Well I guess I better figure out how to turn on that cooling fan mounted to the extruders on the FFCPro, and study makerware.

The particular model prints perfect if split it, as therefore have wider base area / more layer cooling - but that's a pain. And printed thinner base diameter models last night with no drama BUT that was only due again to base coverage area meaning layers could cool.

So looks like I have some work ahead of me today, and thanks for all the feedback, tried uploading the actual STL to this reply but just wouldn't work.

Cheers
