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 machine can cut a very wide variety of materials ranging from foam to aluminum. We recommend the use of our 2.2kW spindle to allow the greatest flexibility. Aside from that, the most important thing is to use an appropriate end mill for the material you are cutting and to use appropriate speeds and feed rates.



BYCNC Response:
Our 40W laser can cut up to about 1/4" materials ranging from wood and acrylic down through lighter materials such as leather, fabric, foam, etc. Speed and final cut are greatly enhanced by an air assist upgrade. We also offer an 80W laser which has approximately twice the capabilities of the 40W.

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.

You most definitely should have received limit switches in your package. We will send you the missing limit switches.

But to directly answer your question; no, limit switches are not needed with CNC machines. You can set up soft limits to make sure the machine does not go out of bounds.

With that said, if the motors stall for some reason and the computer does not know the actual position of the gantry or the spindle, then the machine may actually go out of bounds and the machine may hit a physical limit. With or without limit switches, the machine will stop.

Additional Information:
Please call the office so that we know who you are and we can send the limit switches to the correct person.
