The Mach3 100 kHz controller may be able to support the Sherline 1/2 pulse mode, but I have not tried it. There is no information in the documentation that is related to the parameter that can be set in Mach3 for the Sherline 1/2 pulse mode. You may be able to play with the available kHz ranges that the plugin allows to see if there is a pulse width that meets the Sherline 1/2 pulse mode specification.

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!

No, the Mach3 USB controller only works with Mach3. If you wish to use Mach4, I would recommend this very feature-rich controller:

The Mach3 USB board found here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

Is not designed to work under Mach4. The Mach3 USB uses a plug-in in Mach3 to function as an interpreter, sending pulses and signals to electronics from commands sent to the board from Mach3. This plugin would need to be updated to be able to work under Mach4 but the board manufacturer would need to do this update. So far, there is no plug-in that will work for Mach4 and this board.

I will check with the developer of the board and show the response on this FAQ.

Additional Information:
The response from the developer:
Are you referring to using Pin 17 for the spindle speed control? Make sure that you set the desired spindle speed in Mach4 by executing S1000 in the MDI or the G-code.

Click the link to add information to this solution:
Mach 4 is not triggering PWM pin 17 on Pokeys57CNC. I am able to get it to work through the Pokeys app but not Mach 4. I've made all of the setting changes prescribed in the manual.

I don't see anything in the datasheet for the relay that indicates an overheat condition. While the relay is engaged, the power consumption is 400 mW and I don't believe this is enough to raise the temperature faster than the heat dissipation from the metal on the leads through convection or radiation outside of the rated temperature working ranges providing that you maintain an ambient temperature range within -40°C to 85°C (with no icing or condensation).

To use the PoKeys57CNC with KUKA, you will need to make sure that the servo drives will be able to receive pulses that are generated from their 8 step/dir signals.

The PoKeys57CNC Manual states:

PoKeys57CNC is a blend between general purpose PoKeys device and motor controller. The device is targeted primarily for controlling up to 8 STEP/DIR signal driven motors (stepper motors, servo drives, etc.)

Here is a link to the Pokeys57CNC Manual:

[244] Can I get the circuit diagram of the pressure controller?

The blackTooth is a laser cutter/engraver, and its current design directs the beam in 2 dimensions (X and Y) over the surface of a workpiece which is assumed to be lying flat beneath the laser head. There is no mechanism to move the Z-axis directly. There is likewise no direct provision to move either the workpiece or the laser head for a 4th or 5th axis of operation because that would change the optical path and/or the focal point. However, you could certainly add a 4th axis to move a workpiece beneath the laser head -- it would be an interesting project, and if you do it we would like to see pictures.

The ability of the software to support this addition depends upon which software you are using. If you are using a breakout board and machine control software designed for conventional CNC mills, such as Mach3, LinuxCNC, or PlanetCNC, then the answer is yes, the software will support the 4th axis quite easily. If you are using the integrated laser controller, the adaptation would be more difficult.

That's an insightful question. My initial impression suggests that it is indeed possible. The trigger for the plasma torch can be activated by a high or low signal, which can be conveniently managed using a relay. However, one potential challenge might be the absence of torch height control in laser controllers such as the Ruida. Nonetheless, if you can address this height adjustment through mechanical means, which many machines are capable of, utilizing the Ruida controller for plasma applications should not pose any significant issues.
