My system is comprised of 3 different setups, one vertical, one horizontal and one which can configured as both vertical or horizontal. I’m using THK KR20 and a KR26 equivalent linear rails with 400 step motors (NEMA 17) for driving the camera/lens (Nikon D850 or D800E or D500) with custom lens configurations. I use 2 THK KR15 linear rails with 200 step motors (NEMA 11) to move the subject (silicon chips we design). A Raspberry Pi 3B + was selected as the main control computer and Tic-500 as the motor controller/drivers. You can see some of the setups below, including the Tic-500s. Note that I (mawyatt) mention the Tic-500 often, and very favorably!!

Here’s a link that shows an early test image of a silicon sliver from a broken silicon wafer. Be sure to download the last image " Another S&S Test Image of Old Silicon Wafer Sliver" to see the full resolution
I have images much better than these simple test images, but they are proprietary.
Best,
Mike
