Just a small addition to this design. It's quite good but you must remember that the plastic expands upon entry in the first hot area. This needs to be large enough to accomodate that beyond the liner which is slippery enough to contain and funnel it. 1.75mm filament needs a melt chamber of 2mm and 3mm filament requires 3.4mm to avoid breaking against the walls. Try it and you will see your feeby KreAture - General
I notice often that slic3r will produce code that can choke my hotend. I have to carefully limit it's extrusion width on different parts like initial layer, and calculate that with it's first layer height and speed to make sure my hotend can handle it. Currently my hotend will handle PLA at 660mm^3/min (11 mm^3/sec) which is fast, but not faster than my printer can move... It does ABS faster thouby KreAture - Slic3r
The support material now detects overhangs based on angles. If it could also see if the area to be supported is itself supported and the stretches are within some settable parameter, it could decide to not use support material within simple cutouts/holes but still have it enabled for demanding build overhangs in free-space and such. Not sure if this is simple to do, but I know slic3r already detby KreAture - Slic3r
