The CNC router build from book "Build Your Own CNC Machine" uses the basic electronics combo kit that includes three 425 oz-in motors is the kit designed for that machine. Here is a link to that electronics package: https://www.buildyourcnc.com/Item/electronicsAndMotors-3axis-425-elcombo

I am building the CNC demonstrated in your published book 'Build Your Own CNC Machine', 2009. You sell the 3 axis electronis combo, parallel, for $390. Is this the package from the book. Or are there other recommendations. Thank you, Hary Holstein

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

Looks like you are trying to screw me out of $30 plus tax as there will be no pdf files forthcoming unless I shell out another $255. Unless you provide the pdf files I will be forced to seek return of funds and will be notifying VISA, GOOGLE PLAY and the BBB doing so until I get satisfaction. If you are not going to honor your book title by providing complete usable information you should remove your book from the market place, or offer it for free. At this point I don't know how you justify screwing your customers like this, but this one ain't going to take it laying down.

For our parallel breakout board (https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/) the schematic will show the connections going from the BB to the drivers. The parallel breakout board uses the 25 pin parallel connection to communicate from the computer to drivers, and the USB is used to power the main-board itself, supplying 5V.

The electronics package I just bought from you (Book Build) is different from your wireing diagrams and video tutorials. Is there an updated wiring diagram available? Is the USB port on the breakout board connected directly to the computer USB to supply 5 volts? Thank you.

The greenLean vertical CNC is stable enough to handle large-scale production on a daily basis. We use 3/4" MDO plywood, which is equivalent to about 19mm. The gantry is designed to hold a 2.2kW Spindle, with a maximum of 24,000 RPM.

Hello. I like your vertikal router. Is then router stabil enogh for the need of a Carpenter? Are you using 21mm Plywood or 21mm MDF. What type of spindel (KW) is maximum allowed and whatbis the maximum feed (6mm cutter) in oak. Thank you, Veit

I would highly recommend a spindle and VFD rather than a router.

Spindles:
- Have a far longer life longer than a router. You will probably go through a few routers before the end of the spindle's life.
- Are quieter than routers
- And the water cooled spindles we stock do not blow the chips into the air. Chips are much easier to capture with or without a dust removal system.

You can find our spindles here:
https://www.buildyourcnc.com/SpindlesAndAccessories.aspx

Once you get your first spindle, you will never go back to routers. Routers are great for handrouting work, but not the best for continuous CNC milling.

Hi there, I have a cnc table that I built but I am looking for a higher powered router because I am using the table for flattening slabs with a large straight bit. Would you have any recommendations for the type of router I should buy? Also do you sell large bits for flattening slabs?

I purchased your book to build a cnc router, the plan drawings are indecipherable and text with them is illegible. There is a note to refer to MDF Parts Layout 1 PDF, MDF Parts Layout 2 PDF and MDF Plans & Cut List PDF downloadable from this site. Where are they I can't find them?

I need to know if you have prices for educators, or other ways that a teacher could procure a blackToe 2'x4' CNC router. I apologize that this is sort of a bold question, as your routers are already well-priced.

I'm not sure I understand the question. You are looking for spacers or sprockets?

Since you don't sell the hardware only package for the Blackfoot 4'x8' can you tell me what items I should look for for the chain sprockets, spacers to mount them to the 1/2" rod, and chain? All the other parts I can source from elsewhere

BUILDING ONE OF YOUR GREENBULL 6X LONG AND 2.2 KILOWATT SPINDLE DOES NOT FIT. SEEMS LEAD SCREW YOU SENT WITH KIT IS SHORT 42" LOOKS LIKE IT NEEDS TO BE 5 OR 6 INCH LONGER. THIS CORRECT? WHAT THE NEEDED LENGTH FOR UNIT?

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?

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?

Sure, email me at customerservice@buildyourcnc.com and I will send you a replacement for a minimal fee. I now use HDPE for that part. The HDPE holds up much better.

Building one of your greenBull 6X Long and 2.2 kilowatt spindle does not fit. Seems lead screw you sent with kit is short 42" looks like it needs to be 5 or 6 inch longer. Is this correct? What is the needed length of lead screw for this unit?

Yes, you can connect a THC, Torch Height Controller, with the Mach3 USB controller. The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

I am interested in using the Mach3 USB interface board. I was wondering if there was a way to run a torch height controller with this board for use with a plasma cutter, and if so do you know of any THCs that will work. Thank you.

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?

You will be fine with using 2 NEMA 23/24 (425 oz-in) and 1 NEMA 34 (651 oz-in) motors with the Woodsmith CNC build with a large heavy router with a 1/2" collet. Specifically, the Woodsmith CNC build uses lead screws for each axis and this will provide mechanical advantage allowing the motors along with the drive mechanics (lead screws) an increase in torque.

Building the 2'x4' CNC from the Woodsmith plans and want to use a router with 1/2" collet. Will your stepper motor kit with 2 NEMA-23 and 1 NEMA-34 be sufficient for a Bosch 1617 router motor, or will it be too heavy?
