After the problem reported yesterday here.  I have replaced the picomotors GPIB driver with a similar one that I have found in the south end room.

At the beginning it seems to work fine and I was able to move the 3 degree of freedom of the 2'' telescope mirror in both direction both with the pad that using the PC.

Then, I have noticed that while connecting more than one cable to the driver output ports,  it starts showing some problems. 

Its behaviour becomes very strange and it is no loger possibile to move properly the selected channel neither from remote nor with the pad.

For exemple: if I send a remote command to move a specific channel the driver display shows correctly the name of the selected channel but it cannot move it and will instead make other picomotor ( connected to a different channel) to produce some noise.

I could not find any repetable pattern in such kind of strange behaviour while trying to test different combination of slots and cables. 

I only noticed that everything is working fine when only one cable is connected.

Since Raffaele suggested that it can be a cabling problem, I spent some times to check the connections but I haven't find anything wrong so far.

In the attachement there is a picture of the connection we made between the 2" telescope picomotor and the invacuum cable.
