I get the message - 'cann't write file' instantly like it does not even try to do anything it just bombs out with that error. For grins, I switch to several other cfg's like Peopoly Phenom and it printed out just fine. I rolled back to version 1.6.3.4 Beta and it just succeeded in writing the slice file so I am about to try and print that.
I have attached the file I am trying to print in case someone else wants to try using 1.8.1
