What is the problem with the tool tip replacement? Is it just the problem of the tip wearing down and having to be constantly replaced and shaped? or is the problem more complex?<BR>
I toyed with the idea of a home-brew STM not that long ago. I built a piezo scanning head in a few hours and then became distracted by a more interesting project. I have thought about continuing the STM construction and had a few ideas about tool and scanning head refinements. <BR>
Maybe this thread is just the incentive I need to get the project off the shelf.<BR>
