After checking the cable of T6 & T7 it seems that there were in fact an inversion during experiment e748. T6 is the bottom one, and T7 the top one.
During e748, it seems that there were some difference regarding the position, between the hardware and software position...
If it was the case, it would mean that it is T6 that has the time calibration problem, not T7.
re-
In conclusion, it is T6 that has both the time calibration problem on X and Y, and the weird signal seen during the calibration.
EDIT 4/04/18 : For the experiment e748 and before the time calibration, the inversion had been made, as a conclusion what was previously stated is wrong, it is T7 that has no time calibration... Anyhow, wee will re-do the time calibration for T6 and T7 to check if the problem are still present. |
