New Firmware Version Rev. D. Keith provided new Firmware for FPGA and Comm board. Installed on 3/24 Ran first target test with new Firmware, 16 03 25...
Current config COBRA PID RAIL Board POSITION POSITION EMPTY 01 01 01 C1544 03 02...
Mini System Testbed (MSTB) Goals General Goals Test functionality of three entire modules (six boards). Test production cobra performance to keep up with...
Collision Avoidance Ran first test with colliding cobras. Partially worked, targets for some positioners were off (roughly 1 20). From the first to...
Cold Test EM RAIL LOG COBRA RAIL Board INVERTED Current Performance POSITION POSITION MSIM ID PID...
List of causes for weak positioner performance: In 15 10 13 16 54 58 TargetRun PID1 shows low performance due to a home angle offset. Negative home angle leads...
Tested Target Runs with no homing Tested no homing first on the 3 7 11 set `15 10 07 16 33 23 TargetRun` and `15 10 09 15 02 14 TargetRun` are 1...
Target Runs, Debugging After Chaz and Johannes had seen some images being taken before move finished (12000 steps moves) we added back the wait command Johannes...
Move to Downs 5 Moved hardware last week out of cold box and down to lab 5. Hrand is working on MSIM function to generate commands for setting center positions...
PID 9 : C1522 PID 31: C1521 After we found some potential problems with the board, we decided to swap the boards. Plugged in all positioners now at the...
ran updatemotormaps on last run: 15 09 09 17 18 13 TargetRun New map: 2015 09 03 NSTMaps V06.xml Edited pid 9 map to set first theta bins equal to...
Verified positioners in theta reverse hardstop by hand. Moved phi to intermediate position Ran several images without motion in between to measure joint angle stability...
Checked PID 9 shaft coupler and it is very firmly bonded. So the sticky spot noticed from targets last night is probably not a shaft coupler issue. Checked tension...
Electronics Failure on PID 9 Yesterday PID 9 stopped working after initially working We probed the output signal of PID 9 and saw a capacitive behaviour...
Status description Johannes was away 3 weeks. Chaz and Hrand tested system with camera to `see` reverse moves. On 8/31/15 Hrand, Thomas, Matt, Chaz...
Target Testing Debug Found evidence for non moving positioners within target tests. E.g. PID 41 in Test 15 07 28 17 35 02 TargetRun did not move 192 times even...
Electronics and MSIM Testing CAL from MSIM seems to be much slower searching for reason and checking on trustworthiness of data. Peter wants to see a...
FPGA Firmware Update Put firmware on fpga, new software on comm board. tested Cal Command low level Pos. 123 S1 resistors are broken Pos....
Second Temperature Test Cycle After the first cycle (RT 17 5 5 1 RT) we plan to walk through the temp points in the same order At 5C we used the...
Check Out Positioner Failing Phenomen Charlie, Hrand and Matt looked into the reasons why some positioners were not working during some of the cold tests....
