Well, if the price is right, overkill is nice isn't it? :-) Still waiting on a price back from them. Also, 10ppm over 3m/120 inches is only about 0.0012"... not sure if that is how that spec actually works (parts per million of full scale?), still waiting on documentation.
It will be working most of the time in a temp/humidity controlled environment actually, 24-27 degC, 40-60% RH and I'll be doing my best to eliminate vibration if it becomes necessary.
I was just curious if anybody out there was fixing any kind of permanent laser distance measurement onto their CNC machines in conjunction with or in lieu of glass scales.
