### PROBLEMS ###
The south metrology Current is Bad.
South metrology signal looks weaker than North on the webcam.

LDC server displays :
Crown wedge : 0.000 ??
Air offset : 0. (not -1m)
the blocks are not in position
LDC fixed with changing the rate and reindexing (advice in the bugshooting page).

Cart stopped at 12.30 meters
When I move the cart beyond 12.30 m , the "north laser heater current turns out of range" and it make the cart stop. I managed to go further with zcoarse commands. 

Impossible to acquire the star on North. Looking at the LED at the back of the sid, something looks misaligned. I tried to use the laser with astromod -a but spiral search didn't work. I searched a bit manually but didn t manage to find the laser spot. Try again tomorrow.


Envgtk indicates for El-1050 a RH of 15%. I m not sure what it represents because  ATCA says 79%.


MAIN ISSUE

Impossible to slew the cart back to zero, "carriage has stopped unexpectedly" happened every 10cm !.
After having typed quite a few times the unstop/cab_reset/zcoarse commands,
I left the cart where it was (about 15 meters North) when I lost the North metrology. 

I guess the first thing to do tomorrow would be to get back the metrology, then the cart position and finally look at the North beam alignement.
