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...
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...
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...
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...
