I agree, the spindles are timed by a parameter.
I can't recall where exactly it's buried.
Our Multus arrived having the No1 chuck jaws aligned and pointing down(C0), which was nice as we mill between both clamped chucks a lot.
Our Macturn arrived with each chuck (C0) at some random position. We aligned them ourselves.
I'm starting to think there is some very basic communication problem at Okuma HQ.
And probably a basic ATC design flaw as well.
I know Okuma have stated (several years ago!)that using a cleaning routine(M341) as part of the tool change cycle is a fix.
Why the hell do people(customers) in Australia, Europe, North America etc have to find this information through peer groups like CNCZone!?
Why isn't this made clear and set up ready to use, if needed, by the distributor?
It only reduces the frequency of dropped or jammed tools anyway.
