Thanks for your help Dennis,
But actually I am able to move the optics, just the stylus arm won’t move accordingly. At one point yesterday the stylus would not go up, then it somehow reset itself and worked for a few measurements and then it would simply not go down. It somehow feels like something in the electronics…

Hello Virginia,
With the optics stuck in the UP position, with the focus knob not allowing the user to lower the optics, is typically caused by the stylus sensor circuitry thinking the stylus is on a sample. The most likely issue is that the smoked plexiglass stylus "guard" at the front of the sensor has been pushed UP inadvertently by the optics being driven DOWN, raising the stylus arm UP from its resting position on the small pin in that guard. This happens when the optics are left in a high magnification position where the user can easily lower through the field of focus. You can loosen the Philips head screw attaching that guard to the front of the sensor nose and lower it slightly, then try lowering the optics knob down. If it still does not move, lower the guard a little more, making sure the stylus arm can "swing" within its arc ~ 1/8 inch. If the optics are still stuck in the up position, then its very likely that the sensor tower leadscrew is jammed at its stop within the sensor tower; this will require service by a qualified Veeco/Sloan Technology service engineer. You can contact me directly for additional help.

Dear all,
our lab still has a Dektak 3030ST profilometer and we are having issues
with the stylus. First it would go down and wouldn't go up, then I
managed to get it working for a few measurements and know we have the
opposite problem: the stylus won't go down.
Plus I moved the optics to see if the sytlus would go up (or down, now
that it is in an upper position), but the scan head doesn't move at all.
Does naybody have any idea what this could be due to?
Thanks
Virginia
