divided by 2 of the sprocket in inches or feet and is able to move (rotate) with a force at this measurement tangential to the pitch diameter circle. The smaller this pitch diameter is, the less torque is required by the motor to turn the sprocket under load. If you are starting with a large sprocket, say with a pitch diameter of 5 inches (2.5 inches radius), it is easy to reduce the size of the drive sprocket to increase the mechanical advantage. All you need to do is take the 2.5 inches and divide that by 3 to find the new pitch radius.

[107] What size gear could I add to your #25 design to increase torque by around 3x?

Absolutely. The mach3 USB will work in all versions of Windows and will also work in 32-bit or 64-bit mode.

If you have heard that Mach3 in general will not work in some versions of windows, it is because past controllers used parallel ports, and MAch3 needed to use a specific driver that only works under 32-bit mode. The MAch3 USB controller uses a traditional USB port, so you will have no problem with any version of Windows.

A safe depth would be the diameter of the end mill. If you have CNC experience, you can also use sound as a very good indicator of the sweet range of the depth. If you hear the spindle struggling, it's probably best to either slow the feedrate, or reduce the depth. The chip size is also important to indicate if the end mill is cutting efficiently. you want to make sure the chips are not coming out as dust. There should be some meaty chips.

I will typically push my end mills and use the full depth of the material if there is enough flute length to do so. If I hear the spindle struggling, reduce the depth by 10% or so.

There are so many variables and I would suggest starting with the chip load calculations found on this product page.
