Hi! I am interested in the blacktooth Kit. I live in UK. Is there any possibility of decrease the price of the shipment or do you know maybe an UK based kit provider? Thanks.

The greenBull 4X comes with all of the components and electronics to assemble the gantry of the machine. You will need to build the table. We provide the rails and roller chain for the X-axis (along the length of the table for full 8 feet of travel). You will need to provide some wire to connect the electronics and a computer to run the machine. You will also need to purchase the software that you will need to run the machine that matches how you will apply the machine. We suggest the mach3 control program. The CAM program is up to you as there are many options out there.

I am interested in buying the greenBull 5X Long Z CNC Machine Kit, but it is not clear for me what is included in this kit. Is there anything else I need to get the machine work?

There is a multitude of methods to create the table and frame for the greenBull long-z CNC machine, as some of the illustrations are shown on our gB webpage.

The image with the hollow mid section, is a custom table that will take advantage of the entire long-z axis assembly. So the frame can be built in that manner, however the CNC table should have its 3/4" table top. So you can cut standard sheets of wood, aluminum, plastics, etc.

So that specific illustration is not needed, however if you plan on cutting at that depth then it will defiantly benefit you to have that frame as shown in the illustration!

Can you please clarify what a long Z axis table should look like? I've built a frame that matches the dimensions on the GreenBull page but under long Z it says a custom frame is required made out of steel, which I did. But do I need to have the frame open like shown in the picture or is that just showing what the table looks like under the 3/4 material?

The 2.2kW Spindle has many advantages over a standard router such as the Porter Cable. The most obvious benefit to the user is the significant reduction of both dust and noise.

Additional Information:
What size water source is needed and how long can it be used before it is too warm? Do you have a pressure vs. flow curve for the spindle so I can properly size the water pump?

Additional Information:
I used a small pond pump inside a 5 gallon bucket. I put a little bit of windshield washer fluid in with it to keep anything from growing in it. It's worked great. I've had 1 hour run times with no noticeable increase in spindle temp.

I am interested in buying the 2.2 kW spindle. Does it run much quieter than a 2 hp Porter Cable router? You also mention a pump with a bucket of water. How long until the water is too warm to cool the spindle?

I can provide a drawing for that part or I can sell you the part of the machine that you need. Just email me at customerservice@buildyourcnc.com with a description of the part you need.

How can I get a replacement part for my Green Lean machine that i cant order from the Stuff For Sale page? I need the bearing truck plate for the Constant Force Spring. Or is there someplace I can get a drawing of the part so that I can make one?

Yes, you can connect a THC, Torch Height Controller, with the Mach3 USB controller. The THC uses the inputs to determine if the z axis needs to move up or down according to the arc of the plasma torch. The THC connects its outputs to the inputs of the controller so the controller will be informed of the states of the plasma torch.

I am interested in using the Mach3 USB interface board. I was wondering if there was a way to run a torch height controller with this board for use with a plasma cutter, and if so do you know of any THCs that will work. Thank you.

The firmware update for the USB board is done by PlanetCNC. with your board hooked up to the computer via USB cable, log into PlanetCNC. Then, from the Machine tab on the toolbar choose firmware from the drop down and click on update.

Is there a firmware update in the last two years for your USB board? If so how do we get it and install? If not do you expect any updates? If updates are released how do we find out?

All of our machines exhibis radial loads on all of our bearings with the exception of the bearings on the z-axis lead screw that holds the lead screw in place. These lead screw bearings are held between a coupling and a collar and the load on these bearings are well within their specifications.

The v-groove bearings that are used for movement along rails have load centered between the double races of the bearings (from where the point load from the rails exist within the center of the "W" profile of the bearing). There may be slight axial load on bearings on the z-axis positioned on the rails for z-axis up and down movement and y-axis side to side movement where torsion load exists from load on the end mill during the milling process; however, this is a very small fraction of total load on these bearings are are well within specification.

Can you let us know where you see side (axial) load on our bearings, so we can better describe the conditions? Thanks.

I've been interested in your machines, but the designs seem to side load most of the v-bearings, which raise questions about bearing life, and reliability. Isn't there a better choice of bearing configurations?

For the blackTooth laser cutter and engraver, it is not possible to lengthen within its existing enclosure dimensions. The cable management is a bit tight. Call us to discuss.

Dealing with our inverters, they are built with a bit of margin on the input power. For our 220V VFD the margin is from 170-250V 50/60Hz, so running our VFD in your location will not be an issue! Our electronics will not have a issue running at 230V as well.

Hello. I am interested in the green bull 6X long z CNC machine with electronics. I live in NZ, where the voltage is 230 V and 50 Hz. is it going to be possible to get the inverter to run here? Thanks!

Yes, if you want a laser on the machine, I would highly suggest that the laser be mounted on a separate gantry, similar to the following image:

You would need to develop the gantry structure, but you can use this thread to work out the design with my guidance.

You will need a laser tube, laser power supply, laser controller, mirrors, mirror mounts, lens and nozzle. You will also need some mechanical parts and some motors, drivers and power supplies for the drivers and the controller.

it is possible to install 2 motors on a single axis but you will require another driver and motor, but wire it directly to the same pins on your breakout board. Also the orientation of your motor since it is opposite side of the original so getting it to move accordingly to the original motor it will need to be orientated correctly. The slight shift could be the cause of the rod not being completely flat where the set screws are suppose to tighten the sprocket to the rod, so sanding it to a flatter surface might fix the shift in directions.
Currently do not have a kit or schematic available.

I am interested in your Black Toe (24" X 48") machine, and am wondering if using two medium motors on the "X" and "Y" axis makes sense relative to power and alignment (racking). What would you recommend?

The blackTooth machine, as it is designed cannot be modified easily as the box within which it is contained also serve as its structure. We are currently designing a special mount for the greenBull (for the 40 watt tube) which will provide 5'x10' or 6'x12' work area and the machine is far less expensive than comparable 4'x8' laser systems. We are also developing a 4'x8' 80 watt system where the tube is in the horizontal orientation. More information can be found in the R&D section.

I am interested in getting your 40W laser system. How difficult will it be to increase the size to 48" x 48"?

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?

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

The greenBull CNC machine kit can cut as thick as a material as you desire depending on the reach of the end mill that you provide the machine, if it is a straight vertical. The reason for this is that each pass is incremental (multiple passes at a certain depth per pass). For instance, if you need to cut a 2 inch thick piece of wood, you can make, say 3/4" passes until the target depth of 2 inches is met.

The depth per pass, feedrate and RPM will be determined by the material: wood, plastic, metal and will also be determined by the end mill that is used for that material. Selecting the appropriate end mill is very important. Feedrate and RPM is important to make sure the end mill is as cool as it can be during the cutting process.
