Curve not linear with cheapo laser. Although I have fits that should convert from mW to control values based on sensor valuyes, These are failing near zero. I ask for 0 mW but still get quite a bit of power. I therefore for now hard-code an if statement to set power to zero if user asks for this 9d85c53fc7a95ae88ccc8daa0022364ab8989175
I think the fits should be constrained to go through zero. Maybe I need to re-do the fit with the control values re-scaled according to the max/min of a power meter. Then run one conversion instead of the two conversion weirdness I now do.
We are close, though, regarding the commands themselves.
