I am trying to run a windows batch file from kmotion cnc using a user but with the execute pc.

The batch file reads current state from a file, and based on that state sends various options to a windows console app, it also writes back the state change to the file.

It works fine when run manually, but gives an error from motion:

"error

return code = 255

abort"

Is this a windows security setting perhaps?

Thanks,

Colin
