Sure, here's a more detail explanation.
I'm using my CNC with a 3D acceleration captor to test (accuracy, reproductibility, ...). So the CNC is the consign and the captor measurements the results. Then I can compare the results to the consign. The CNC is much more accurate in position than the 3D captor, so from pure static position viewpoint, it sounds safe. However, when we try to analyze the dynamic behavior of this system, it's less obvious.
That's why I'm expecting to collect the path of the CNC head in a log file. My best wish would be to get the (time, X, Y, Z).
-> How?
(Then if possible), can I trust these logged coordinates, at which accuracy? For example, a lag from the real head position compared to the computer real time expected value? Can I quantify it?
I wish it is more clear, no?
