Hi
I want to pilot a laser with a linux computer and with galvanometers bought on ebay (25 k galvo scanner). I had to add a DAC MCP4822 to have output between 0 and 5V and I made the assembly below to have output between ~-5V and ~+5V

When I connect the ouput to the driver nothing happens when I change the voltage :-(
Thanks for any hint
