Our CO2 laser cutters and engravers can cut birch plywood. Our 40 W lasers can cut birch plywood's at about a quarter inch. You will need a laser at least 80 W of power to cut that thickness of birch plywood. Our vertical laser XL would be able to handle that material.

CO2 lasers in general are not the best candidate for cutting thick woods. For thick materials, it is best to use a CNC router.

If you would like to replace a router that outputs a relatively low HP (horse power) such as the Bosch PR20EVSK or Dewalt 611, both having about 1-1.25 HP, the 1.5kW spindle would have more than enough power and will also provide constant torque where the routers are unable to achieve. The 1.5kW spindle outputs 2 HP and is water cooled to keep the dust out of the air!

Yes, you can use Mach3 CNC motion control software with Windows 8, but you will not be able to access the parallel port with this version of Windows and Mach3. If you wish to use Windows 8 and Mach3 together, you will need to use a USB motion controller like the one shown at the following URL:

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

To assemble the blueChick v4.2, you will need two sets of instructions, the assembly instructions for the main body and mechanicals of the CNC machine, and the instructions to connect and test all of the electronics.

The assembly instructions are located at this URL towards the bottom of the page (click on each picture to get a larger view):

https://www.buildyourcnc.com/blueChickVersion42CNCMachineKit.aspx

The instructions to connect and test the electronics can be found at this URL:

A #8 nut is a nut that is used as a pair with a #8 screw to mechanically fasten parts together that contain holes just larger than the #8 screw size.

The #1 to #12 designations are not the easiest to understand as they don't specifically inform of their size. The thread diameter of the #8 screw is .16" (the major diameter measured from the crest of the thread, not the diameter measured from the root of the thread). The minor diameter measured from the root of the thread would most closely match the inside diameter of the nut.

We supply the latest stable version of Mach3. If you want control software that is a later version than Mach3, then you will need to investigate Mach4 for your CNC Machine application.

All of our spindles come standard with a 1/4" collet. The 2.2kw, and 4.0kw, can be upgraded to a 1/2" collet with a separate purchase.

Yes, our 2.2kW water cooled spindles can accept the 1/2" collet size.

You can find the web pages that refer to the book at this url:

To determine the shipping cost of a machine (i.e. greenBull 5x):

- You can add the greenBull 5x to the cart by going to the machine page and clicking on the add to cart button

- In the checkout process, enter your address and then click on get shipping rates. You will be presented by a list of shipping costs to your location.

If you purchase the assembled machine (which we highly recommend since you are outside the US) the entire system is tested, so you will not need any replacement parts. We have used motors and spindles on our machines that work constantly and daily for many years. These items still work to this day.

We can supply all components related to CNC machines and laser cutters.

You will want a grease that can be used in high temperature and heavy load situations also called high load bearing grease. A simple google search will yield many results from which to choose. We plan to carry this product in the near future (by the time you read this, we may already carry it).

The table dimensions for the 4'x8' greenBull large format CNC machine is 55.25"x120". You can find this information at the URL:

The table dimensions for the 4'x8' greenBull large format CNC machine is 55.25"x120". You can find this information at the URL:

https://www.buildyourcnc.com/Item/cnc-machine-greenBull-v4-4X

For the 6'x12' greenBull table dimensions, the table width for the greenBull table must be 80.078" (6.67' or 203.398 cm) and must overhang the underside structure by 1-1/2" to make room for the rails and this overhang portion should be 3/4" thick. The length can be variable, but remember that the gantry takes up some of that space, so add about 34 inches to make room of the gantry and the connecting hardware for the roller chain on the four corners. We recommend if you want a full 12 feet of travel, the table must be at least 178 inches.

We are not selling the plans at this moment. You can get the book authord by James Kelly and Patrick Hood-Daniel which is the same machines we sold plans for in the past. Here is the Amazon URL for the book:

https://www.amazon.com/Build-Your-Machine-Technology-Action/dp/1430224894/ref=sr_1_4?ie=UTF8&qid=1483548108&sr=8-4&keywords=cnc+book

Are you referring to the book build?

To allow a 4'x8' stock to be used by a blackTooth laser system, you will need to cut the large sheet with a standard woodworking tool such as a hand saw, circular saw, table saw, jig saw, etc. Alternatively, you can purchase our very affordable 4'x8' vertical laser systems that allows a 4'x8' sheet stock.

Spindles are generally covered up to 1 year after date of purchase. We do not repair them in house, but we do work with our manufacturer to replace defective units. Generally if you have a defective unit covered under warranty, we will issue a replacement.

We provide a one year warranty from the date the item is delivered.

t might be a better idea to increase the circuit breaker above 20 as 2200/110 is exactly 20. You will not have a buffer there in case you need it. Alternatively, you can decrease the current draw of the spindle in the VFD programming process.

For our Hiwin rail, you can find the specifications at this URL:
https://www.buildyourcnc.com/item/mechanical-rails-HIWIN-Linear-20mm-Guide-Rail

For our standard round linear rail, you can find the specifications at this URL:
https://www.buildyourcnc.com/item/mechanical-rails-linear-guide-rails-20mm

You can actually set a current limit in in the VFD using the programming process and the specifications in the manual that came with your VFD. You can expect the spindle at 220 Volts AC to draw (using the standard formula):

For Volts, I will use 230 as the range is generally 220 to 240.

Watts = Current * Volts

Can also be written as:

Current = Watts / Volts

Current = 2.2kW (2200 watts) / 230 volts

Current = 9.6 amps



Assembling any of our machines will vary from customer to customer as it is a measure of the ability of the assembler. For the blackTooth laser machines, you should be able to have it assembled between two to four well focused days.

The specifications for the book build can be found on the flowing URL: https://www.buildyourcnc.com/Item/cnc-machine-scratchbuild

Yes, you can use a touch probe with our machines as it is really independent of the machine structure, mechanical components and motion electronics, for the most part. We don't currently sell touch probes, however, but standard touch probes for CNC machines will work fine.

We have always used water for our cooling, but since this is a heat transfer condition, you should be fine with any form of coolant.

Additional Information:
We live in a cool part of the USA. My CNC is in an unheated garage and temperature gets to -10 degrees Fahrenheit. So we use 100% anti-freeze that is used for winterizing campers. Use same coolant year round. Put 3 gallons in a bucket with fish-tank pump, and it works great. Since there is 3-gallons of coolant, no need for fans to cool the coolant. Just pump from tank to spindle back to tank. And no worry about frozen coolant.

Yes, if you want to bill the shipping charges to your shippers account as you may have negotiated rates, you can use the local delivery method at $0.00 (through the cart process) and call us to provide us your shippers account number.

Sure. You will need the proper mount for the laser tube and a mount for the power supply in relatively close proximity to the laser tube. If you have one of our greenBull CNC machines, you can use the laser/spindle head that we offer.

Yes sir. The holiday season has been brutal on us, but we are back in shape and answering all of our customer related questions. Please ask your question here on "Customer Service Live" or call us if you have an urgent matter.

CO2 lasers at the wattage we offer will not cut steel. However, if you are considering adding a spindle to the laser, then you can use that to cut the steel (similar to our spindle/laser combo head.

Yes, we ship to South Africa. To determine more details of shipments to your country, go through the cart process and use the get shipping rates button to determine if that country is served and at what shipping price you can expect.

Was there an opening in the tube upon arrival? Did the tube look like it was wrapped up by the shipper due to the damage that occurred? I am suspecting that the package was damaged by the shipper and the tube suffered an opening where the parts may have fallen out. Make sure to take many pictures of the damaged package condition so a claim can be generated.

Yes, I believe we can ship laser tubes to Ireland.

There could have been a small, slow leak in the tube, releasing the CO2 gas. The power supply could have also suffered from an electrical issue.

Yes, You can order, only you need supply the information of 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.

TIR specifications for the ER-20 collet used on 2.2KW Spindles is .0004 inches.

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.

Yes, we have a 4 axis combo kit available under Motion Electronics.

any CAM software that can import a DXF file and create g-code can be used to program a blackFoot CNC.

Every Lunar eclipse that falls on the extra leap-year day. When is the next one, exactly? Good question- I'll submit it.

All of our CNC machines are suitable for wood-working. It mostly matters what size you need (travel area).

The overall dimensions of the machine when mounted to a wall will be 119" from side to side and 25-1/2" inches out (from the wall to the longest part which is the bottom). Height of the machine (clearance) is about 76" maximum.

These boards are compatible with Mach3 only at this time. We will be adding a Mach4 board in the near future.

Spindles are generally covered up to 1 year after date of purchase. We do not repair them in house, but we do work with our manufacturer to replace defective units. Generally if you have a defective unit covered under warranty, we will issue a replacement.

We have used a 1600CFM air blower. You may not need that much power, but it is always better to be safe!

The VLXL does not come standard with a 1600 CFM air blower, but we do have them available.

100W and 130W lasers and power supplies can be equipped now, but we will have to special order them. Price point for the 100W will be estimated $150-$200 more than the 80W, and 130W $250-$300 more.

We have been quite busy during the Holiday season which is normal. This may result in extended lead times. If you would like to speak to a representative about your order please call 281-815-7701 or email customerservice@buildyourcnc.com and someone will advise you when to expect your order.

You will need a Z-axis mount for Spindle if you are currently using a router.

You will not be able to use a router mount for a spindle. You will need to get a spindle mount for your Z axis.

To add CO2 laser functionality to your existing CNC machine, you will need everything listed on this page: https://www.buildyourcnc.com/LaserComponents.aspx

The number of mirrors and mirror mounts will depend where and at what orientation the laser tube will be mounted in the machine. There is already a mirror mount in the head/nozzle unit, so keep that in mind.

It is possible to connect and configure the spindle VFD to the mach3 via an RS485 communication and protocol.

The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. You can find this file at the mach3 support forum here: http://www.machsupport.com/forum/index.php/topic,14182.0.html

You will also need to download the Microsoft .net 3.5 framework and install it: https://www.microsoft.com/en-us/download/details.aspx?id=21

Follow the pdf that comes with the library file, but here is a synopsis of what you need to do (I also added a lot more information that may be useful during this process as the manual does not cover the main connections that need to be done):

You will need to program your VFD so that it knows how to communicate with mach3 and the computer (go into the programming mode of the VFD and change these parameters):
- PD001 - value 2 - Enables with communication aspect of the VFD
- PD002 - value 2 - Enables frequency control from the communcations port
- PD163 - value 1 - VFD address
- PD164 - value 1 - Baud rate of 9600 (speed of the communication)
- PD165 - value 3 - 8N1 RTU - 8 bits (that's the size of the word that gets communicated), N (No parity or no error checking) and 1 (1 stop bit)

Copy the dll file to the PlugIns folder of mach3.

Connect the RX and TX lines to your computer. There are a couple ways you can do this, but the recommended way would be to use an FTDI USB device which converts a USB to a serial com port. The device will have Rx and Tx connectors to connect to the VFD terminals with the same labels. This method is recommended since serial ports are not as common in computers these days.

Next, you will need to configure mach3 to use the plugin library. Start mach3 and click on Menu -> config ->Config Plugins. Enable the new plugin by clicking on the red cross on the left column next to the plug in. Restart mach3 after doing this.

No you need to configure mach3 to use the HuanyangVFD plugin. Go to the ports & pins configuration and select the spindle setup tab. Make sure that the Disable Spindle Relays checkbox is unchecked. We don't want mach3 to output a signal for a relay since the spindle will start up and turn off within the VFD and not from an external relay.

Next, go to the HuanyangVFD settings by clicking on Menu -> plugin control -> HuanyangVFD. Set the parameters to the same settings you put into the VFD programming. The com port will be shown as new hardward when you plug in the USB FTDI device. A little bubble will be displayed at the bottom right where it will notify you that a new device is being installed (be patient while windows assigns a com port). Alternatively, you can use the windows device manager to see which port was set for the new USB FTDI device). You may need to restart mach3 several times until you get the correct information displayed in the PD001 and PD002 fields. When the com port is correct and the other parameters, like baud and VFD address is the same as you entered in the programming, then the PD001 and PD002 will show the number 2, otherwise, a 99 will appear which means that communication was not successful.

You can now control the on/off and RPM of the spindle using the RS485 communication between mach3 and the VFD.



Additional Information:
This looks easy enough, however, the VFD that came with my spindle is made by Huajiang, not a Huanyang. The parameter codes are different and do not line up with the ones offered in this response.

For in-depth information please call 281-815-7701 to speak to a salesman or email sales@buildyourcnc.com

Please call during business hours 9 AM through 5 PM Central Standard Time and you phone call will be answered. If it is not answered it is likely because there is another customer on the line. If you have left a voice mail, it will be returned once we are notified of it. Thank You

You can add a 4th driver to the 36v power supply to support a 4th axis.

Thank you for your feedback. Generally we are considered to be quite sane as a collective, although this can change from time to time.

We have a disclaimer on shipping rates, especially if you are ordering from outside of the United States, rates are generally shown only for air-shipments from USPS, UPS, and FedEX, which can be quite expensive. We do work with several freight and shipping companies that allow us to calculate options for lowering shipping costs. These companies do not generally have APIs that we can integrate into the website, so we need time to process quotes.

If the shipping quote you received from the website seems unreasonable, there is a good chance we can quote you a better rate. All you need to do is inquire with sales@buildyourcnc.com and we will make sure we get you the best possible rate.

The 80W tube is capable of cutting 1/2" plywood, but it would probably need to be multiple passes and would not be as quick as a Spindle cut.

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! (parallel: https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/)(USB: https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/)
Email(customerservice@buildyourcnc.com for further help)

The size of the stepper motor is measured in holding torque, generally oz/in. You will determine the torque loads of your axes when selecting steppers. Once you know which stepper you need, the drivers and controller board are simple to pair with them.

If the computer has been tested to be functional, it is most likely the breakout board which is faulty. Replace the breakout board and it should solve these issues.

We do not offer any military discounts.

All of our machines are a week lead time, other than the greenLean which is 2 weeks. Depending where your current location is,shipping will take anywhere from 1 week in the US, 1-5 weeks over seas.

If you need assistance please contact us by phone 281-815-7701 or by email customerservice@buildyourcnc.com

USB Mach3 boards will be available on the website now. Ethernet is still something for the near future.

As long as Mach3 orders are received during business hours they are generally emailed that same day.

If the products have documents available, they are generally found on the product page itself, somewhere in the description or under the instructions.

Unfortunately we do not have CAD models of our machines available to our customers.

The kits on eBay are generally older versions of the machine kits that came with less options.

If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

We sell HIWIN rail and Linear guide rail by the inch (cut to size) as well as the blocks individually.

We have sent machines everywhere across the globe and we can work with freight companies to get you a good rate on a shipment. Please email sales@buildyourcnc.com to request a quote.

the greenBull can handle cutting aluminum as long as the correct bit (end mill) is used and the bit is cooled frequently to prevent chips from melting and causing damage to the bit or warping the material.

We have electronic and mechanical components that can be used for lathe builds, but we do not have any specific kits or combos tailored toward lathe builds.

When software, or software license is purchased, we need to acquire the license, or software from the software developer and have it emailed to you. This generally takes one business day to complete.

We still use Mach3 with a parallel port. We are looking into newer boards with USB/ethernet communication.

I believe the country of Puerto Rico may need to be US instead. I will change the cart's country field tonight so that it reflects the correct value.

Additional Information:
I see that you used US and may have worked for the US postal department but I also noticed there is an exception for UPS. I will do further research and fix this issue for PR customers! Many thanks for your patience and persistence.

Additional Information:
I just completed some fixes to the cart that corrects the Puerto Rico address for USP and USPS. It appears that USPS and USP require differences in the way the country is designated.

Thank you for bringing this to our attention and please let us know if you are experiencing any further issues.

You may need to restart mach3 several times until you get the correct information displayed in the PD001 and PD002 fields. When the com port is correct and the other parameters, like baud and VFD address is the same as you entered in the programming, then the PD001 and PD002 will show the number 2, otherwise, a 99 will appear which means that communication was not successful.

You can now control the on/off and RPM of the spindle using the RS485 communication between mach3 and the VFD.

It is possible to connect and configure the spindle VFD to the mach3 via an RS485 communication and protocol.

The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. You can find this file at the mach3 support forum here: http://www.machsupport.com/forum/index.php/topic,14182.0.html

You will also need to download the Microsoft .net 3.5 framework and install it: https://www.microsoft.com/en-us/download/details.aspx?id=21

Follow the pdf that comes with the library file, but here is a synopsis of what you need to do (I also added a lot more information that may be useful during this process as the manual does not cover the main connections that need to be done):

You will need to program your VFD so that it knows how to communicate with mach3 and the computer (go into the programming mode of the VFD and change these parameters):
- PD001 - value 2 - Enables with communication aspect of the VFD
- PD002 - value 2 - Enables frequency control from the communcations port
- PD163 - value 1 - VFD address
- PD164 - value 1 - Baud rate of 9600 (speed of the communication)
- PD165 - value 3 - 8N1 RTU - 8 bits (that's the size of the word that gets communicated), N (No parity or no error checking) and 1 (1 stop bit)

Copy the dll file to the PlugIns folder of mach3.

Connect the RX and TX lines to your computer. There are a couple ways you can do this, but the recommended way would be to use an FTDI USB device which converts a USB to a serial com port. The device will have Rx and Tx connectors to connect to the VFD terminals with the same labels. This method is recommended since serial ports are not as common in computers these days.

Next, you will need to configure mach3 to use the plugin library. Start mach3 and click on Menu -> config ->Config Plugins. Enable the new plugin by clicking on the red cross on the left column next to the plug in. Restart mach3 after doing this.

No you need to configure mach3 to use the HuanyangVFD plugin. Go to the ports & pins configuration and select the spindle setup tab. Make sure that the Disable Spindle Relays checkbox is unchecked. We don't want mach3 to output a signal for a relay since the spindle will start up and turn off within the VFD and not from an external relay.

Next, go to the HuanyangVFD settings by clicking on Menu -> plugin control -> HuanyangVFD. Set the parameters to the same settings you put into the VFD programming. The com port will be shown as new hardward when you plug in the USB FTDI device.
