We recommend our electronics combo for the scratch build kit, which you can find on our site here: https://buildyourcnc.com/item/electronicsAndMotors-3axis-425-elcombo. This is our standard general purpose 3 axis electronics system, and includes (3) NEMA 24 425 oz-in stepping motors, (3) Drivers (3.0Amp 24-40 Volts, with 1-1/64 microstepping), (1) 36v 8.8a Power Supply, (1) Interface Board either USB or Parallel. (The USB version requires PlanetCNC software; the parallel interface board gives you a variety of options, Mach3 being one popular choice.)

I got the plans and hardware from you guys and im almost ready for the stepper motor part of this build. what size motors are good to use for this build? the size of cnc will be 2x4 when finish or what size will not work? thanks

What is the weight of the gantry, number of teeth on the drive sprocket and tooth pitch?

I build a 3 axis router CNC the gantry is heavy in aluminium plate, witch plug n'play kit you suggest me 1 or two motor on the longest axis this will be drive with chain?

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?

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?

I want to build a 4 x 4 plasma table. I am not good with the electronic parts of the system. What would you recommend as a turn key electronics package? I also want to build it with chain drive

You can find the datasheets to our motors be going to the the stepping motor category page https://www.buildyourcnc.com/category/nema and selecting the motor. This will bring you to the product page for the motor and all of the motor information will be found there.

I would like to design my own CNC router around one of your electronics bundles, either the 3 Axis - Heavy Gantry or 3 Axis - All Large Motors. Do you have the data sheets for the motors so that I can use the dimensions in my model?

As long as the bearing has a minimum thickness of 1/4" and 9/32" is a bit thicker, there will be no problem with the book build using the bearing that is 1/32" thicker. There is actually more surface area which is better.

I am building the CNC in your book - Build you own CNC Machine. One of the bearing thicknesses is 1/4" I can't find that bearing online. I can find 9/32, will that be a problem. Do you have a source? Thx

I have a 4' X 8' table with carriages that use nema 23 motors. I have a hypertherm 45 plasma cutter. I have 20 degree 20 pitch rack gear. Can you suggest a plug and run system that I can use for cnc plasma and cnc routing?

The bluchick CNC router is a perfect small format CNC that can handle most jobs. Please check here to see the latest information on this CNC router. blueChick CNC Machine. The machine can be purchased assembled. Al you will need is a computer and spindle.

I'm looking for a complete CNC router, out the box ready to use system. Computer and software. What do you suggest? I need a working area of 12"x24"

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?

Yes, absolutely. If you need two motors for a single axis, you will want to use the same terminals for pulse and direction from the breakout board.

More specifically, you will wire the step/pulse pin to both drivers, and the direction pin to both drivers. If the motors need to turn in different directions, simply swap the A and B coil connections on one of the motors.

Additional Information:
i have checked the cnc machine for any flex and there is none but i still cannot cut circles they end up square.have checked calibration and it is correct but if i run at 4000 mm feed all comes out correct but if i change feed to say 2000 mm it makes the part small, like in tiny.

I'm going to use 2 stepper motors for my X-axis. Can I use the same connections on the B/O board to do this knowing I will need 2 separate driver boards.

Have you considered reversing the A and B coils on one of the motors to the drivers? This will cause the motor to spin in the opposite direction. This is the easiest method. Using the HEX inverter is a more complex method and not recommended for simple driving tasks.

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 MOTOR SOUNDS LIKE SKIPPING STEPS WILL 651OZ REQUIRE A DIFFERENT POWER SUPPLY CONTROLER?

Dealing with our scratch Build kit/BYO CNC Book Kit, you will use our basic 3 axis electronics kit (https://buildyourcnc.com/item/electronicsAndMotors-3axis-425-elcombo). Now dealing with the Breakout Board, the book specifies the parallel port BoB, but you can use the USB BoB and use Planet-CNC rather than using Mach 3 or Linux-CNC as your control software.

Correct kit of motors and electronics, I bough a book in Amazons kindle to build a CNC, this book mention a kit of motors and electronics for parallel port, I want to use USB, can you suggest me the correct kit fot this machine.

You can use either 1" x 1" x 1/8", or 1-1/4" x 1-1/4" x 1/8" angle on the table sides. The BRAs should all be 3/4" x 3/4" x 1/8". The Y ans Z axes should use the 3/4" x 3/4" x 1/8" angles.

Click the link to add information to this solution:
In the Build your own CNC machine book, You said you use 1 1/4" angle on the main table but 1" would be better. So my question is Should I use 1" angle on the main table (4' length) and 1 1/4" angle for the BRA's and other rails?

The size of the stepper motor is measured in holding torque, generally oz/in. You will determine the torque loads of your axes when selecting steppers. Once you know which stepper you need, the drivers and controller board are simple to pair with them.

I'm trying to build my CNC router 3m*1.3m, but i'm not sure what is the type of stepper motor i should pay, all my CNC body is Al. I need to bay 4 Stepper motors, 4 drivers, spindle, inverter, and i don't know what is the type of controller ?

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?

Absolutely, I can answer this type of question and anything other questions you may have with your new-to-you CNC router.

[789] Can you help me with selecting a power supply ( and a few other components ) for the stepper motors that came with a homemade CNC Router I just purchased.
