DOWNLOADING G540B.XML:

This is what I recommend:

$249 G540
http://kelinginc.net/ or http://retromationinc.com/retromation_015.htm
Keling will match this price with any other purchase.
$147 3 $49 KL23H2100-35-4B 381 oz motors for X, Y & Z
$060 One KL-350-48 48V/7.3A power supply. Because the G540 has an internal 7A fuse, this is ALL the PSU that you will need for four 3.5A motors--Anything with more Amps is simply wasted.
$010 Estop switch
$007 3 Home switches
$009 Straight thru parallel computer cable.
-----
$482 Total electronics cost.
 
$149 Mach3 License cost at Keling with above purchase.
 
$631 To spend at  http://kelinginc.net/
 
This most likely will be the best electronics for your router.

For LARGE routers:

$249 (1) G540 unkillable 4 axis drive. This IS a deluxe, advanced features breakout board also--COMES WITH 4th axis drive
and spindle-speed controller already installed.
$297 (3) Keling KL34H295-43-8A 906 oz N34 motors (Detunes to 520 oz W/G540.)
$060 (1) Keling KL-350-48 48V/7.3A PSU. (This will handle 3 motors & 4th axis/slave also.
$656

You won't need any db9 motor connectors with the G540, as they come WITH it. The G540 also has circuitry for simple spindle speed control and outputs for dc relays to turn coolant pump (Or router motor) on or off.

These inexpensive 48V relays are very good for starting and stopping spindle motor, cooling pump, vacuum etc.:

Unless you have the new G540EZ (Which adjusts current limit with trim pots) you will need one of THESE 1/4 Watt 3.48K resistors for each 381 or 387:

3.48KXBK-ND
http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en&site=US&WT.z_homepage_link=hp_go_button&KeyWords=3.48KXBK-ND&x=15&y=19

They only come in a pack of five, so about $1 for 10. With shipping it's about $3.50

While you are ordering from Digikey, might as well also get some spare F2318-ND G540 fuses:
http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en&site=US&WT.z_homepage_link=hp_go_button&KeyWords=f2318-nd&x=21&y=24

Or, in Canada:

You will also need an estop switch, Home/limit switches and a 6 foot "straight thru parallel port cable. These are all available from Keling:

http://kelinginc.net/CNCPackage.html

The G540 is so small that many are mounting theirs INSIDE the computer case.

Camtronics has a case MADE for the G540:

Keling sells a controller box with G540 already installed:
