Mounting the extruder to the whiteAnt can be done a couple of ways. One is to take the 4 mounting holes located at the lower portion of the z-axis rail support and use long screws protruding out. Take a thinner material and drill the four holes matching the locations of the 4 screws and screw on nuts to hold it in place. The other option would be to use the metal bracket and fasten to the edge of the rail support.

The roller chain lengths for the greenBull 4x is:
- 13 feet for each side of the X axis (total of 26 feet), and
- 6 feet for the Y-axis

WHAT LENGTHS OF ROLLER CHAIN DO I USE FOR THE GREENBULL 4X CNC?

BYCNC Response:
The book build was intended to be 20 inches x 40 inches. Larger machines were designed after the book build was introduced so customers would have the option to go bigger than what the book offered. Check out our larger machines on the website as the machines sizes range from 1 foot x 3 feet all the way up to 6 feet x 12+ feet.

User Response:
I'm not wanting to spend $3,000+ on a machine, I want to build one that will do a 4x8 sheet of wood. Will the plans in the book scale up?

BYCNC Response:
It is possible to scale the book build up, but the rigidity of the gantry would be questionable at that span, even if the height of the gantry structure were to be increased. The gantry design would need to be modified to become a box shape rather than a flat configuration. The kits on the site were design for those wanting a larger machine.

Yes, you can use the Autodesk123D CNC Utility found here: http://www.123dapp.com/aboutcnc

This utility will work with any standard CNC machine. Our machines use standard electronics and you choose the software that controls the CNC machine.

BUILDING ONE OF YOUR GREENBULL 6X LONG AND 2.2 KILOWATT SPINDLE DOES NOT FIT. SEEMS LEAD SCREW YOU SENT WITH KIT IS SHORT 42" LOOKS LIKE IT NEEDS TO BE 5 OR 6 INCH LONGER. THIS CORRECT? WHAT THE NEEDED LENGTH FOR UNIT?

The blueChick would be the perfect machine to iso route PCB boards. The A4 size is 8.3x11.7 inches and the blueChick is 12x36 inches. It's a bit larger, but you would be able to route many more PCBs. I would also recommend getting the 1.5 kW or 2.2 kW spindle for the blueChick since you will want very low runout to make the isolation routes (kerf) between traces very thin.

The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

Actual table dimension: 4'x8' is 56.078"x 121.50" (the overhang in the illustrations should be 3/4" thick)
To determine the frame dimensions, first consider using the frame height shown of almost 3' (2.86'). The width of the frame should be 4" narrower than the dimension from rail edge to rail edge (6X rail to rail is 80.078"). This will provide a 2" overhang on both sides (4X frame width should be 56.078").
The length of the frame should be 4" shorter than the desired length of the rails to provide a 2" overhang on both ends. The travel length will be 20" shorter than the rail length due to the space occupied by the gantry sides.
Two long pieces of 3/4" material will need to be placed on top of the frame with the 2" overhang on the sides and the end. These long strips of material will receive the rails and the chain mounts on the ends.

I have just purchased a 4x8 Greenbull system second-hand. Are there any schematics for table dimensions and rail-mounting available so that I can build a table? (previous owner disassembled)

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.

We don't have cad models of the HIWIN blocks, but you can find the models on McMaster.com. They have can drawings and models for most of these types of parts.

do you have CAD available for the hiwin guide blocks you sell and the rail?

Thanks for the kind words. The kit is available for those that want the parts to assemble the case which comes with the computer parts. If you don't need the computer parts, let me know and I will offer the bare bones without the computer system.

Previous Solution:
I already have a DIY CNC machine with all my electronics but I have two cases the size of a mid tower PC and was looking to shrink the weight and footprint of all of them. I understand if you don't have plans available, I just really loved the design and compactness of your case.

Previous Solution:
The redLeaf and redSprout boxes are meant to provide enclosure to the systems that we assemble in-house for customers that prefer a complete plug and play system. We provide the kit of parts for the enclosure from overwhelming customer request. There are no plans available for the enclosure and the complexity of the parts needed to be fabricated is quite high where the task of cutting out all of the intricate parts by hand would be a larger investment in time and materials than the cost to purchase the kit.

Additional Information:
Just curious at what you would sell the box itself empty or the dimension files for the box for?
