---++ Swapped Driver Boards on 2/24/2015 * Charlie and Peter installed Driver Board (SN 02) onto the module. * Re-connected all flex print cables from Cobras to the driver board * Installed into the same connectors they were before (we skipped the same sets so as to not screw up MSIM) ---++ Fixing Electrical Issues on Test Bed * Corrections made: * Grounded Negative side (-) of Cobra power supply output to AC ground * Grounded test fixture to AC ground * Added ground wire from Master Electronics to Driver Board as a stand alone cable (the ground pins of the Comm connector were not included in the cable) ---+++ Checking out motor motion * Housekeeping and Set Frequency work fine * Cal does not appear to be working, but data is provided back somehow * Running all Cobras through range of motion: * SN 152 - Stage 2 does not engage the hard stop and does not move reliably. This Cobra should no longer be counted on for data. * SN 149 - Stage 2 does not engage hard stop. This Cobra should not be counted on for data. * SN 109 - Stage 2 does not move. It looks like it is contacting the Stage 2 housing, which might cause too much drag. * SN 121 Stage 1 moves very slowly. * SN 101 Stage 2 does not move. Potentially an issue with the electrical connection. * *ALL SET B COBRAS HAVE BEEN SET BY HAND TO NOT INTERFERE WITH THE SET A RANGE OF MOTION* -- Main.ChazMorantz - 25 Feb 2015
