Thanks, I used a glue stick for adhesion and it seems to be working very well. Funny thing, I did abort the print job, let it cool off and restarted it. Now it has a little over three hours. I think the first few layers just take forever. I had never used Nylon before, the guy I got the printer from gave me some. From little I can tell so far I really like it....I will check the compatibility button next time.
