Hi Geoff
i tried the replicter software, and after reading what you said about Makerware, I down loaded it and have used it more or less from the start.
the problem seems to be worse if I increase the width of the side panel.
the item I'm trying to get right is a three sided body for a truck.
its about 35mm wide by 33mm long by 18mm tall, and 2mm thick.
the drawing looks okay but has it is not solid I assumed increasing the infill to 100% would fill in the gaps.
i was wondering if it's to do with the slicing, ie not seeing it all.
or the travell speed when printing!
Regards
John
