General Mach Discussion / Nothing is moving...

« on: June 02, 2010, 05:33:50 AM »

hi,

I 'm newest in CNC and i have some problem : motors don't move

I am setting up a 3 Axis system and am using a package from Kelinginc.net which is

5056 drivers using a C10 breakout board.


On the C10 board, I have jumpers set as follows :

__Pins 2 - 9 jumpered for output

__Pins 2 - 9 jumpered for pull down

__com jumpered for com=5V

__input pins 10 - 15 jumpered for pull down

-Pin 2 = x step  -pin 3 = x dir
-pin 4 = y step  -pin 5 = y dir
-pin 6 = z step  -pin 7 = z dir


there are no limit/home switches connected.
there is an Estop switched to Pin 10



thanks for help...
