8 years ago PseudoSingle axes - like your h, k, and l - have an internal "target" position that gets set if you move that axis specifically there (see here)PseudoPositioner (e.g., tardis) to a fully-specified position (in this case, an hkl position), those target values would not get set (*)(*) Perhaps we should reconsider this.

8 years ago Thanks for the response @klauer. @cmazzoli and I will try to digest.
In the mean time, we tried to use a d3scan. it looks like only two of the 3 motor positions are set, but the two that are set, are correct.

FailedStatus: MoveStatus(done=True, pos=tardis, elapsed=0.0, success=False, settle_time=0.0)
@klauer I looked at the collected data and [tardis_h, tardis_k, and tardis_l] are recorded in the database as what one would expect (per the plan). However, I am puzzled by the output from tardis.position before and after the dscan() because dscan() is supposed to return to the position prior to scan execution. Plus, not seeing the peak on the images during and immediately after the scan tells me that there is something strange. We will test more tomorrow and get back to you.
| tardis_h | 0.00421 | 0 | 0 |
| tardis_k | -0.33759 | 0 | 0 |
| tardis_l | 1.34048 | 0 | 0 || tardis_h | 0.00420 | 0 | 0 |
| tardis_k | -0.31000 | 0 | 0 |
| tardis_l | 1.34048 | 0 | 0 |
Maybe there is some arguments to be made for during the scan regarding triggering, but the behavior at scan cleanup is not what we expect.

8 years ago Here is the data recorded in data broker. K should be -0.33759 and not -0.31 as below. I assume that the zeros are dropped from K when recorded? @cmazzoli, @stuwilkins - thoughts?
Also, maybe the NaN at the beginning and end of the scan may be related to this issue, as Tardis is a pseudo motor and moves many. Obviously, this could have impact on CSX for sy and sz. See https://github.com/NSLS-II/Bug-Reports/issues/138 4th comment.

If you want more data, I can generate it. Do you have specific requests?

8 years ago Ok @tacaswell, you are right. @klauer, when will you have time in the next two weeks? (09/08-09 I am busy, for the rest I will find the time)

8 years ago I have some time tomorrow morning. @danielballan / @tacaswell, who wants to be on the receiving end of the hkl brain dump?
Scanning ascan with tardis.l changes tardis.k 'motor'. We thought that this worked in the past (constant tardis.h and tardis.k during the tardis.l scan).
Below, K= -0.33759 at the start of the scan. After the scan, it returns to the starting point. K = -0.3100. This is a huge error in reciprocal space. When the scan returned to the "starting position", the spot was not on the detector (and was never seen during the scan). IF it is present the entire timre or just a few frames is what we would need to know so accuracy is important.
Users moved on, but there could be a potiential to fake with tardis.h and k held constant. Needs to be tested.
