@LightBurn I’m getting more valid results from the analyzer after changing the device settings to get consistent behavior. Please see if the settings look right though to double check.
The last three pics are the results of three tests. One test was a 50mm ø circle, and the pulses were 16000. Second test was a 75mm ø circle, and the pulses were 24000. Third test was a 100mm ø circle, and the pulses were 32000. Logically, this makes perfect sense.
To recap, the X and Y axes distance per pulse are set at 6.25 µM in the Trocen DSP. So, I’m not sure what math is necessary to determine if the total pulses are correct.
My math seems to work out to this for the 100mm ø circle results:
32000 pulses * 6.25 µM per pulse = 200000 total microns of movement.
Which equals 200mm.
Also, found that changing the Curve Tolerance setting in LightBurn had no affect on the amount of pulses recorded. I’m assuming that is correct behavior?
This will be a big sigh of relief if the DSP can be confirmed not the issue with your input.
All of the X and Y axes pulses matched (again, please check if I did something wrong). 
Much appreciated!
I also saved the pulse dump if you would like to take a look (requires free DSView software to open).
