I am actually going to go for 3/8 thick if I can afford it. I am now upgrading to 3x2 box tube and 2 1/2 angle -all at 1/4" thick. As a point of reference, I made mine out of steel (1x2 box and 1 1/2 angle) and it is nowhere near as rigid as I need. Also, if you think it is strong/rigid enough, triple it. Read every forum and blog you can find and then read them all again. I am just starting the second version of my CNC and I can tell you that there are about 1000 things you have not thought of yet.
PC WITH PARALLEL PORT CNC PC
You need a full-size PC with a real parallel port.

PC WITH PARALLEL PORT CNC SOFTWARE
Depending on the software you choose to control it, the configurations may need to be inverted on certain inputs or outputs. Please note how they are designated inputs, outputs, or both. Here is a pinout of a DB25 parallel port:

This is not a problem for EMC or Mach3, but currently KCam will not allow you to use a non-standard parallel prot address.

The Windows XP drivers will not let you change the address. MOSCHIP NM9805 Chipset driven boards will initialize at non-standard addresses. We strongly recommend that you use an add-on parallel port card. The PBX-2 is not an isolated breakout board. The built in parallel port on your PC generally shows up at address 0x378, but that is determined by your BIOS The Parallel Port was primarily designed for controlling printer devices, so on some pins the logic inside of the PC is inverted for different reasons. Use the jumpers to ensure that both regulator sections are not connected at the same time. Some of our drivers also have on-board logic supply regulators.
PC WITH PARALLEL PORT CNC DRIVER
The IDC cables can supply logic side power to your driver boards. It probably would not protect you from spikes, so USE AT YOUR OWN RISK! I would recommend driving it through an externally powered USB hub. However, I have been using it for quite some time, on my PC. Your results may vary, and I assume no liability for your PC. It is very likely that your PC's USB port is protected from current overdrive. The USB specification allows the USB port to drawġ00mA, without needing to enumerate.

JP6 isolates the LM317 based regulator section from the rest of the circuit, including the logic power indicator LED. Do not plug in a USB cable without disconnecting JP6. This jack can supply the +5V logic supply side of your drivers. The PBX-2 has an experimental USB power supply jack. Any voltage between 6 and 40 volts should work. Make sure to test the polarity of the the wires from the WalWart, and make sure it is not an AC output device. You may want to run it off of a WalWart to provide an additional layer of protection and to limit noise. The LM317 is rated for 40VDC, so you can wire it up to the same power supply as the motors. The pullup resistors are needed in most cases when switching the logic inputs through physical switches. It also connects to the limit switch and e-stop inputs through a jumper connected 10K pull-up resistor network. The PBX-2 has a built in LM317 based voltage regulator section that will supply 1.5AMPS +5V to the driver outputs of this interface. It is compatible with a variety of Parallel Port CNC Control Software. The PBX-2 is a Parallel Port breakout board designed specifically for Hobby CNC machines.
