IHA0L08 Slipping on Retraction?
Log Number: 4470181Logbook(s): Entry Makers: bschaumlBody:
Attempting to take y-plane match data and the harp zigs but doesn't zag. One can see from the most recent scan in figure 7 that the "potScaled" axis is miniscule. When the harp is zeroed after the scan the potentiometer readback returns to the expected value but the servo motor position readback reaches something like -300 or -400 mm before getting set to zero, presumably when the harp hits a limit switch. Compare the behavior of IHA0L03 (Fig. 8) to IHA0L08 (Fig. 9).
