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.

I have one of your smaller stepper motors running my X AXIS bridge crane and if it is moved to fast the stepper motor sounds like it is skipping steps will the 651oz stepper motor require a different power supply and controler?

will the 651 oz. stepper motor you offer require a different power supply then for the original stepper motor I perched from you a few years back? I think it was a 24 V. unit????

This is most likely a wiring issue. I would disconnect all of the power to the drivers and reconnect one at a time to isolate the problem.

Additional Information:
that was not helpful. I already did that way before submitting this question. there are not that many wires here and I have already rewired this a few times. I actually think its a software or interface board issue because it does work sometimes but then trips (possibly a amperage / voltage issue) I am using the interface board that has a parallel port and usb for 5V. are there different settings that I need to setup?

I'm using the big 651oz in stepper motor for X and Y and the smaller 325 for the z and X and Y keep tripping when I try to tune the motors on Mach3 but Z seems to work. I have to turn power on and off to reset....is this a wiring issue?

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?

Recommend first test to check a non-working axis, is to connect the current working axis(ex X-axis) to either the y/z axis to test the actual board and wiring in other axis setup. If tests failed and working (x-axis setup) does not working in the new axis location, go the Planet-CNC/File/Settings/Axes and check if your current non-working axis setup requires a inverted pulse. Check box and test again.
Next test if first fails, is to check continuity in your wires. A simple multimeter(ohm's) will work, just connect the positive and negative ends to one side of the same wire and if reading comes to 0.000, wire has continuity and if reads 0.L then there is a break in the wire and should be replaced.

I installed the USB CNC Planet and got out of your USB controler $ 75 .Viska have linked to a video 'Party - 2.. X - running and y and z-axis does not work, it moves step motors and controller positions X -axis works, and Y and Z does not work.

This sounds like a problem with the step (pulse) signal. The driver motors receive two signals from the computer via the board -- one is high or low and tells the motors which direction to turn, one is a square wave pulsed signal(quick that tells the motor to turn or a constant high signal that tells the motor to maintain its position. With an oscilliscope you can check for proper signal at the board. If you bought the board from us, please contact us to arrange a return authorization.

Have checked stepper motor wires dozens of times and they are wired like diagram says. Stepper motors will not turn under power. I am using laser control option. What should I do?

The 8 wire motors need to be wired in bipolar parallel configuration. The wiring is as follows: Red and Blue to A+, Yellow and Black to A-, White and Brown to B+ and Orange and Green to B-. To find the wiring for the 4 wire motors, the wiring is Red to A+, Orange to A-, Blue to B+ and Green to B-.

I have constructed the cnc router machine as shown in woodsmith magazine. I have purchased the 3 Nema stepper motors. The one larger motor has 4 wires, as do the other two. However, on the schematic, the Z, and Y axis motors indicate 8 wires each. Did I go wrong, or are there different Nema 23 motors?

All you need is a CNC controller like the following options:

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

This controller is easy to connect using standard wire screw terminals and works with the mach3 control software.

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

This controller is a little bit more difficult to connect, but is a more feature-rich controller and will work with both mach3 and mach4 CNC control software titles.

Specifically, a CNC controller connects to the computer via a USB cable and connects to the motor drivers. These controllers also connect to the limit switches, spindle/router control, air/fluid/mist control, etc.

Hello there, I am a beginner in trying to control a stepper with a pc, you can sell me a kit to control my motor from the pc. I already have a motor, driver, and power supply

Since you mentioned there is a nasty smell, I'm wondering if there might have been a issue with the power supply. Can you email us your name for the order and specific voltage you are using for the redFly? at techsupport@buildyourcnc.com. Also I want to mention if you have the USB cord plugged in to the redFly if it has the parallel interface board?

When I first hooked up my redFly and was manually testing all the axes, everything was going well, then my Y axis stopped working all together, and now my X and Z have stopped also and my redFly has a nasty smell coming from it and none of the stepper motors seem to be getting power.

The blackToe 2'x4' cnc machine is sold as a kit only. We offer plans for the scratch (book) build machine that can be found here for purchase and also comes with a DVD showing the build process: http://www.buildyourcnc.com/cnckitintro.aspx and the plans for build in the book is on the CNC book page: http://www.buildyourcnc.com/Book.aspx.

You can use the same size stepping motors referenced in the book: http://www.buildyourcnc.com/category/elcombo

I would like to build the 2’x 4’ blackToe2x4v40 CNC router. I have your book. I want to build the latest model blackToe2x4 v40. Are those the correct plans on your web book page ? Is there a bill of materials? If I use a Porter Cable 3-3/4 router motor what size stepper motors do I need?

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.

No, the 3.1 version will not support slaving the X axis. You will either need to wire the two x axis driver to the same X signal pins, or use the DDCS v4.1 which does support slaving an axis.

[823] I plan to use a DDCS stand alone controller for a CNC router build which will have two stepper motors on the x axis, one on Y and one on Z. Will the 3.1 version handle two motors synched on the X axis or will I need the 4.1 version?

We may be able to source those motors. Curious, the 6000 oz-in motor is pretty big. Do you mind explaining the application of the CNC machine and the structure that would require the large motor?

The largest motors we can offer is 3900 oz-in without any mechanical help. 6000 oz-in can be resolved by mechanical means as an alternative.

I am converting a 12x36 lathe over to CNC, I am interested in a 2 axis kit. I would love one stepper motor to be no smaller than 1200oz. , and another at 6000z. Is this something that you could offer? I have two other cnc machines but this is my first converstion on my own.

The 2.5 amp driver can only accept a power supply between 12 volts and 24 volts. If a 36 volt power supply is used for this driver, the main driver chip will exceed its maximum voltage rating and cause failure.

If you need to spin your motor faster, you can either use a more appropriate driver (i.e. 3.0 amp driver) or you can change the mechanical parts so the axis has faster travel.

Can I connect a 36V power supply to 2.5 AMP Stepper Motor Driver. On the actual driver it shows 12V - 24V, but in the description and data sheet it indicates that it can accept 8V - 45V. Will I benefit from more powerful power supply. Thanks

ABSOLUTELY NOTHING WORKS. I HAVE ALL STRUCTURE AND MECHICAL PARTS OF THE BLACKTOOTH CUTTER DONE. HOWEVER WHEN WIRE UP STEPPER MOTOR TO DRIVER. THAT MACH 3 USB CONTROLLER BOARD, TRY JOG MOTOR, WORKS! PREVIOSULY HAD PLANET CNC BREAKOUT HOWRVER, ONLY MOVED MOTORS IN ONE DIRECTION COULDNT CHANGE IT. ANY HELP WOULD BE APRECIATED

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.

In the BlackTooth instruction the concluding sentence suggests connecting a wire from the right terminal of the pot to the VCC on the Laser Supply. There is no VCC on the power supply for the Laser that I can find. So, does this wire go to a different terminal on the power supply, or somewhere else where VCC exists, such as either stepper motor control?

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.
