In the AO_Lineframe.vi, the source clock rate for the analog out is set to 14000. This is lower than the frequency at which the Y-mirror is actually updated ie. 24KHz (once every scan line). May not matter technically, but should be corrected anyway to avoid confusion. For instance, looking at this number we just assumed that the clock signal should be the line trigger from the resonant scanner that's running at 12Khz. And totally messed up image assembly in the rest of the code.
On a related note, the scan waveform should perhaps be modified to include a less brutal turn around for the Y-mirror. Currently, its forced to swing back from end to start position in ~40 microseconds which may not be good its health in the long run.
