Just a few observations...

For those that are struggling with their prints thinking it is the machine. Today I was attempting to print a rather large ring and the first attempt failed. I was on a roll printing and everything was working perfect!! Well back to the computer I went and looked at the piece. As I was contemplating what the problem might be I remembered I didn't check it with Netfab mainly because I was doing so well for the past month. Anyway the model went through the Rhino STL just fine and normally when this happens the print works. I checked it in Netfab and to my surprise it was a total mess. Everywhere there was red the print failed. When I looked at the STL file size I noticed it was extremely small @ 4290 kb . Most of my rings this size with supports and using a very fine STL Mesh for resolution are running 22000-40000 kbs.
The ring Booleaned fine and everything looked perfect so I ran just the ring through Netfab and it was perfect with no issues. So I narrowed it down to the supports. I started looking at them and decided to start from scratch. After decreasing the steep angles on a few of the supports, removing 2 straight supports then replacing them with angled supports, and reducing size of the base support a little WALLAH everything checked out right in Netfab!!

1. After you have done this a while I think you will be able to look at your file size and know if there might be a problem.
2. Always check with Netfab even if you think you have a good STL you might be surprised.
3. It is almost always about the support system, Repeat It is almost always the support system!!

I have learned that printers will spit out the food if it doesnt taste good!!

Do you ever have failures even after running it through netfabb?

Regarding supports, you do them your self or via a program?
Thanks for the info

Yes if not supported right. I am getting better. No problems with the lighter rings, some of the heavier pieces have given me issues.

I am using rhino and rhino gold and RG has a supports module. I also make my on bridges and supports depending on the piece.
