But the system I am looking to control is a stepper-based setup, and I'm not certain if the reference to SERVO_PERIOD is directly related to a servo drive, or if it is just a concept that applies to both servo and stepper based systems. SERVO_PERIOD is just a tag, it could be ELEPHANT_PERIOD Traditionally there was a base_thread and servo_thread The base_thread ran as fast as the machine was capable of and was used for things like software step generation which were time critical. The servo_thread was used for components that whilst they needed to be polled regularly, were not so time critical. The servo_thread at some point probably got the name because it was fast enough to run servos Machinekit has dropped software step generation and its reliance upon rtai kernels to get a low a latency as possible to make it work. The recommended stepper generation methods are FPGA card or SOC,  or the BBB PRU Therefore there is generally only a servo_thread, but if the INI file referred to ELEPHANT_PERIOD = 1000000 that would function just as well :) -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
