Good work and glad you made the better half happy.

Last kiss I got at night turned me into a frog. So watch out my friend.........

Mach4 General Discussion / Re: New people welcome !! Come in here and introduce your self!

If you can run other machines then it's a matter of the controller interface and of course some differences in the gcode.
Maybe just download and install Mach on your PC and have a look. They may use a custom screen set and as such it may resemble what your accustomed to.

Another option would be to watch some of the available videos.

That said, I would not worry about it.

Since your in a production mode i would suggest that you first define how fast the drilling per piece must be.
Then based on the most efficient code for the work, evaluate the required machine to do the work.
That will quide you on what you need.

Russ,
USB modem ( the one from US Cellular) > amplifier > Mofi Router > connect wireless or by cable to any computer.

>.....means connects to

You need to have an adequate signal from US Cellular, the amplifier can improve that,once you have a strong signal the wireless router
can be used to connect to any pc / or pc's via CAT 5 cable or wireless.

Test that can be done:
 Mount the USB modem up on the pole / out the window on upper floor  and run a usb cable ( can buy a 15' for about $11) from the usb modem to the laptop. The usb cable is limited to about 15 feet but if it works may be able to eliminate an amplifier. The cable length can limit the data transmition rate from the router to the PC.  Certainly worth a try.

Hey Russ,
Send me a PM with your telephone number ( not sure if i still have it ) and I'll give you call tonight / you pick the time.
At work got to go......

I would expect that there will be a complete new manual available which fully describes functionality and use  of the different versions of the 4 release.

Russ,
Correct.The MODEM recieves the providers signals. Sorry about my description. And since you are using an exsting old phone line
system and not cable then the rate of transmission over the phone line is painfully slow. Talk to your provider since you want a modem that
will be using an external antenna instead of a land line.  They will know what can or can't be provided and what you can expect. If you lease it from them, then if the result is unsatisfactory,you can return it. Additioinaly  the technician can set the modem up for you plus you are using their provided software.

The modem is connected to the router via a cable. The router is also wireless and has a small antenna which transmits to the USB device at the computer or you may have a newer computer with one built in. ( similar to  using a wireless mouse). The connect range to the router is usualy lower than an external one. Netgear sells wireless routers for example and may come with a USB device. The router is set up such that only your computers can tie into the router. Range could be up to say 150 feet. You also use software provided with the router.

. From your description, I'm seeing a wireless router, with an EXTERNAL outdoor remotely mounted receiving antenna via cable on a pole that is compatible with the providers system. This would negate the use of their modem ? Or, where would their modem be used in your example.

See above.

Russ,
The router sends and recieves signals.  So it acts as a transciever which is a radio which can transmit and also recieve signals.
The router is designed to operate best in a range of frequencies. The antenna is also deisgned for the same range of frequencies
and can enhance both an incoming signal and outgoing signal and that is expressed in terms of its gain. 3db doubles or reduces
the signal power. By "deisgned for", the antenna can take those electrical signals  in a certain range of frequencies and enhance them and same goes for the router. The router has internal circuitry to accept and reject  signals not in its range of frequencies
so it filters outs the signals.

So if you point the antenna at the cell tower you'll get the best transmissioin and recieve to and from the routers antenna.
Just like what you do for an old TV that uses an antenna. Comunication towers can have a beam width angle of only 1 degree.
Thus antennas have transmit recieve and gain, more sensitivity to certain signals, and can be more directional and that depends the type of antenna.

The signal from the router has a very low power level, mw ( milli watts ). The line connecting the router to the antenna
will cause signal loss. Since you don't have much power you want to minimise that loss and as such you want to use an
appropriate cable for the range of frequencies it will transmit. The antenna will then increase that signal to the cell tower.

The less abstruction in the path of the signal the better the electrical wave can travel. So mount the antenna on your pole
above ground with the cable from the antenna to the router inside. The PC wireless USB adapter can then be used by any computer to communicate with the router. Another way is to run cable to the router from the pc.

Tried to keep this very generic and not get techie about anything.

Hope this helps,
BTW, Merry Christmas

Russ,
I use a wireless USB modem on the pc in the basement and the router is 2 floors up  and have no problems.
The modem is rather restricted in how far it can send a signal. Rather limited in power and some of them have better range than others. Now the router is rather limited in it's reception also.

You can increase the range of some of the modems by making a very simple more directional attenna.
Since it's rather line of sight you may be able to point it in the right direction and having it off the ground will help avoid line of sight abstructions.

How far / long can the line be?..........well it depends on the signal loss thru the wire and the power gain of the attenna.
Can be tweaked and measured but doubt you have the stuff to analyze. Know any ham operators in your neck of the woods
as they could probably help you out.

I need to ask my friend and get a lnk to the how to do it.

No cost just some Al wrap and cardboard. It'll be a few days before I post the info.
