But that is the point; if you do not have feedback, then you will never be able to ensure that you are anywhere on the programmed path. No matter what driver you use. If one axis is slowed down externally, then all others need to be adjusted too. The real problem is, if the slowing force is reduced, who is controlling the axis' (re-)acceleration? If the HW driver is (partly) autonomous, then your controlling SW will always lag behind and create a larger path deviation than if the SW has full control. I.e. reactionary vs. actionary control. -- Greetings Bertho (disclaimers are disclaimed) ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
