Hello, could somebody include a sidenote in the servo-to-go stg documentation here http://www.linuxcnc.org/docs/html/drivers/servo_to_go.html that the opamps on the stg card do not work with all newer atx power supplies that use modern switch mode DC-DC converters?
It took me a while to figure out when I wanted to replace a broken power supply why the stg card would just output a constant voltage regardless of what the driver was commanding it to do. Has to do with the emirr (emi rejection ratio) of the opamps to the noise introduced by the switch mode dc dc converter in the atx power supply to the Vs voltage of the opamp. Older atx power supplies with linear regulators will work fine with a stg card. BR Max. ------------------------------------------------------------------------------ New Year. New Location.
