Quick question here. The HAL file has two time intervals I believe in nanoseconds? BASE_PERIOD = 24000 SERVO_PERIOD = 1000000
So BASE_PERIOD is about 41.67kHz and SERVO_PERIOD is 1kHz? I'm guessing the encoder edges are counted between BASE_PERIOD Ticks to determine spindle velocity? Is that correct? That the trajectory planner calculates a new velocity relative to the spindle every SERVO_PERIOD? In other words the step rate to say the Z axis for threading is changed (or left the same) every 1mS. Have I got that right? Just looking for an overall simple description.
