Do you have the Pokeys57CNC connected to a 24V external power supply?

Additional Information:
Yes, a 24V external power supply with the jumper positioned. I'm using the ethernet port so the 24v is the only source of power. I plan to measure the amp draw when I have a chance to see how much the vfd is drawing on the analog out.

Additional Information:
Further information. The resistance across the terminals on the vfd is 22k ohms. With an independent 0-10v current source I can run the spindle from 20 to 400 Hz. The PokeysCNC only gets to 3.8v with the vfd attached (and the vfd is at 150 Hz) compared to 10v when the vfd is not attached. The power to the PokeysCNC is steady at 24.18 V, so I'm not maxing out the power supply. Still looking for thoughts on what might be going on?

Additional Information:
And the other thing - The measured amperage is 0.17 mA for the 0-10 V signal (which makes perfect sense for 3.7 V and 22k Ohms).

Additional Information:
Just to bring finality to this issue - I added a 2.2 microfarad capacitor across the 0-10V input terminal (from signal to ground). This solved the issue. Evidently, it was an electrical noise issue.

My pokeysCNC board creates and analog signal of 0-10V for 0 to 24000 spindle rpm just like it should from Mach3. However, when the spindle is on, the voltage only gets to about 3.8V for 24000 rpm. It seems like the vfd is drawing more current than the pokeyscnc analog output can produce. It there an easy solution to this problem?

It sounds like the meter red and black wires are being switched around. The breakout board should not be giving you a -5 volts. The voltages should be in the range of 0 and 5 volts. The voltages will change when you move the axis in one direction or the other.

I have an issue about the breakout board , i can't understand why i get ( -5V) instead of ( +5V) when i measure the voltage between the "Dir" pin and " com" pin

Does the machine move smoothly when using the keyboard to jog the machine?

Additional Information:
Sorry it took so long to respond. Yes the table moves very smoothly using the keyboard. I try to reinstall of the drivers but it still moves very jerky with the MPG, sometimes moving back-and-forth.

Hi I recently replaced my parallel port breakout bored with a USB breakout board, Motors Earl working properly but my wireless MPG is not working properly, it is jerky when to try to move across the table, is there a setting that I missed?

Here is how to connect your router to the parallel breakout board through the on-board relay. You will need a spare extension cord. You will need to remove a portion of the outer jacket of the extension cord to expose the white, black and green wires (white = neutral, black = live and green = ground), understanding that the neutral and live create the completed circuit.

See this image of a similar connection. The terminal has the same connections.

Image of the relay terminal:
https://www.buildyourcnc.com/images/breakoutboardrelayNONC.PNG

The live/black wire would be cut and one end of the cut would be secured into the P terminal and the other cut end would be secured into the S terminal. The live and ground wire would be uncut and travel from the plug to the router.


Additional Information:
You can also connect other high powered devices to the breakout board using any of the output terminals. You will need to supply extra relays like the one shown here:
https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

Or you can find SSRs (Solid State Relays) that will accept 5v to drive the relay coil. Make sure the SSR will protect the 5V line from Back EMF as there is a coil in the relay. The one we sell contains a fly-back diode to protect the 5v terminal.

I have your breakout board with relay parallel port , I have a vacuum, light on router and air pump I want to also hook up to board, can I hook those up to board and also could I had reylays to each one, what is the best way to figure this out any information would be great. Thanks

You can test the power supply, but you will need to take extra special care since the voltage on the high tension line can be lethal. Go to this instructable to see all the step on testing the power supply:

can I purchase just the parallel controller board? I purchased the usb option 4 axis combo and would like to also try the system with my parallel port computer. Any help with this will be greatly appreciated; my goal is to implement mach4.

It seems to be getting some kind of interference or a short within the wiring or communication, try jogging the motors in the software without anything wired to the board. Then add one motor at a time to see if there is a short within your wiring or a faulty driver/motor.
If the USB breakout board continues to move the x-axis with no motors or driver wired to it, please email customerservice@buildyourcnc.com for a replacement or further troubleshooting.

Attaching two motors in parallel is possible, but you will need another motor and driver for the opposite side. Each motor must have its own driver to work accordingly and fluently. The two can be wired together, to the same pins on your breakout board and set the dip switches on the driver to match the ones on your x-axis(ex). But remember to view the orientation of the motor and which way it spins, since it is on the opposite side it will have to be orientated correctly to move in sync with the other motor.

I just finished building my first CNC with the electronics I purchased from you and I am already thinking about improving it. I would like to build a 2 motor X axis solution. Is it possible to attach 2 parallel motors and drivers to the BlueBrew Breakout Board? If so, how?

Is this regarding the Mach3 USB controller?

I'm having a problem with my controller card: I can measure 24 volts going to the card, but when I set Mach3 outputs I reagister no voltage. Please help

The board layout is different and the terminals have slightly different names, but the two boards function the same. The wiring diagram is the same for both boards. The plug-in driver for Mach3 is also the same, so you should not have a problem. If you do run into an issue, please let me know here and I will help you determine the problem.

Thanks

Additional Information:
Thank you for the assurance that the boards will function the same. You did not answer the primary question of wiring. The diagram shows a board with a 5V for each axis, the new boards have only 1 5V point on the axis side. In retrospect since this controller receives information and most possibly the 5V signal directly from the computer leading to the drivers. I will wire the X, Y and Z axis to the single 5V point and see what happens.

received my mach 3 USB breakout board today. The layout of the board is different from your diagram which shows a 5V power slot for each axis. Do I wire the 5V slot with only one 5V wire from one of the drivers or perhaps wire all three 5V wires into the one 5 V slot. Please advise.

You can add a limit switch to either the USB or the parallel board. Please refer to the product pages for these items to view wiring diagrams.

When wiring the limit switches to our BoB(breakout board), depending in the older model or our revised version (https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/0/), the older version will need the COM (limit switch) connected to 5V and the NO/NC to your input pin, but with our newer version you will use GND(ground instead of 5V) to common and the same for NO/NC but the setup in the mach3/confi/ports&pins/ is still the same.

Here is a tutorial where you can see how to set up the limit switches correctly (with our older parallel BoB): Part 1:(

I am attempting to set up limit switches on the 5 axis parallel breakout board that came with my BlackFoot kit. The output pins are driving the motors perfectly, but I can't figure out the input pins. With one lead in the 5V pin and one lead testing the input pins, my multimeter reads 0V for all of the input pins. Shouldn't those circuits be +5V? Where am I going wrong?

The parallel breakout board has the db25 connector for data and the USB connector for power. Connect the USB from the computer to the parallel breakout board so the breakout board will have 5V of power coming from the computer. The db25 connector (connector with the 25 pins) receive data signals for each pin from 1 to 17 and have respective numbered screw terminals, some for input and some for output (18 to 25 are gnd pins).

The parallel break out board on the Blacktooth machine has the parallel 25 pin socket, and also a usb socket. Should this usb socket be connected to the computer's usb port as well as the printer cable being connected to the printer socket?

The RNRMotion driver will not conflict with the mach3 license. Make sure you have the RNRmotion driver in the plugins folder and the provided xml in the main mach3 folder. Also, make sure to have the mach3 license file in the mach3 folder. If you still experience problems, please give us a call.

I am using USB breakout board with planet-cnc software. When I enable jogging keyboard x axis starts to move by itself (whether keyboard connected of not). When I press stop - it stops for a moment and then starts to move again. What could that be? Tried to reinstall software - did not help.

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.
