AMMRL: Micro Imaging unit: gradients not working

Dear all,

After a couple of years of only using our imaging console for diffusion,
I switched to our Micro5 head for imaging last week and to Paravision.
Of course after a few years, I'm a bit rusty (especially with
PV ...). The problem is that I can't even get a simple
scout (tripilot) ... It looks like the gradients are not pulsing. I
can't hear them, I can't see them on the console and
I'm getting a single white dot in the middle of my scout.

-Wobb, REF and SHIM works fine within PV. No problem there.
-X, Y and Z are enabled (green lights).
-Diffusion is working on TS (Micro5 head, water sample, Z-gradient only)
-I switched from 60A to 40A in SetPre when I switched to Micro 5 head

What am I missing?

Cheers,

Celine
