A. So basically you want to Kickstarter to get people to buy you a printer?
B. If you are a bit of a film maker, how do you not have video equipment already?
C. Do you have any experience building 3D printers?

If you are a bit of a film maker, how do you not have video equipment already? Save your money, BUY your own printer, and build it. There are already plenty of assembly videos of many different printers already on the net.

About the same, maybe a little less surface quality at 10mm/s, can't go much faster without printing multiples for additional cooling time at this scale.
With my hot end, a Wildseyed variant, and at this scale, printing faster gives me lower quality, even with a fan running. At a faster speed the layers do not have enough time to cool, and the subsequent layers start dragging and disto

That may be backlash compensation being too much. I seem to get variances in backlash relative to print speed.

Glad to see that worked for you.
Working on printing smaller currently, I'm running into either z-wobble, layer smashing due to temp expansion between bed and hot end, varying feed matial quality, or a combination of all 3, producing some layer banding. The ridges in my prints are several layers thick, thinking z-wobble mostly.

You will loose dimension to material shrinkage, and a cylinder will cool dimensionally different than a cube due to varying tension between layer angles and the curve on the inner and outer perimeters.
I did have my machine calibrated with a dial indicator down to .01mm in the X and Y, and could mount a pen to the X carriage and draw dimensionally perfect (+/-.05mm) circles and squares. But when

under carve/edge width and under dimension/measured width of extrusion, set these values to the same as your nozzle diameter.
You may have to tweak your flow rate a bit, but overall I'm getting better results.
I'm running a .25mm nozzle, and get an 'in air' extrusion width of .33mm, but I get much better path to path overlap and stronger parts using .25mm for extrusion width in SF.

Does anyone know of an alternative support material plugin?
It took me the better half of a day to get usable settings with SF50.
I ended up with a feed rate ratio of 0.0025 to get the base layer to run at the same speed as my print feed rate.
The settings affect each other in a way that just does not make sense.
It's also generating support material completely outside of the model that suppo

That is from your extrusion width being to wide to do a pass in small areas.
Example, if you have a 1.5 mm wall, and an extrusion width of .6, the perimeter passes will take up 1.2mm leaving a .3mm gap that your slicing software will not infill due to the infill space being smaller than your extrusion width.
I've been running my extrusion width to be the same as my nozzle diameter of .25mm and

Drop down to a .35 or .3 mm layer height. I'm running a .25 nozzle and see a world of difference between a .25 and .2 layer. My 'ideal' layer height is .15 mm with my nozzle.
While you can print at a layer height of your nozzle, layer to layer adhesion will be weak, and blobs and other print problems are unavoidable.

That last photo looks like your extruder is skipping steps, or if you are set up with a bowden style extruder that the filament is binding or buckling in the feed tube.
Slic3r will not vary the extrusion rate like that in a layer.

Could also come from inconsistant filament diameter. I have some black ABS from reprapper.com that varies way too much, +/- .5mm at some places on 1.75mm filament, not good.

I get this in my prints from the combined thermal expansion of the bed and hot-end due to temperature fluctuations.
I think most of my flexing is in my heated bed, I can print on a cold bed with ABS juice and get much better consistancy layer to layer.
I'm running a PID temperature controller on my hot end, which is a beast to get minimal temp fluctuations. When the temp runs high or low from s

Had infill overlap over perimeter set lower than .65, which SF warns during processing. Was running into backlash issue causing infill to not meet perimeter loops. Now running with backlash correction.
Had the time tonite to run quick test codes to figure it out.

Bridge speed ratio of .6, but no feedrate change for bridge areas. Refering to that as a bug, not the overhang layer infill.
It looks to me that solid bridge layer is calculating from the extrusion width, not the total perimeter.
Running a .25 mm nozzle, 0.1 mm layer height, 6 perimeter loops, no overhangs layer to layer that are more than 1mm.

I'm not seeing my gcode change feedrate when bridging with 'infill in direction of bridge' turned off, but it does solid fill over bridge areas.
Turned off infill in direction because skeinforge also thinks overhangs are bridges and will fill those layers solid as well.
Is this a bug?

Skeinforge based infill does not output the infill lines parallel to each other except for 100% infill.
Slic3r does infill lines parallel reguardless of % infill.
KISSlicer infill is a honeycomb type infill without a selectable infill pattern.

I do not like SCAD generated stl files at all. I've had to clean, patch, and modify EVERY SCAD file I've pulled off of Thingiverse.
The geometry triangulation is HORRIBLE!
I wanted a tapered shoulder on this gear, just about had to rebuild the entire mesh in 3ds Max.
Left gear is SCAD or OpenCAD, both suck at face triangulation, the gear on the right is my corrected mesh. My gear is 75% in dia
