Andy, Here is my HAL file. BTW, I looked at the PWM signal with a Tektronix scope, and I see nothing - constant 5V. Thanks for your help! ********************************************** # Generated by stepconf at Tue Mar 8 20:30:20 2011 # If you make changes to this file, they will be # overwritten when you run stepconf again loadrt trivkins loadrt [EMCMOT]EMCMOT base_period_nsec=[EMCMOT]BASE_PERIOD servo_period_nsec=[EMCMOT]SERVO_PERIOD traj_period_nsec=[EMCMOT]SERVO_PERIOD key=[EMCMOT]SHMEM_KEY num_joints=[TRAJ]AXES loadrt probe_parport loadrt hal_parport cfg=0x378 setp parport.0.reset-time 5000 loadrt stepgen step_type=0,0,0 loadrt pwmgen output_type=0
