Would it be
any difference if you run the machine at full speed or lower speed...
Ah, yes -- this I haven't tried yet! I have a KM11 replica, so this is easy enough
to do; I'll give that a go when I next get back to the machine (possibly this
evening).
Ran the machine on the maintenance clock via the KM11 at a variety of speeds, and the
behavior remains the same. So not too timing sensitive... At least its consistent!
