### Question #: 561

Question: IS DRILL BIT USED IN THE CNC MACHINE?

Current Solution

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.)

• THE CNC MACHINE IS UNSAFE WITH EXPOSED SPROCKETS THAT CAN DAMAGE FINGERS AND HAVE CLOTHING CAUGHT IN IT.

These machines are inherently dangerous. Before the machine moves, the machine should be clear of any person by a dimension of at the distance of a persons reach plus a few more feet. This is the policies we institute in our shop and what is recommend to all of our customers. Treat these machines as you would treat any major power tool in the shop.

With that said, you can certainly add some protective parts, but still keep folks away even with those installed. I would use the gantry side to do all of the mounting of the protective parts. Consider using sheet metal that you can bend and make a simple installation right on the gantry side.

• Which electronics package is required for the CNC machine from the book designs?

The book design uses all NEMA 23/24 motors which can be found here:
https://buildyourcnc.com/item/electronicsAndMotors-3axis-425-elcombo

I recommend the Mach3 USB option as you will be able to use the USB connection for control.

If you are planning to build from the plans developed by the folks over at Woodsmith Magazine which is loosely based on the book design, use this electronics package:

• Can you repair the electronics on my CNC machine?

Yes, you can send your electronics to us for repair, or retrofit to work with either Mach3, Mach4 or LinuxCNC. You can send us an email at customerService@buildyourcnc.com to set up your appointment.

Some of the types of CNC electronics we will consider.

- We will work on electronics from other manufacturers as long as you are ok with the Mach3, Mach4 or LinuxCNC control software for your CNC machine or CNC router.

- We will repair or retrofit used CNC electronics.

- Some customers find that electronics are overwhelming to put together so we will finish these electronics wiring and assembly for you.

The cost for these includes labor cost for the time it takes to finish the CNC electronics repair or retrofit and for any parts that need to be replaced or added.

Here is an example of CNC electronics that we worked on for a customer:

This is the type of response that you can expect to receive after the CNC electronics are repaired or retrofitted to work under Mach3, Mach4 or LinuxCNC. You can see the entire work, which also shows the time involved. We also show what we were able to accomplish at the beginning of the video.

• can the greenBull Kit CNC machine cut HDPE Seaboard?

The greenBull can cut HDPE Seaboard, and other materials as well. The machine will be cutting with either a router/spindle(customer preference) and will be the greatest aspect of actual cutting of material, to get a good overall coverage of materials. Our 2.2kW spindle will be the best option for a large variety of materials.

• SHOULD I SELECT THE GREENBULL OR BLACKFOOT CNC MACHINE?

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)

• Can a CO2 CNC laser machine be used for welding of thermoplastic materials?

That is a good question. We have not tried to weld thermoplastics using our CO2 Lasers. It is possible since the laser outputs a heat source and at the right intensity and speed, the thermoplastic can be heated and melted rather than instantaneously vaporized and off gassed. I have done research to see if CO2 laser can weld thermoplastics with positive results.

Our CO2 lasers are typical of other laser cutters on the market, so if their literature, or examples you have found, successfully weld thermoplastics, then ours will probably be able to as well.

In some cutting test with different speeds and intensities, the kerf has welded back together; however, this was caused by an unintentional process rather than an intentional one.
