My attempt resulted in an extremely slow step generation, which I later found was likely due to me grabbing stepper_timer_count(not needed in my example, bad copy/paste) and not stepper_timer_current_count. So it was adding delays on delays. Will try tonight with a more proper test, and more time hopefully.\r\n\r\nCommenting out the rate limiting block did not have any affect on the extruder step generation."}}
