Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

The spindle is quieter and has more consistent torque (It doesn't get "bogged down" when it starts cutting into material). It can be used with collets of varying sizes (not restricted to imperial sizes). It is water cooled and so it does not blow air downward to cool the spindle like the router does. The spindle is also machined with much higher precision than typical routers and will have a much longer life.

No you cannot sketch any kind of metal unless its coated from the molecular level or having it coated individually. However there are some types of coatings (Thermark and Cermark) that you can use to coat the steel so that you will be able to use our laser machine to sketch any metal.

Registration is recommended for a number of reasons. Many choose to register their works because they wish to have the facts of their copyright on the public record and have a certificate of registration. Registered works may be eligible for statutory damages and attorney's fees in successful litigation. Finally, if registration occurs within 5 years of publication, it is considered prima facie evidence in a court of law.

check your in-going power and make sure that you have a good neutral connection. Frequently the issue is not the power supply but the power coming into the power supply that causes the problem. There is a chance that the power is good coming in but there is a loose neutral connection and that causes it. This is the neutral connection that runs all the way back to the panel in your home.

If you purchased a blackTooth that contains a motherboard and internal computer peripherals, and was also provided with a parallel breakout board, then you should have received a motherboard that provides parallel functionality. In fact, all of our motherboards have parallel port capabilities; however, the motherboards have the parallel port as a LPT header on the actual motherboard (not as a typical parallel port that would be located with the other external connectors. The header is labeled LPT and is generally located along the edge. The box that the motherboard is stored in shipping should contain a parallel port ribbon cable that connects to the LPT header on the motherboard.

I use a standard large "L" square used in construction. I run gantry up and down with the bit along one side of the square to make the square aligned with the x-axis. I then run the bit along the other edge and if I see space from the edge of the bit to the square, I adjust the gantry square by loosening and tightening the eye bolts that hold the chain at the ends of the table. Repeat as necessary to get the desired square.

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.

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.

The ports and pins are designated by the breakout board that you have, Now here are the schematics for both(https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/ and https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/) Which for the Parallel the pins will be 1,14,2,3,4,5,6,7,8,9. For 1,14 you will need to use them together for a additional axis. Setup will be (ex.mach3) step in (2) / direction pin (3). continued for other pins, 4,5 6,7 etc.
Now for the USB it has the label on the board right next to the terminal blocks, x-axis/etc.

1) Make sure to setup Primary partition:

Primary
Beginning of this space
Ext4
Mount point: /
and Swap partition:

Logical
Beginning of this space
Swap area using "Something Else"

2) get and install updates and upgrades

sudo apt-get update
sudo apt-get upgrade

3) get raid software

sudo apt-get update
sudo apt-get install mdadm

4) setup RAID

a) if raids haven't been setup:
sudo mdadm --create /dev/md0 --chunk=256 --level=0 --raid-devices=2 /dev/sda /dev/sdb

b) if raids are setup, but just have to be reassembled:
sudo mdadm --assemble /dev/md0 /dev/sda /dev/sdb

or

mdadm --assemble --scan
