THICKER MATERIAL OK TO BUILD THE MACHINE?

You will need to build the table unit for your machine. There are instructions on how to do this at the bottom of the product page here, https://www.buildyourcnc.com/Item/cnc-machine-blackFoot-v4
There is no estimate on how much this will cost though, since there are too many variables involved to do this.

- PC with parallel port and USB port
- 20awg stranded wires for the motors - http://www.buildyourcnc.com/electronicscombo.aspx
- 18awg stranded wires for power supply to drivers
- 24awg stranded wires for breakout board to drivers
(location and spacing of components varies from one person to another, so we do not provide cables/wires)
- General purpose extension cord (cut the female end off) to provide power to power supply
- USB cable to power breakout board
- Parallel cable to communicate to breakout board
- Router
- (optional - instead of router) Spindle with power inverter http://www.buildyourcnc.com/SpindlesAndAccessories.aspx
- (if purchasing spindle with inverter) General purpose extension cord (240v) (cut the female end off) to provide power to power inverter
- End Mill(s) http://www.buildyourcnc.com/ProductsEndMills.aspx
- CAD, and/or CAD-CAM software (to produce geometry, machine operations, and g-code) http://www.buildyourcnc.com/CNCsoftware.aspx
- CNC control software (to read g-code and control machine) http://www.buildyourcnc.com/CNCsoftware.aspx

This answer is applicable to most of our machines with the exception of the greenLean and the blueChick since those machines are equipped with a table structure.

I just wanted to know what I can expect to pay to build the blackFoot 4'x8' CNC machine, excluding computer, software and router? Is the kit complete or do I have to purchase additional items to finish?

BYCNC response:

Milling aluminum is no problem with our machines.

Here is a video we recently did with our 4'x8' machine. The aluminum piece is about 1/4" thick: https://buildyourcnc.com/tutorials/tutorial-greenbull-aluminum-cutting

The accuracy you will see from our our 2.2kW spindle is entirely dependent on the precision of your build, so it's not possible to say what level of accuracy you can achieve without an examination of the complete system. However, our spindles have a runout of less than .0001 in, which includes the collets that we sell. If you use a collet from another manufacturer, we cannot guarantee this TIR (Total Indicated Runout) dimension.

For the dimension drawing of the anti-backlash nut, please contact us directly by phone or email to techsupport@buildyourcnc.com

The actual cutting dimensions for our blackToe machine is 2'(24") x 4'(48"), the overall size of the structure built is a bit larger so that our customers have the actual size mentioned with each of our machines!

As long as the Ethernet cable is not next to stepper motor cables (between the stepper motor and the stepper motor driver) you should be fine. If you are using a spindle, make sure to shield the cable between the spindle and the VFD as well.

Additional Information:
One of my customers is testing this scenario. He is using CAT7 Ethernet cable which is double shielded. I/He will post the results when tested.

I would like to mount the CNC controller to the gantry and use the ethernet cable routed through the cable carrier, is ther ok?

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.

The blackTooth Laser cutter and Engraver can be built in a weekend. Take a look at the build instructions and try to determine if you feel you have sufficient capability to put together the laser system.

If you would like to use a spindle rather than a router on your existing CNC, we will send you another set of components that will allow the spindle to be mounted properly which includes the z-axis rails, rail support, spindle mounts and the dust shoe components.

Yes, we have the optional table for the blackToe, but we need to fabricate it, which only takes one day. We generally reserve one week for the total fabrication and packing of all parts.

The available options for the blackFoot, is only structural components with hardware, and structure components/hardware with electronic components.
