Getting up and running in Vista

Thank you for reply
Yes i do have a 5v pwer supply but is only operation is to put 5v to the micro stepping driver
the 5v that suppost make the stepper motor moving should come from the computer that what i been told by seller

The 5V to the driver may just be for an ENABLE.....not sure though.
A buffered breakout board accepts the 3V signals from the port, then provides stable 5V out to the other components with an extra 5V ps..
Your board may be opto isolated but NOT buffered.

Language to complicated for me once agai thank you for try to help it is very appriciate
now what do you mean with board may be opto isolated but NOT buffered
and also can you help me or tell me if there is a esear way to make the machine move?

You said in reply #50 that the 5v was going to the DRIVER...there should be 5v going to the BREAKOUT BOARD as in this picture. Do you have this ?
This will then provide 5v to the drivers..which should make the motors run.

edited for spelling

OK..I see.
I think that breakout board you have NEEDS 5v from the port.
Take a look at this one.. http://kelinginc.net/c10.pdf  ..and you will see that it accepts 3.3v from the port.
I think this is what you may need.
Others people might help here too.

Carmine,
  While you were on the phone with Keling, did they say the KL-DB25 board would accept 3.3v ?
Their website is poor, the only specifications on the board is a picture.
Could be other problems, but I would verify this first.

Thank you very much Russ please allowd me to 2 more question
1 in the drawing that you send me at frist woul i be able to jump 5v power from terminal 5v to EN terminal or i need a different source of power?
2i have 4 different jumper on my board you are tell me that moving one of the jumper will power bust the 3.7 volt and make 5v or allow the brak board to work with lees v?in the second drawing is different wiring schematics will wor also for my application?
thank you very much for the magnificent help

and in regard your last question keling keep repeting that the out put from the DB25 sholud be 4.7v to 5v
