You will not have a problem cutting cured composites using any of our machines. The greenBull short Z has a very rigid gantry and Z-axis assembly and can cut with better performance.

You will need to make sure you are using the appropriate end mill for the materials within the composites. Additionally, the variables you will need to consider if the composites are thermoset or thermoplastic and the feedrate and depth per pass will need to be adjusted to make sure that the heat is is not built-up at the end mill causing the composite material to exhibit undesirable results.

Yes, you can absolutely communicate with the Pokeys57CNC controller. The developer's website has various ways of control, including their poblock software, or directly programming using C#, or C++. I have tested the C# method for a job I did for Lockheed Martin and worked really well.

[596] Hi there! Thank you for your great works. I was wondering if there is a way to communicate with this board using custom-developed software instead of Mach3 or Mach4.

The only plans we sell for any machine, are the ones that relate to the book we create found here, http://www.buildyourcnc.com/Book.aspx

Here is the link to those plans that we sell, http://www.buildyourcnc.com/cnckitintro.aspx

We do not sell any other plans, only full kits, with or without electronics.

I am wondering if you also supply plans for the bigger machines, also the vertical CNC that you have in your product range?

The files and hardware option for our machines has been removed from the site due to the following reasons:
Difficulty for the end use of the files and the challenges (and time/money) on our side to assist in using these files.
The abuse of these files over the internet.
Ultimately may reduce the sales of machines keeping us in business.
Sadly, this is what has come out of our company attempting to be open; however, the machines sold on this site is still far lower in price than the competition for the quality that we provide as we have a great desire to engender the cottage industry to fulfill their need for low end manufacturing. My sincere apologies if this causes any inconvenience.

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.

How thick can the Greenbull cut and what kind of material? Wood, plastic, steel? I was also wondering if there is one anywhere in Nevada, Idaho or Utah that I could possibly see in action. Thanks

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.

Currently our greenBull can only accommodate a 40W laser tube due to the size and current mounts on the spindle/laser hybrid assembly!

However please contact 281-815-7701 for further assistance with the greenBull machine.

I am interested in the GreenBull 4x8 CNC machine kit you have; I also wish to get the laser attachment but I was wondering if its possible to have the laser larger than a 40w, say in the 80-150w range?

Have you tried comparing all of the parameters for the motor outputs? For instance, go into the motor outputs screen in the mill profile, take note of all the parameters. Then open the turn profile, go into the motor outputs and change the parameters from the notes you had in the mill profile.

If that works, do the same for the other setting screens.

When you purchase the blackToe 2'x4' CNC machine kit, you determine the length. The 4' is only the suggested length unless you purchase the optional table. Just construct a table that is 8' long similar to what this customer did:

It's best to design a machine specifically for a lathe rather than adapting an existing machine kit to an existing lathe. If you are interested in us designing a machine like this, let us know.

I WOULD LIKE TO KNOW IF THERE IS A STORE OR SHOP WHERE CAN SEE THE PRODUCT AND BUY IT?

You can determine if the area is serviceable by:
- selecting the items you want to purchase on the website
- go to the cart (shopping cart top left of any webpage)
- log in, or register
- Enter the address and click on calculate shipping.

The webpage will return the direct rates and whether your area is serviced or not. Feel free to enter any address as long as you are able to receive the package from that address.

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.

the bluechik - IS there a 3D Touch Scanning to scan in present made items ?

Do you use the same bit?? If so, check if it is not dull or worn. Maybe it is time for a new bit. Additionally, I would check if the z axis mounts are tightened correctly and the router has no wiggle room. If that doesn't help, check all of the play that may be in the structure and where the bearings run along the rails and tighten all loose connections that may be present.

Additional Information:
So confused....is backlash and chatter the same thing or are they completely unrelated?

Additional Information:
Chatter and backlash are different. Backlash is a condition where there is play in the mechanical parts (i.e. a nut not tight against the treads, or two gears not meshing together tightly). Chatter is a phenomenon caused by many possible conditions including vibration, resonance, springiness and flexibility in the system and certain types of end kill and machine movement scenarios.

I recommend using a an output terminal to turn on and off the laser for safety. All you need to use is the M7 (or 8) to turn the laser on and M9 to turn it off. These M codes are use in conjunction with the output terminals to control external devices. The last Pokeys57CNC tutorial part explains this concept. You can use this idea with your controller.

How do you configure usb cnc and the mk1 board to toggle the laser? I use jscut.org to create gcode files and am wondering if I create a setting to disable the laser when it goes a certain distance above 0 on Z+.

The 12V power supply has 3 terminals for AC in: N, L and earth ground. The output of the 12V power supply has 2 DC + and - terminals. Cut the connectors off of the ends of the fan and pump wires. Strip the red and black wires of both units. The fan will connect to the 12V power supply red to the + and black to the -. The pump will connect in the same way, but the white is not connected.

If you have a pump that has a grey and black wire on the large connector, the grey is the 12VDC V+ wire and the black wire goes to the V-. The extra wire does not need to be connected.

They do have a similar looking thread as the G1/4”, but I will confirm in the morning. We use the G1/4” on the pump and radiator so it will be easy to determine this fit when I get into the office.
