I just discovered this page: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PWM_Servo_Amplifiers
This should be a great help. I wrote a .ngc file with "g1f20x.4, x0,%" in it. I setup Halscope, the same as the above link, on one screen with EMC and EMC's Calibrator in another. I make a change in Calibrator, jump to Halscope and invoke single trigger then jump to EMC and run the program and finally, I jump back to Halscope to review the data. I am hoping to get some screen shots on my website. Is there a way to save the captured data to a file and then load the file to halscope for viewing later? Viewing the real data would be better than a screen shot. I was also thinking that it would be good to have EMC loop an axis move and have halscope update on the trigger, as it already does, and then be able to tweak the PID settings as EMC loops.
