It sounds like you need to add a "stage" to help position your sample. Flexures are systems that bend to perform motion, and can do surprising things that you can't do with joined together machined pieces.

Here's an open source stage project using flexures that will likely help

Also, see Dan Gelbart's 18 video series about building prototypes

I'm a fan of this project, but flexures are antithetical to an STM assembly. And STM needs very rigid components, the smallest vibration can interact with the height adjustment and push the tip into the sample.

But it's a great assembly for anything that doesn't have a feedback on the positioning.
