Hi Tony,
Sorry to burst your bubble but I don't think they are suitable. The Geckos G320 are expecting a rotary encoder that must be directly and positively linked to the servo motor
shaft. What you have is a linear scale that is not absolutely and directly linked. I suspect that that flexure/backlash/lost motion between the axis (as measured by the
linear scale) and the servo motor shaft would render the G320 feedback loop unstable.

I revisited your responses from the beginning and I note that you mentioned the Gecko 320X. I just had a look at those and they appear to be suitable.
