Part List: What, Where, How much?
The basic millng machine without motors, controller or spindle is $350.  The current estimated total part cost for building the Lobo CNC mill with spindle router, servo motors and controller is: $878.  (The basic machine can also be used with lower-cost stepper motors and controllers.)  All of the parts needed, along with suggested vendors, are sorted into the following categories:
Prefabricated Sheet Metal Parts (precision laser cut and CNC folded)                         
Sheet metal parts are fabricated by a high quality sheet metal manufacturer, and can be purchased through Jeff Kerr.  Alternately, you can use the drawings (DXF version: lobocnc_dxf.zip or PDF version: lobocnc_pdf.zip) to get your own parts fabricated..

Motor Controller and Motors                                                                                        
The Lobo CNC mill was designed to use a custom servo motor controller board which connects to your PC via USB.  This option requires no wiring.  (See the Motor Control page for details.)  Alternately, you can wire up your own conventional stepper based controller and most NEMA 17 stepper motors.  The stepper motor option will yield lower performance, and will not give you the DRO dispaly feature.  Note: the software we provide here is only compatible with our custom servo motor controller board.

Stepper Option
There are hundreds of different options for stepper drivers and NEMA 17 stepper motors.  They vary considerably in cost, performance and ease-of use.  There is no particular recommended vendor, but you can try places like steppersonline.com, hobbycnc.com, or automationtechnologiesinc.com .

Off-the-shelf Hardware                                                                                                
Jeff Kerr has purchased in bulk most of the hardware that is expensive in small quantities (bearings, couplings, etc.), or a nuisance to buy separately (lots of different screws) and offers it as a hardware kit.  Alternately, you can purchase all of these parts separately yourself.
