cnc mill some suggestions

Sawmiller

hi all,
been a while since i have posted.. been making and playing with cnc routers.
i thought i would pass along a few links and suggestions for anyone looking to make thier own, and doesnt want to use a computer for the controller..
it seems to me that from the hardware standpoint , if you took a 4 axis controller board from here.. $8 http://pminmo.com/PMinMOwiki/index.php5?title=DIY4axisinterface·and used sip's ·instead of a db25 connector, you could mount the protoboard as a daughter board to it, add a SD interface to the protoboard.
use the A3977 motor controller boards from here www.pminmo.com
and make your chassis using the technics shown here www.buildyourcnc.com
it would be pretty simple. i've made 2 machines using phils controllers, they work good. i'm using a computer with mach3 to control them right now, but later i might adapt one of his 4 axis boards as described and write a gcode interpeter so i can sneakernet a gcode program on a sd . especially if i find myself making the same thing repeatedly.
this would be sorta like zed's idea, but if you set it up for gcode, then you can use stuff like eagles pcb output and other free computer gcode generators... no handcoding
just a thought.

A topic that I find quite facinating - except for the fact that I can't access the buildyourcnc web site. Microsoft Internet Exlorer V6 goes into a 100% processing loop for me - pity about that. The other link was interesting.
