A CNC machine is basically a computer controlled high precision tool that is able to make intricate movements accurately and repeatedly. Our machines use common routers and spindles to mill, cut, engrave and shape materials in automated machining operations.

WHAT IS CNC MACHINE?

There is virtually no limit to what a CNC can do. CNC machines are responsible for almost all modern day machining operations in manufacturing industries. They normally costs tens of thousands of dollars, or hundreds of thousands of dollars. Our machines can be used to engrave plaques, cut wood for kits, mill aluminum parts, and inject plastic components. All it requires is willing to learn and understand how to use the machines to accomplish what you want to do.

The Linux CNC (EMC2) does not require a high performing computer. This application will run fine on a Pentium or later computer system. You will need a parallel port as either part of the motherboard, or as an adapter that plugs into one of the motherboard PCI slots.

The blackfoot requires a total of 50 feet of cable.

The X axis needs 15 feet
The Y axis needs 17 feet
and the Z-axis needs 18 feet

These are 20 gauge 4 conductor cable.

Kerf is the cutting width from the lasers beam. This will change in width depending on your power level, higher power will increase your kerf width. This is usually around 0.15mm for a 40w laser using a 2" lens

You can determine if the country 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.

The shipping times are determined by the service you select in the shopping cart. If a machine is purchased, we generally have a one week lead time unless otherwise stated in the description of the machine's product page.

Hi - what is the cost of shipping the lean to CNC to the UK (8'x4')

Backlash is a term used to describe the looseness in a mechanical system. Backlash can occur anywhere in a machine, but is generally emphasized at the nut and lead screw connection. If the nut threading doesn't perfectly match the lead screw thread, there will be a wiggle, or play between both the screw and nut. This is backlash. Backlash can also be located in the motor bearings, coupling (connecting a shaft or lead screw to the motor shaft), collars not being hard against the bearing, or temperature change that causes various materials to expand or contract, making the connections loosened.

For our greenLean CNC vertical machine, was built and controlled using 2 651-oz in motors/425 oz-in motor.
The 651-oz motors runs both the x/y axis, as our 425-oz motor controls the z axis.

The lens is 20mm wide and a 50.6mm focal length (the one included). This lens will stand up to at least 30PSI air assist.

The mirrors are 25mm wide mirrors.

Focal length is the distance from the lens to the material for the laser converge into the best focal point. If a lens is listed as 2". You measure 2" from the lens to the material, this will be the tightest point the laser can go before it starts to re-expand again losing focus.
