Scientifica Patchstar
I’ve been playing with a Scientifica Patchstar. The Patchstar is a patchclamp manipulator. It has a claimed electronic resolution of 20nm which is pretty impressive but I think that’s just the step size.
Unfortunately I don’t have the driver, and a new one would cost about 1500USD. However it appears to just use bipolar steppers and operates with an Arduino and a Easydriver quite easily. From the travel I get from the EasyDriver it looks like it would need to use 256 microstepping. I’ve purchased some drivers to try this out at some point.
