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

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?

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:

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.

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

No, the greenBull CNC will function with the same performance in 110 or 220 volts. When the voltage changes, the current compensates for the different voltage. Make sure to select the appropriate products for the voltage. If the product does in list the voltage, make sure to give us a cal to inform us so we can supply the correct components in the package for shipping.

If I use your greenBull CNC with 110 instead of 220, am I taking a reduction in functionality?

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.

The PlanetCNC USB software, like most machine control software, can be used to control a laser engraver/cutter. The typical modification is to use the Z axis down signal to fire the laser, analogous to an endmill cutting into the workpiece from an initial position above it.

For the second question, it is important to note that BYCNC machines are not based on PlanetCNC software, or any other particular machine control system. The machines themselves will accept standard signals from a wide variety of machine control systems, not just PlanetCNC or Mach3. This allows maximum flexibility for the customer to choose their own preferred software for this part of the toolchain.

That said, our machines will accept a laser head either in lieu of or in addition to a spindle. Here is an example of a combination spindle/laser mount for our greenBull machine: https://buildyourcnc.com/item/cnc-machine-laser-spindle-combo-head. We have all the parts you would need to add laser functionality to your machine here: https://buildyourcnc.com/LaserComponents.aspx, if you feel comfortable assembling your own package. Also, feel free to contact our sales department for a quote if you need a custom assembly.

Yes, you can send your electronics to us for repair, or retrofit to work with either Mach3, Mach4 or LinuxCNC. You can send us an email at customerService@buildyourcnc.com to set up your appointment.

Some of the types of CNC electronics we will consider.

- We will work on electronics from other manufacturers as long as you are ok with the Mach3, Mach4 or LinuxCNC control software for your CNC machine or CNC router.

- We will repair or retrofit used CNC electronics.

- Some customers find that electronics are overwhelming to put together so we will finish these electronics wiring and assembly for you.

The cost for these includes labor cost for the time it takes to finish the CNC electronics repair or retrofit and for any parts that need to be replaced or added.

Here is an example of CNC electronics that we worked on for a customer:

We offer as much information as possible about the design and building of CNC machines through this website and the forums at buildyourtools.com. We also still offer our "scratch build" plans at https://buildyourcnc.com/item/cnc-machine-scratchbuild, where you can order the plans and DVD to build your own machine with or without the necessary hardware components.

Our technical support staff are occupied full time assisting customers who have bought complete kits or assembled machines, and unfortunately do not have the resources to provide one-on-one advice to individuals.

These files are no longer available. We suggest purchasing a kit, like the blackToe, or blackFoot as these kits are far more rigid and perform much better.

Would you be able to provide .DWG/.DXF files instead of .NC files for the CNC Routing Machine Kit Version 1.3 please?

BYCNC Response:
The book build was intended to be 20 inches x 40 inches. Larger machines were designed after the book build was introduced so customers would have the option to go bigger than what the book offered. Check out our larger machines on the website as the machines sizes range from 1 foot x 3 feet all the way up to 6 feet x 12+ feet.

User Response:
I'm not wanting to spend $3,000+ on a machine, I want to build one that will do a 4x8 sheet of wood. Will the plans in the book scale up?

BYCNC Response:
It is possible to scale the book build up, but the rigidity of the gantry would be questionable at that span, even if the height of the gantry structure were to be increased. The gantry design would need to be modified to become a box shape rather than a flat configuration. The kits on the site were design for those wanting a larger machine.
