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.

in your book - Build you own CNC Machine. Can I use 9/32" thick bearing instead of 1/4" thick?

WE don't have an actual file that contains the instructions for the machines as they are a part of a larger database file that is queried during the product page's rendering in the browser. The best option would be to print the webpage on a printer and use that as notes.

I know this will not provide larger images, but you could use the paper version to write your notes while assembling the machine using the larger images on the website.

On the blackFoot 4'x8' CNC machine do you have the instructions under one file that I can download, I want to print them out and make notes as I am building the machine.

It sounds like you got a misprinted book. If you purchased it from us, please contact us directly for a replacement. If you bought it from Amazon or a third party, you'll need to contact them. General information about lead screws is available on this website and at buildyourtools.com.

Just bought Build Your own CNC Machine book. It is missing the chapter on lead screws that is described on page 181 at the end of Chaprer 16. Where can I get this info?

Yes, the plans are detailed sufficiently enough to produce CAD drawings. If you wish to create AutoCAD drawings from the plans that we provide, we ask that the information conform to the creative commons license established on this site.

Yes, we can make a redLeaf system that has all 6A drivers for use with the 651 oz-in motors. We can also wire the electronics in a way that two of the drivers will use the pins of the same axis so that axis will drive two drivers and motors.

I am building a machine that requires 2 steppers to drive the Y axis, can you make me a redleaf system using the 651oz steppers that will work for me?

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 see the component list on the hardware and plans machine (scratch build machine) since it is the same machine in the book:

I have just brought your build your own cnc machine book and it talks about PDF downloads. Where do I find them please ?

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?

The book (scratch build) will be able to cut at very high rates of speed, but the speed is partly determined by the mechanical setup. Cutting wood is generally recommended between 60-200 ipm depending on the end mill and spindle being used. The larger the end mill (with increased chip load capacity) the faster the feedrate.

If you are using a standard allthread, you will not be able to have these high feedrates. You will need to purcahse high lead leadscrews: https://www.buildyourcnc.com/item/mechanical-leadscrews-leadnuts-!5-5-starts-10-tpi

The stepping motors need to turn 13 times to travel one inch using standard allthread (1/2-13 TPI - threads per inch). The higher lead leadscrews shown in the link provided will move one inch with only two turns allowing the machine to move many times faster.

These speeds are especially important if you are cutting materials that have low melting points like aluminum and thermoplastics like acrylic, Plexiglas, etc. These materials require high feedrates and smaller depth per passes.

I just made the book build Cnc machine with the feed rate of 11.19 inch/min as suggested in book. Can I increase it to 20 inch/min? I have 2hp of router attached

If the pdf. files cannot be viewed please update your pdf. reader, also for the X Table End, There are two of these table ends on the machine, each an exact mirror of the other. You will need six (1/4") 2" screws to fasten this to the two table halves. The two holes on either side of the bearing seat require 3" screws to fasten the motor mounts.

I am building the machine frome the book. The measurements for the 6 screws that hold the table together are missing. The chapter seven addisional material on the your website has the measurements but they are unreadable. Can you send me a PDF of that sheet. The cnckit1-1.pdf file on your website also is missing the measurements. Thanks Joe

We are developing plans for our machine, but they are not completed yet. Please let me know if you would like to be added to our list of customers wanting plans. Thanks,

How do I get started I would like to build a cnc router. Making the machine I can do, but I am weak on cad,cam and mach3. I am thinking about a 4’x4’. Do you have plans I can buy?

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 am going to build a CNC 4x4 plasma table. The frame is made of 1 1/4" pipe and the gantry will be made of either 2"x 2" or 2"x 3" tubing. What size stepper motors do you suggest?

The cutting area is 20" x 40" for the book machine. This area is determined by the 2'x4' sheets that make up the bed of the machine. You can increase this area if you use larger sheets and adjust the gantry width by the same difference of the width of the sheets.

You can also use the plans from Woodsmith magazine to build a larger machine.

Use a clamping collar (if you are using an ACME lead screw) or a couple of 1/2 nuts (if using an allthread) against the bearing to keep the bearing in place and make sure there is no axial play.

How do I secure the non-motor end of the lead screw for my 'Book' machine build? Does it just sit inside the bearing or do i use a nut to lock it in place? I did not see any instructions for this in the book.

Book build (scratch build), feedrates and recommendation.

Using standard allthread will provide around 20-30 ipm using 36 volts. Although it allows for a working CNC machine, the RPM of the spindle/router will need to spin at the lowest setting to provide the beat efficiency and life for the end mill at 1/4" cut diameter and higher. The speeds may be fine for smaller end mills.

If you would like faster speeds, you should change the lead screws on the CNC machine to the 1/2" 5 start 10 TPI which translates to 2 turns per inch which means, the stepping motor will not need to turn as fast to produce faster motion. That is to say, the stepping motor will only need to turn two revolutions for the machine to travel one inch and with the allthread, the stepping motor will need to turn 13 times to reach one inch.

Link to the lead screw and other mechanical parts needed:
https://www.buildyourcnc.com/CNCMachineMechanicalParts.aspx

To change the lead screws you will need (for each axis):

1. The lead screw for that axis.
2. Two 1/2" collars to keep the lead screw axially stable.
3. One Antibacklash nut.
