You will need to construct the table frame to your specifications and with a structure, fixtures and clamping to hold the timber that will be sculpted. You will also need the appropriate end mill that is designed to carve the timber. A dust extraction (vacuum) will be necessary to remove the dust and chips.

Hi, I intend on sculpting a surfboard out of a timber slab using the following kitset: greenBull 6x with Hybrid Laser/Spindle Head (includes Spindle/VFD and Laser Components) - USB Interface (Long Z). Will i need to purchase any additional items to have a fully operational cnc machine that is capable of carving the surfboard from a timber slab?

We do offer all of the parts; but it is best to purchase them a la carte. You will probably not want the hardware since this would not conform to a design in metal.

Hello, I'm interested in GreenBull 5'x10' CNC machine kit with 40W laser head. Is it possible to receive an offer for this size cnc machine kit with all the mechanics, electronics and laser parts, but without all the wooden parts? We would like to build this kind of laser cutter machine with metal frame and parts. And is it possible also to get 3D drawing for machine? Waiting for your answer.

The Mach3 USB will not work with Linux CNC. You can use our parallel breakout baord instead (if you have a computer that has a parallel port available).

Here is the link to that interface:

Hello. I'm currently building my first CNC router, and I'm powering it with a 3 axis electronics kit that was purchased through your site. I chose to get the Mach 3 USB Breakout board, but now I'm wanting to try to use Linux CNC to work with the computer I have available. Will that work with this board?

Depending on the type of motors and connection type, you could adapt your motors to work with our electronic packages, but you will receive additional motors since our kit is complete.

Now you will have to take into affect the actual motors you have and compare or get accurate replacements(Ex. our 425 oz motor(1/4" input shaft) will have to be same size or similar entry holes)

Your Controller board will be the major issue, due to its wiring and processing manner, you can view the connections for our breakout boards to compare with yours!

I am looking at one of your electronics packages as a replacement for my excisting electronics. I have a old table top CNC that has a bad electronics pack, but the motors, and the mill are in good shape. could your system be adapted to work in this case?

If you have an existing PC with a parallel port you will not need to purchase the onboard computer system on the blackTooth laser cutter and engraver. You will want to purchase the blackTooth laser engraver that comes with the parallel interface (breakout board). If you have an existing CNC machine that is being used with this PC, you can disconnect the CNC machine and connect the blackTooth to this PC. You will want to have two configurations for your control software.

Additional Information:
We have a version of the blackTooth that is 110v and 220v. We generally determine which is sent according to the requirements of the customer and in what country they live.

I'm interested in purchasing your black tooth laser engraver and am curious what setup to get. I already have a cnc wired via parallel port to my PC. Do I need to purchase the black tooth laser with the integrated computer or can I just disconnect my current cnc's parallel port and connect it to the black tooth laser engraver? Also is the black tooth 110v?

Sure, the USB interface has a place for 4 axes of limit switches.

Each axis can have two limit switches: one for the ++ (positive) end and one for the -- (negative) end. The positive end would be the limit switch at the end of the machine that, say the machine has a 4'x8' area, reaches a bit after the 8 foot mark. The negative end would be the limit switch behind the 0 foot location behind the origin. If the origin is in the middle, the negative would be at a little more than the -4 foot end and the positive would be at a bit more than the +4 foot end. Note that you can have more than one switch on each pin where the NC is connected in serial fashion and the NO is connected in parallel fashion (this can be seen on the diagram in the multiple limits switch section). The software configurations for the limits switches are under File -> Settings -> Limit.

A typical limit switch has three connections on it. These connections consist of COM (common), NC (normally closed) and NO (normally open). The COM would generally go to GND and the NC or the NO would go to the pin. If the NC is used, then the the switch is constantly connected until the switch is pushed (engaged) then the connection from the pin to gnd is broken (open). Use the settings in software to set whether in NC or NO configuration.

Let me know if this information was helpful (or not) by adding information to this question. Thanks.

User response:
Thank you very much for this helpful information. I'm still a little fuzzy on how the 6 limit switches physically connect to each other and to the USB breakout board. You've stated one switch (home) goes to positive and another switch (limit) goes to negative. Are all the GND prongs from all 6 switches connected to each other and going to GND on the breakout board, or no? And the NC prongs, how exactly are they connected to each other? And to the board? There has to be a diagram somewhere shows this visually, no? I don't know how to wire the switches in series or in parallel. I have already physically installed all the switches on the machine and ran the wires to where the board is. Now I just need to know where to plug these wires into the board. Also, taking into consideration that I'm using the Planet CNC software, the only settings I have pertaining to limit switches is "Enable/Disable" for each axis, and the actual limit for each axis. Nothing about NC or NO. Is that only in Mach3?
Thank you.

buildyourcnc response:
On the USB interface, the COM on the switch connects to GND and the NC or NO connects to the input pin (i.e. x++, y--, etc.)

Limit switch configuration is rather difficult to understand, especially with series and parallel. You can think of series as a single wire going from GND to the axis letter input terminal (i.e. X++ or X--). If the wire is broken, then the circuit is open (or the switch is engaged in a normally closed scenario). Normally closed is like an actual wire, and when engaged, the switch "opens" (breaks the wire). This is why we recommend in some systems that you can put many switches in series on a single pin. When one of the switches is engaged (breaking the connection) then the entire circuit of switches is broken and the machine stops.

In a parallel scenario, the state of the circuit is always broken until the one of the switches is engaged and the circuit is then closed or connected. The topology looks like a ladder. All the switches connect to both sides of the ladder and the switches are like the runs of the ladder (the horizontal bars that the feet are placed while climbing). Imagine all of the switches broken in this scenario (normally open). It would be like the ladder could be split in two, but if one of the ladder runs (switches) is closed by engaging it, then that run would connect both sides of the ladder and the two sides of the ladder would have a connection.

There is a diagram on the USB page of the various limit switch configurations. If you need more information (visual and/or otherwise), please let us know and we will immediately add that information to benefit everyone.

I purchased the original instructions about 3 years ago and successfully built that device. Now I am looking at the 13X36 Bluechick base kit. Will all my original electronics work with the new kit? Is there a parts list that you could send me for the 13x36 Kit?

You will need PlanetCNC software for the USB breakout board and when plugging in the USB the computer should automatically recognize the board, however you can go into device manager to see if the USB terminal is working correctly.
The parallel breakout board; the USB is not a connection terminal rather than a power source, and the parallel port will be the communication terminal.
The items you will need for a water cooled spindle would be: water pump, silicon tubing(length desired by customer), a extension cord(from a hardware store(orange))(1 same gauge wire/length as extension cord).

The Mach3 USB controller requires a minimum of 12V and a maximum of 24V to the DCM and 24V terminals. The DCM is the GND or DC negative terminal, and the 24V terminal is the positive terminal.

I bought the Mach3 board and am trying to connect it with an AMB 1400 DI router, which has a normal power supply (1400W) as well as a digital interface which has three wires: a brown wire (10-26V, power supply), a white wire (ground) and a green wire (0-10V signal). I'm no electronics guy--how do I connect the digital interface of the AMB to the Mach3 board?

if you purchased the USB interface, you will need planet-cnc software rather than Mach3, and you will need a usb cable to connect the usb interface to the computer.

The blackToe 2x4 CNC Machine Kit with optional table will need wire to connect the electronics. Don't forget to get some end mills to use for cutting the intended material.

If I purchase the [blackToe 2x4 v4.1 CNC Machine Kit - USB Electronics - Table Included] all I would need for this CNC to be fully operational is a laptop with mach 3 software and a router. Is this correct?

The pictures of the table on the blackFoot v4.3 CNC machine page uses 2/4 studs, a torsion box, and a final top 3/4" layer.

The torsion box and the top bed layer lays on a frame constructed by 2x4 framing studs angled to resist twisting and for greater rigidity. the joints are simply connected with long screws and you can also use framing plates/ties. The torsion box is constructed of 3/4" MOD stock and has a ribbing pattern spaced around 8 inches apart. The design is similar to this: https://www.buildyourcnc.com/ModularTorsionBoxTable.aspx

The top later is simply multiple sheets of MOD 3/4" thick to conform to the required final measurement.

The table top pictured with the blackFoot 4'x8' v4.3 CNC Machine Kit looks nice. I'd like to build one just like it. How thick is it? If it was made from multiple sheets, how did you make the butt joints?

With our current models, that is a no. However our machines have the ability to be expanded length wise to the customer's choice. So you can design a share table if you add the required length of chain and rails and design the table accordingly to your specifications.

Hi Patrick right now I have a parallel port cnc machine that I built in 2013 using the hardware and components I purchased from your website. I want to update my system by changing my current parallel port interface board to a Mach3 USB interface board from your website. Is the Mach3 USB interface board all I need to do this or is there other components I need to get. please advise.

The Mach3 USB interface card uses 5V (powered from the computer's USB) and a 24v to power the inputs, outputs and spindle control

the mach3 usb interface can be found here:

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

But the mach3 usb does not absolutely need the 24V supply. The 24v supply is only needed if you will be using limit switches (I1-4), VFD controlled automatically and for use with the outputs (O1-4)

If you already have a Mach3 license, you don't need to purchase another one. The license is connected to you rather than the computer. Mach4 is licensed to the computer, but you are able to have multiple computers for each license, and can be switched from one computer to another.

If you purchased the license from me, you can call (make sure to leave a voicemail), or email to get a re-issued license.

We can configure the redLeaf or redSprout to control the motor of a 4th axis. The driver we use for the motor on the 4th axis is our standard 3.0 amp driver.

Click the link to add information to this solution:
If I purchase the Heavy Duty redleaf system (651 oz-in motors) and your 4th Axis Tail Stock setup will you configure the 4th axis to the computer? Your site states the 4th axis add on is "for a total of 4 axes 425 oz-in motors only"

In all CNC electronics configurations, you will need the motor paired with its own driver.

If two motors/drivers are intended for a single axis and the motors need to turn at the same rate and in the same direction, then the two drivers for these motors should be connected to the same signal wires from the breakout board (step (CP) and direction (CW)) signal wires.

If the motors need to turn in opposite directions, then either one driver will need to have the direction signal inverted, or resolve the opposite direction through a change in the mechanical drive train (i.e. flip the rack on a rack and pinion configuration, or in a roller chain setup, have the chain ride along the opposite side of the drive sprocket).

How do I go about purchasing a redleaf system with 4 drivers, where the (y) and (a) driver are connected to the same signal from the breakout board? I'd also need them to rotate in opposite directions.

The redLeaf webpage contains a purchase option for an extra motor and driver. We can setup the redLeaf system uniquely so it conforms to your application (i.e. motors running in opposite directions).

I've built a machine where the y axis has (2) 425oz motors, x axis has (1) 425oz. motor, and the z axis also has (1) 425oz motor. Would it be better to purchase a redleaf system with 4 drivers? or can I just connect both y axis motors to the same driver for a total of 3 drivers?

Do you have any intention to upgrade to Mach4? If you will be staying with Mach3 for a while, then the Mach3 USB interface is fine. If you intend to change to Mach4, then I would go with the Pokeys57CNC interface.
