These were the typical messages, there was always 0 scan records, the "previous barrel" value always matched the "barrel" value, the actual values varied from about 1800-2100 in the CCW direction and 59000-64000 in the CW direction. So it does appear that the program is stopping the barrel when it sees values outside of the normal range which ends around 8000 in CCW direction and around 58000 in the CW dir. COMMENT: Thu Apr 17 20:18:39 GMT 2003 Extended the dome slot. Thu Apr 17 20:19:27 GMT 2003 MKIV Start Patrol **MKIV PROBLEM**: Thu Apr 17 20:38:58 GMT 2003 O-scope is connected upstairs to stepper motor board for barrel, the barrel is behaving so we'll have to wait for it to misbehave to analyze the signals further. When running correctly the pulses are about 17 ms apart for each of the 4 inputs that we can check.
