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...

Just a thought but have you tied the 'Enable' pin to +5 Volts [X8 on the C10]  (if you haven't then all output pins will be at ground potential).

In an attempt to narrow down the problem and decide if it is software or hardware related.

Download and run Parmon http://www.geekhideout.com/parmon.shtml this will establish that Mach is configured correctly and that you can in fact write to and read from your parallel port.

I had yet downloaded parmon and all seems fine and when i try jogging motor pins change color from green to red and from red to green but there is something unusual when i used a multimiter to know parallele port voltage and it show :
pin 2 and pin 3 = 4.39v when i jog X+ and  1.86 with X-
pin 4 and pin 5 = 2.89v when i jog Y+ and  0.75 with Y-
pin 6 and pin 7 = 1.60v when i jog Z+ and  0.60 with Z-

pin 3 and pin 10 =4.40v
pin 5 and pin 10 =4.40v
pin 7 and pin 10 =4.40v

is that seems normal..!

Try changing input pin jumpers (on C10) to 'pull up' and configure Mach motor outputs to 'active low'.

sorry for delay...
 hi,
tweakie i resolved the problem:
 - first i bought i new pci printer card and it carrie  5v or 0v i jogging
 - second some integrated circuit "SN74LS00" was broken so i changed and the motor finally move...

thanks for help and suggestion
