This is a 4mm open box calibration test. For some reason when loading the file in pronterface this is the result I get (attachment). I've tried different settings all with the same result.
Any ideas as to what might be going on?

Thanks in advanced

Some times the answer to a problem is so obvious its easy to overlook. Kinda like loosing your glasses on your head. I had unchecked the detect thin walls for a project a few weeks ago. Since then I updated slic3r and installed a new hot end.
Oh well.
Thanks for taking the time to look.
