Re: LISA Simpson
If you plan to heat the chamber then fiberglass, carbon-fiber, metal, etc would be a good idea.

I doubt I'll heat it to anything to extreme. I'd like to be able to use ABS printed parts. It looks like: [www.hardwarestore.com] will glue fiberglass to ABS. Assuming it's a machine with: 1) 24"...

So if I go with the 2x2x1/4 material, it should have an ID of roughly 1.5x1.5. I could print a part with a stub on it that would mate with the end of the rectangular tube. Maybe some sort of flange as...

The software is likely to turn out to be more like a 3D CNC setup than like the auto pilot stuff we use for printing. There's a lot of operator involvement in deciding what to do when and how to do it...

[attachment 23023 tree.jpg] @uncle_bob: My plan for auto-pilot is to slice where layers meet surfaces within 45 degrees of perpendicular. I am not too worried. I know it can be done. Time is all I need.

@uncle_bob: Can you give me an example? In my mind I think I can come up with a generic solution. Just work your way up the surfaces ( do what you want on the interior) and obey the 45 degree rule....

I'm more familiar with the issues on a CNC than on a printer. You are correct that it's often a "clearance for the extruder" (or tool) sort of thing. On a CNC it's - chop this out ( or rotate the...
