Hi Mark and all,
I used sscan-2-10-1( 2D scan ), base 3.15.
I always got "Waiting for pv's to connect" after I clicked the "scan" in scan1.
But it work fine when I disable the saveData in st.cmd with the same setting. It could do the scan 1 and scan 2.
So I think the error was saveData. But saveData should be easy. The error was "I/O error, can't open file" though I am root.
The following was some strange message I got.
When I set the parameters, I got these message in st.cmd.

Then I click the stop button to stop. I saw these.
It should not be like these. I do have the permission since I am always root.
