Is this the board?: http://campbelldesigns.net/files/breakout-user-guide-1-8.pdf http://campbelldesigns.net/breakout-board.php The break-out-board seems to just pass the step/dir signals through an opto-isolator, so for the most part the driver will determine the timing. What stepper driver are you using?

I don't know if the L297 configuration has the proper pin-out. If it uses the standard_pinout.hal, http://cvs.linuxcnc.org/cvs/emc2/configs/stepper/standard_pinout.hal?rev=1.7;content-type=text%2Fplain some of the pins are like: # standard pinout config file for 3-axis steppers # using a parport for I/O # # first load the parport driver loadrt hal_parport cfg="0x0378" # # next connect the parport functions to threads # read inputs first addf parport.0.read base-thread 1 # write outputs last addf parport.0.write base-thread -1 # # finally connect physical pins to the signals net Xstep => parport.0.pin-03-out net Xdir => parport.0.pin-02-out net Ystep => parport.0.pin-05-out net Ydir => parport.0.pin-04-out net Zstep => parport.0.pin-07-out net Zdir => parport.0.pin-06-out ... and the Campbell BOB: J2 Pin 1 = Out1 Pin 2 = X step Pin 3 = Y step Pin 4 = Z step Pin 5 = A step Pin 6 = X direction ... We would need more information on what hardware and your current configuration files. Another thing that comes to mind, are drive enable or watchdog (charge pump) signals needed? --------------- Kirk http://www.wallacecompany.com/machine_shop/ ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
