### Question #: 420

Question: MY MACHINE CUTTING THE WRONG SIZE PART

Current Solution

In Mach3, go to the Settings Tab, and select "Set Steps Per Unit". It will ask you how far to move the machine. Before you do this, make a mark on the table exactly where the end mill is resting. You can do this by lowering the end mill until it touches the material, then spinning it by hand to cut a small dimple in the material. Then, raise the end mill to clear the material, and assign a distance to move the machine. Once the machine moves and stops, measure the exact distance that it actually traveled with a tape measure, and enter this value into the dialog box that asks how far it moved. Mach3 will automatically adjust your steps per unit for that axis to be more accurate. Do this for all axes often to ensure you are cutting accurately. The longer distances you use calibrate, and the more precise you are with your measurements, the better.

• IF MY COMPUTER DOESN'T HAVE A PARALLEL PORT, HOW DO I RUN THE MACHINE?

If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for \$15-\$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

• IS DRILL BIT USED IN THE CNC MACHINE?

The cutting tool is an end mill (it looks like a drill bit). It is a cutting tool that can plunge and cut sideways. That item is not included and is a consumable. You will purchase these very frequently and will have geometry that is very specific to how you apply the cnc machine.

• WHAT IS THE DIFFERENCE IN A 2.5 AXIS MACHINE?

An axis is a direction of motion controlled by the CNC machine control. It can be linear (motion along a straight line) or circular (a rotary motion). The number of axes a machine has determines it's machining capabilities. A 2.5 axis machine really has three moving axes, but only two axes can move together (most machines sold today are full three axis machines). For machining centers, a three axis machine will have three linear axes. A four or five axis machine will have three linear axes as well as one or two rotary axes.

Note that 2.5 versus 3 axis has yet another context. 2.5 axis machining requires that the machine have three axes, but only two axes must be moving simultaneously at any one time. (Simple operations, like drilling and most milling, fall into this category). On the other hand 3-axis machining requires that all three axes be moving at the same time (More complex operations, like the machining of sculptured surfaces required in molds and airfoils, fall into this category.)

• WHICH MACHINE SHOULD I BUY, THE GREENBULL OR BLACKFOOT?

The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

Previous Solution:
The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)

• WHAT MATERIALS CAN THE GREENBULL MACHINE CUT? LASER ETCH?

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.
