If you mean http://www.pastebin.ca/1583502 then that was me. The columns (which are messed up, but tab-delimited) show timestamp (once every servo thread),the measured spindle speed (encoder.0.velocity * 60), the encoder channels (Z then A) , the output of encoder.0.position-interpolated and then a column calculated in Excel which is the difference in position-interpolated sample-by-sample. I am not sure what it all means. Something I intend looking at tonight is what encoder.0.velocity does on an index reset (which is missing from that data) As an extra datapoint have a zoomed-in Halscope of my encoder positions at http://imagebin.ca/view/ud8Tect.html which I think shows that my printed-paper encoder isn't as obviously hopeless as has been assumed (including by me) -- atp ------------------------------------------------------------------------------ Come build with us!
