Question: How to setup RAID on Ubuntu

Current Solution

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

  • HOW LONG FOR ME TO BUILD IT?

    The length of time it will take to build a CNC machine kit is not an easy answer. There may be a wide array of circumstances that limit a persons abilities to build the cnc machine kit in an efficient timeframe; however, if you have moderate dexterity and moderately mechanically inclined, you should have no problem building one of our machines within one weekend if the project has very little downtime.

  • HOW LONG DOES IT TAKE TO SHIP

    Unfortunately I am not able to give an estimate of shipping time. This is because there are multiple shipping options, Some of them cost more than others, but ensure the package arrives in a certain number of days. Others do not give a number of days, and many factors could change the length of shipping time, such as weather, or busy season. It would be best to choose an option you are comfortable with the price of, and then Google search the typical times it takes for that option to get to you, or call the shipping company and request that estimated time from them.

  • HOW CAN MOUNT THE EXTRUDER TO WHITEANT

    Mounting the extruder to the whiteAnt can be done a couple of ways. One is to take the 4 mounting holes located at the lower portion of the z-axis rail support and use long screws protruding out. Take a thinner material and drill the four holes matching the locations of the 4 screws and screw on nuts to hold it in place. The other option would be to use the metal bracket and fasten to the edge of the rail support.

  • HOW TO COOL THE BLACKTOOTH 40W LASER TUBE

    Cooling is not as tricky as you might think. There is 3 ways to approach this, only 2 really matter for a low scale 40w setup. First one is the cheapest and easiest. The higher the temp of water the worse your performance will be, from what I understand anything in the 30C range is about the most tolerable it gets. Lower is better. But not frozen...from what I've been told a very experienced cutter, he found 8C was the highest power he achieved.

    1. Use a 5 Gallon resovoir system which gives you a fairly large space of water to heat up before you need to tend to it. Add about a cup of anti-freeze to the mix of DISTILLED water. You don't want ANY minerals in the water that might build up in your system. The anti-freeze works to keep algae and other ickies from growing in your water.

    2. Use a smaller resovoir system (or even closed loop) and install 1 or more radiators found in CPU cooling systems with 120mm fans attached. This will continously cool your water system to ambient room temperatures, but with a tiny resovoir it will be difficult to add things like ice-packs to drop the temps if the ambient is quite hot.

    3. Using an industrial coolant system. Overkill and unless your cutting A LOT, this is a very expensive option to take. You can also explore the idea of Peltier cooling but it is extremely expensive electricity/BTU wise compared to an industrial cooler.

  • HOW TO CONTROL MY 2.2 KW SPINDLE VIA MACH3

    You can go to our instructions on for the breakout board here: http://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay to get the information on turning the spindle on and off from the computer and mach3. Alternatively, you can connect the computer using RS485 serial to the inverter and send control commands that way.

  • HOW THE ROUTER IS CONNECTED TO ELECTRONICS?

    The parallel breakout board has a relay that can turn the router on and off according to the control software in the computer. The router will turn on automatically prior to the machine moving (a time frame can be set so the router is up to speed). When the machine is finished and is not moving, the router automatically turns off. This is with the m3, m4, and m5 codes in the g-code.

    If you are interested in the USB breakout board, you will need to get an independent relay board.

  • HOW DO I WIRE FROM THE BREAKOUT BOARD TO DRIVER?

    CP+ to COM
    CP- to STEP
    CP+ to CW+ (small jumper wire)
    CW- to DIR

    Additional Information:
    If the driver does not have CP or CW labels, the CP is Step and the CW is Direction or DIR. If you connect the 5v to CP+ (or Step+) and CW+ (or DIR+) and the pin to CP- (or Step-) and another pin to CW- (or DIR-), then in software, the configuration for the step on that axis must be active low. Otherwise, if you connect the GND to CP- (or Step-) and CW- (or DIR-) and the pin to CP+ (or Step+) and another pin to CW+ (or DIR+), then in software, the configuration for the step on that axis must be active high.

    Additional Information:
    If you have a driver that is labeled pul, dir and ena: Pul+ is the Step+ and Pul- is the Step-. Pul is short for pulse. A pulse will create a step. Don't worry about the enable terminals.

    On the x-axis, pin #2 can go to pul- and pin #3 can go to dir-. The 5v will go to pul+ and dir+. The configuration for each axis for step will be active low and toggle active low for the dir on each axis to make it go in the direction desired.
