Mini System Testbed (MSTB) Goals General Goals Test functionality of three entire modules (six boards). Test production cobra performance to keep up with...
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...
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....

Going back to 5C Generated new Centers Link Lengths after going cold (xml 13) Generated Motor Maps from last 5C data (23rd and 27th April) xml 14 JohannesGross...
Bug Hunting MSIM failed again after target run with newly generated targets. Positioner 41 had a calculated angle of 418 We found a new case for Hrands...
Rerunning Targets at 17 C Updated motor maps with new data from last target run and kicked off targets (yesterday). Reran centers script with phi further...
Target Testings Tedious Start Targets with newly produced centers and link lengths ran until 145. MSIM Crashed with new (unkow) error Produced new targets...
Getting Ready For Targets Again Identified Pos. 21 yesterday as the trouble maker. Link lengths of pos 21 are way off, centers too. Reran centers script...
Debugging findCentroids First problem with MSIM stalling out on findCentroids is due to a DLL problem. Workaround: run MSIM from MS Visual Studio findCentroids...
MSIM Problems Target Convergence Testing is still not succeeding. One issue with findCentroids was due to Matlab running on TB computer eating up too much RAM...
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...
Electronics Issues Over the past 2 weeks the electronics have been not behaving as expected and most of the time have behaved erratically (sometimes working normal...
Connect to camera using Remote CameraSetup NoCooling.lst Take test images using 2015 01 29 SingleExposure.lst Found .002s exposure was good for LED settings...
MOVE FROM CAHILL TO PHYSICS BUILDING HIGH BAY (SYNCOTRON) Peter and Charlie moved all hardware to the cold box located in Syncotron Test Cube w/ stages...
Released PFI CAD Models for Partner Use Attach CAD files to this page, `creating a link` to the file; organize into sections and headings as the list grows; comment...
Interval #8211; The combined time of the pulse duration and ringout time. One motor step occurs in one interval. Duration #8211; The length of time in which...
Update Testing Testing the new slow map updating on the 500 targets. Maps were generated using only the 600 targets from the two runs before. JohannesGross...
Testing new map updating Generated updated motor maps Increased ontime on pid 7 (without changing the motor map in order to test automated updating in the...
Fast Map Re ran script to generate fast maps with more care taken in phi angle during theta map loops (keep closer to 90deg than 180deg) Merged FAST maps...
Re Do of Centers and Link Lenghts Examination of MSIM output from FASTmotormap run from 10/10 reveals that phi and theta are drifting when they aren`t commanded...
Fast Motor Maps Switched cabling from Set B to Set C Removed filters from camera Loaded `090314 setC allmaps adj3.xml` into MSIM for last known link...
Continue Testing Since the results with previous targets were bad on several positioners, another test with the previous target set is run. ChazMorantz...
Testing Positioner 7 First Run: Maps Updated with adjustMap, ontimes increased on 7 (before they were not consistent with the mmaps) Second Run: Maps Updated...
