I was looking for a MYJG80W power supply but I see you may not have the 220 volt version. Do you have these as yet and if not what can you advise on availability or where I may find one...Thanks

Stepper motors are known to make noises while function, however this does not affect accuracy or job function. However we recommend to check your wiring for solid connections, and for good connectivity!



On a personal note, here is one cool video dealing with making songs with stepper motors!

I bought and built the Blacktooth laser cutter. It works, but one of the stepper motors makes a loud static hiss a second after the CNC power supply is turned on or off, and makes loud tweets and twirps when running. It seems to operate fine otherwise. I was wondering if it was "going bad" or if that is normal?

Many shielded cables come in various materials and designs, so having one with a copper mesh covering the inner insulator wire is no problem. We currently use a extension cord found locally at a hardware store and include one 18G wire for ground. So a specific shielded cable is not a required, unless being used next to specific and sensitive electronics that are extremely sensitive to noise and voltage interference than a shielded cable is required.

I purchased a 2.2 spindle a while back and went to the electrical supply house to but shielded cable for the power run, I was on the web a while back and saw a picture of shielded cable that didn't look like what I had bought. should it have a copper like mesh wraped around the inner insulation. Thanks

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??

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?

We have ran across this issue on occasion, and usually results is there is something along your wiring that is causing a fault or is not getting good contact.
We would recommend going through the wiring thoroughly and checking continuity with the y-axis wires, going from your USB or Parallel BoB to the driver.

My CNC machine has suddenly started going in only one direction in the Y axis. It was working fine for several days and then started going in a single direction when I would do a manual job.

Did you connect the USB connector to the breakout board?

Additional Information:
YES I CONNECTED THE USB TO THE BREAKOUT BOARD

Click the link to add information to this solution:
I connected the electronics (for 2 x 4 feet) that I ordered from you. But how do I check if I connected all the wiring properly. There is neither any light on motor drivers nor on breakout board. And the motor shaft also does not move before and after the power supply is given.

The digital signal portion of the CO2 laser tube power supply has various terminals for signal power, signal gnd, laser intensity and engaging the laser (turning it on or off). The TL and TH are triggers to turn the laser power on or off. These may be labeled L or H on some laser power supplies. You can use either TL/L, or TH/H to control the laser.

If you use the TL or L terminal to control the laser:
If a low signal (gnd) is present at that terminal, the laser will turn on. If a high signal (5v) is present, the laser will turn off.

If you use the TH or H terminal to control the laser:
If a high signal (5v) is present at that terminal, the laser will turn on. If a low signal (gnd) is present, the laser will turn off.

You should first test the control signal from the interface with a multimeter to make sure the laser will be controlled correctly before powering the laser power supply

On the blacktooth machine wiring diagram for parallel breakout a wire goes from 6 on the BOB to TL on the laser power supply. My power supply has an"H" followed by a "L". Which is correct? I've connected to the "L" but the laser appears always on.

All of our controller will allow two steppers on any of the axes. Multiple stepper motors and drivers on a single axis is more a function of the way the stepper motor drives are connected to the output pins of the controller. To connect two stepper drivers to a single axis, you need to connect the output pins (dir and step) to each of the two stepper motor drivers.

Consider the controller on cost, features and how they are connected to the computer.

Out lowest cost controllers are:

Mach3 USB board - Has good features and uses the USB from the computer as the main connection
https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

Parallel Breakout - The computer generates the main signals and this board conditions the signals for the drivers. Although it requires the parallel port from older computer, the board has the most broad compatibility with control software out there including Mach3 and LinuxCNC.

Highest cost but most feature rich:

I am looking for a controller for a 3 axis dual Y stepper cnc machine. If at all possible I would like a list of the parts that will be needed. I prefer to go with an ethernet setup vs a parallel port.

Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

First, you should check the configuration in your CNC control software and determine if the spindle control pin is correctly set. That pin will engage the relay.

The P and O position of the relay is set as Normally Open where the relay is open (open circuit, or no connection) at idle and when engaged will be closed (closed circuit, or connected). If you suspect that the relay is damaged, the recommended action would be to disconnect the spindle from the relay and operate the spindle/VFD manually using the Run and Stop buttons on the face of the VFD (until the breakout board can be replaced).

The spindle has started on my Machine while the machine was sitting idol, I'm not sure if the relay has failed on the breakout board. Is there a way to test this?

The Mach3 USB interface card uses 5V (powered from the computer's USB) and a 24v to power the inputs, outputs and spindle control

the mach3 usb interface can be found here:

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

But the mach3 usb does not absolutely need the 24V supply. The 24v supply is only needed if you will be using limit switches (I1-4), VFD controlled automatically and for use with the outputs (O1-4)

The electronics for my current cnc machine has a 36v 8.8 amp power supply. Is this power supply sufficient to power my new Mach3 USB interface?

All USB boards, are tested and checked before shipment for all axis, and inputs. Here is a link with clear instructions on how to setup Planet-CNC (http://www.planet-cnc.com/faq/machine_setup/).

Please check continuity and for any crossover disruption when wiring your board, try to wire each as cleanly and with out crossing any live power wires and or motor motion wires.

I have a usb cnc driver board on your 1'x3' cnc and i cant get the z+ limit switch to stop the machine in the provided software. It registers the button but doesn't inhibit movement. inversly the button works when selected as '-' for negative movement.

Your deduction of the power supply at fault is probably correct. When you attempt to power the power supply, check the V+ and V- (COM) with a multimeter on the DC setting. You should measure 36 volts.

If there is no voltage on the V+ and V- (COM) there should be a fuse inside the power supply that you might want to check. Also, while you in there, check the electrolytic capacitors. Electrolytic capacitors have a finite lifespan much shorter than other components and are often the cause of many problems with all electronics.

Please let us know what you find.

My machine stopped today (after many fun filled hours of operation in the last 3+ years). I suspect the 36V 8.8 amp power supply as there is no power to the stepper motors. Is there a breaker to check, or do I need to get another power supply? Should I assume the stepper motors are OK?

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.

Click the link to add information to this solution:
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.

The drivers have quite a bit of protection, so you probably won't ruin anything. You motors are jumping and that is just the motors engaging from getting power from the power supply.

There could be many reasons your motors don't turn. Consider these troubleshooting tips:

- If you are using our parallel breakout board, make sure that the step pins are set for active low (config -> Ports and Pins -> Motor Outputs -> the steps pins should be enabled and set active low)

- The parallel breakout board is powered (connect the USB to the computer using a USB cable)

- In Mach3, make sure you have jog enabled (a little green button at thelower middle of the page in the program run screen).

My stepper motors stopped working all of a sudden. Mach 3 is running fine, just no signals getting to the motors. The lights on the motor drivers began blinking erratically when this started. Any advice where a problem like this can come from would be greatly appreciated.

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.

I have a home built CNC running Mach 3. I have power to all the motors and the breakout board but no movement when running g-code. I cannot even manually move the motors with the arrow keys or page up and down. It also has an integrated 120v receptacle showing an open ground. I don't know if all this is related.

I would first check the mechanical parts to ensure smooth motion. Is your machine bogging down during cutting or jogging/rapids?

You can increase the voltage to gain a higher speed for rapids/jogging, but make sure the driver can handle this voltage. There should be a max voltage on the driver label.

If the bogging down is happening during cutting, either reduce the cutting depth or switch out the drive and motor for the axis that is giving the problem.
