Hi i am interested in the greenBull 6x with Hybrid Laser/Spindle Head (includes Spindle/VFD and Laser Components) - USB Interface (Long Z). I was wondering how much it would cost to get this machine to NZ?

CamBam specifically creates the g-code (machining operations) instructions to be loaded into Mach3. Make sure in your CamBam g-code file parameters, you are using the Mach3 post processor. If you have already done this, let me know. If you are not sure how to do this, let me know.

The cutting area is 20" x 40" for the book machine. This area is determined by the 2'x4' sheets that make up the bed of the machine. You can increase this area if you use larger sheets and adjust the gantry width by the same difference of the width of the sheets.

You can also use the plans from Woodsmith magazine to build a larger machine.

I am building the 24" x 48" machine from the original book and i was wondering if anyone can provide me with the actual cutting area possible with that machine.

I would first check the mechanical parts to ensure smooth motion. Is your machine bogging down during cutting or jogging/rapids?

You can increase the voltage to gain a higher speed for rapids/jogging, but make sure the driver can handle this voltage. There should be a max voltage on the driver label.

If the bogging down is happening during cutting, either reduce the cutting depth or switch out the drive and motor for the axis that is giving the problem.

[129] I have a Blackfoot and have a question about the power supply. I currently have a 36V power supply and my machine bogs down, would a 70V or something like that help, or will that blow up my machine? thank you!

The E.Lu.5 Error code on your VFD is related to Low Voltage.

The recommended action is:
- 1. Check whether the input voltage is normal. (the voltage from the wall/breaker to the VFD)
- 2. Check whether there is a sudden change in load.
- 3. Check whether there is any phase missing.

Unfortunately, these three recommended actions will probable require an electrician to test the line going into the VFD.

Hi, I live in Australia and am looking at purchasing the Blacktooth laser cutter and engraver. I am wondering what the cost to ship to Australia would be?

The space allotted for the laser tube on the blackTooth would not allow for a higher power laser tube. As the wattage of the laser tube increased, so does the length of the tube.

We do have a larger and more powerful laser in design and should be available in the second quarter of 2015.

Click the link to add information to this solution:
Can you install a more powerful laser/tube for us if we pick the $2100 option to have you build it? It would be assumed that there would be a new price for the machine which would reflect the cost increase for the new laser. Please say yes, I know you can physically do it. I have faith in you

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.

Click the link to add information to this solution:
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.

You can do raster and vector engraving on the greenBull laser/spindle combination. The methods of this process is not accomplished in the same way as the typical laser machines where CorelDRAW is used. The Mach3 laser plug-in can be used for the raster engraving and standard CNC g-code can be used for vector cutting and engraving.

The raster method will not be fast on the greenBull since the z-axis is heavy and there are inertial limitation on doing fast raster back and forth movement. Vector is the best use of this machine.

I am looking at purchasing the greenbull 5X system with the laser/spindle combination. Can the laser do both rastered engraving as well as vectored cutting with the same breakout board and software? If I have this wrong please let me know what would be needed to accompish this.

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 live in North Houston by Lake Conroe, Anyone around here have a 4x8 or larger machine that would not mind doing some simple cutting for me for a project?

Exhausting the blackTooth laser cutter is a very important consideration and should be taken seriously, especially if you are cutting materials that give off toxic fumes when the material is burned. You will want a 4 inch hose to connect from the blackTooth to a blower, and another 4 inch hose to connect from the blower to the outside. The blower should be sufficient to provide completely negative pressure within the laser enclosure so there will be no escape of gasses.

The connections at the machine, at the blower and at the location the hose exhausts outside should be thoroughly checked for leaks. Use a gasket, or silicone. Once complete, try cutting a non-toxic material that will give off an odor (wood, or non-toxic plastic) and try the system and determine if the smell is present.

We do sell the parts to convert your CNC milling machine to a laser, but you will need to develop the mounts that will hold all of the laser parts to the machine, if the machine was design and built by you.

We can offer guidance for this conversion.

I already built a 4 x 8ft carving machine, I would like to modify for laser cutting wood. Do you sell a conversion kit? I use Mach3 software and steppers. Thanks Ray

All of our CNC machines can carve at that depth without a problem and do 3d carving. Our typical application is cutting sheet materials, but a good percentage of our customers cut 3D bas reliefs or even more complex 3D objects using reference points and jigs.

Most of our CNC machines have a Z travel of at least 6 inches for the smaller machines and 7 to 10 inches for our larger machines. The Fabricator Pro has a Z travel of 10 inches.

Depending on your application, you will need to consider the length of the end mill (more than the deepest depth of the 3D carving) and the stock that you will be using. If the stock plus the length of the end mill exceed the clearance with the Z axis raised to the top extent, then you will need to consider the way the table/bed of the machine is formed (maybe with a depression to take advantage of the greater need for clearance).

The greenBull has the capability of Z axis travel of up to 36 inches, but I would recommend, if milling wood, that the Z-axis not extend more than 12 inches to reduce deflection.

Additional Information:
Most of the CAM software on the market will have 3D profile machining operation capabilities. CAMBAM has a very nice 3D prpfiling feature. The Vectric line of software can definitely handle this as well.
