Here is the wiring diagram for the MAch3 USB breakout board:

You will need 24 volt relays for the output on that board since that side of the board requires 24 volt power at the V+ and V-

Customer Response:
My inquiry is for the Planet CNC USB and 5v relays.
I am 99% finished with my 2 axis lathe build and this is the last item for me to conquer.
I want to control power to router, and vacuum with the BOB going through the 5V relays purchased on this site.
Thanks again.

Using the Mist, spindle or flood pins...

Buildyourcnc response:
There is an IN, GND and 5V for the digital side to engage the relay. There is an S, O and P for the power line of the device to be controlled.

The 5V and GND must be connected to the 5V and GND from the USB board. The IN is the wire from the output terminal (i.e. mist, flood, spindle).

For the power side, here are the scenarios:
- P to O connection is normally open
- P to S connection is normally closed

So, if you have the power wire that would plug into the wall, the L "black" wire from the power cord will pass through this part of the circuit (cutting the wire and one end in the P terminal and the other end in the O or S terminal). Generally, the P to O is used as this connection is normally open and when the relay is engaged, the circuit will close allowing the current to flow through that wire.

To loosen and tighten the collet nut for the 2.2kW spindle, I use a 22mm wrench (spanner) for the shaft and a 30mm wrench for the nut.

Temperature probe monitor. Very valuable. This keeps you up to date on your coolant temperature levels.

Voltage meter. This will tell you the exact level of voltage/power you are running telling the laser to run at instead of an arbitrary mark on a drawn wheel around your POT.

Ammeter sensitive to 1mA. This will be sure your not over driving your tube and reducing it's life significantly.

Hour meter. This will tell you exactly how long your system has been 'on' giving you a more accurate bead on the length of your tubes life.

Exhaust fan upgrade. The current fan included is 100CFM. You can buy 120mm fans that push 250CFM and I have included a guide on how to go about doing this here. http://buildyourtools.com/phpBB3/viewto ... 8cdd1802bf

To push the exhaust fan even further, if you have the room/power, I would highly recommend investing in a 600+ CFM "Dust Collector" system. 250CFM is still not suffice to draw all the smoke that can come off of 3mm or 1/8 MDF cutting job.

A cutting surface. I bought myself a aluminum 'egg crate' mesh from my local HVAC company. They are used a cover for fluorescent lights and work great for low impact cutting surface. They come in 4'x8' sheets and are easily cut to fit. The other side is if you can find a steel honeycomb cutting bed to fit. These can be quite costly or fairly affordable depending where you are looking. The benefit of a steel honeycomb is you can use high power magnets to hold material down.

HOW CAN YOU ENHANCE THE BLACKTOOTH LASER CUTTER?

An end mill smaller than 1.5mm or 1/6" is too small a diameter for end mills to cut through materials that are thick. A good rule of thumb is if the end mill has a cutting length that is more than what you want to cut, that diameter will be acceptable.

WHAT LEAD TIME CAN EXPECT FOR THE BLACKTOE MACHINE?

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 CAN THE ROUTER BE CONTROLLED BY COMPUTER?

If you use the 2.2kW spindle, it can cut at 3/4 inch or 19 mm deep with at least a 1/4" cutting diameter single flute end mill. You will get better results with larger diameter end mills, but that is the worst case scenario. I still recommend doing a finishing pass on the edge to make sure everything is perfect.

I haven't delved into using encoders with stepping motors too much. From my research, you need to have a controller that can provide the closed loop control, rather than software handling that process. I have also found from my research that using encoders on stepping motors is generally used to stop the machine in the case that the motor failed to achieve the commanded position for some reason and gives the user the chance to correct and continue with the job.

If you want proper closed loop control, it may be best to go with servos and servo controller that provide the closed loop control within the real of those two components.

There are several CAD/CAM programs out there for MacOS. Here is a list of a few: http://www.macuser.de/forum/f53/3d-2d-cad-395058/#post4499316
I've also read good things about punchCAD: http://www.punchcad.com/
Of course, there is always SketchUp if you are in a pinch. There are a few CAM plugins for SketchUp as well, but I've never used them, so I can't vouch for them.

CAD/CAM will get you as far as designing your parts and producing the g-code, but if you also want to run the CNC machine with your Mac, you will need a piece of software similar to Mach3 or EMC to run the g-code. I haven't been able to find anything like these programs that runs on Mac, so you may have to run Mach3 or EMC in Windows using Boot Camp or a virtual machine such as VMware or Parallels.

Personally, I would use the Mac to do all the CAD/CAM, then use a cheap PC to run the CNC machine.

Hi guys I’m new to the cnc and I’m beginning to learn how to operate and cad-cam software also my cnc runs on Mach3 my questions is if I should use MacBook to do all designs if I can have all this software to run on Mac or I have to use windows software to operate it? I have separate small computer connected to the cnc table who have Mach3 on it please help. Also if you know any other software much easy for beginners please let me know thank you guys!

Upgrade your mirrors to SI coated mirrors, using a HQ ZnSe lens and even pushing up to a beam expander will all boost power. The ideal order of experimenation for lowest cost would be changing out for a higher quality lens labeled HQ ZnSE lens. Next would be SI mirrors, which will absorb less heat and reflect better, the last would be to use a beam expander which expands the beam, reducing the heat signature on the mirrors and makes a tighter focal width.
