Simon,
We had the same problem before. Our problem was solved by lowering
the Pal injection motor speed which is found in setup-objects hitting
the "hidden" F3 button a couple of times. For your reference, our
current setting for motor speed is as follows:
Motor Z:Down speed 200 mU/s
penetrate speed 10
Inj penetrat speed 10
Hope this helps.
