I have the feeling I may be needing more of it if this works out as well as I think it will.
]]>my point is, some people buy that program expecting it to be cure-all to all their 3d printing problems, when it isn't.
One still needs to take the time to properly calibrate & maintain the printer, and learn how to properly use the software of choice.
I have spent a lot of time doing just that. I know what my printer(s) is(are) capable of and have learned how to use the software I have chosen to run it(them), and I am still learning things as I go (never stop learning!).
Hardware, however, is a completely different issue.
]]>last I tried slicer I dont think it used multicores for the post processing. maybe its changed, but $150 for CAM software is a drop in the bucket compared to hardware and CAD licenses
]]>I don't use S3D - see no reason to spend that kind of money when RH and Slic3r do a great job for me.
and somehow i think your speed is in mm/min, not mm/sec, lol.
also using E3D v6 with a 0.4 nozzle. I am currently using 1.75mm retraction - thinking about bumping that up to 2 tho... and base print speed is 35mm/sec (2100mm/min), extruder temp at 250, bed at 55 with the glue stick.
Am having pretty good success with horizontal holes and overhangs - it isn't drooping at all, just kind of blobby when traveling between areas
I printed some door lock parts this weekend at 100% and the supports were really difficult to remove and the blobbing at the top of the last portion extruded was bad. some sand paper took care of it, I just wonder if its my settings. part can be seen here. http://www.thingiverse.com/thing:1306202
E3d v6 .4 nozzle. 4mm retraction in simplify3d, 1800mm/s speed. 247/50 temp.
]]>have been running more parts with the nylon and decided the hairspray wasn't quite holding well enough - would occasionally have an end lift and this stuff is too expensive to be dealing with that. Dug out the trusty old glue sticks and tried that - bingo! almost holds too well! Even with the bed completely cold I had to use a razor blade to get the parts off.

]]>Also I carry 910 for $29.99:
]]>But anyway, in the quest for something more suitable I ordered a roll of the Taulman 910 Nylon and a roll of ABS based CF filament from another company (will do a proper review of that one later)
The spool the Taulman comes on is TINY! I could not fit it on my regular spool holder (3/4" ID PVC pipe over threaded rod, running on bearings in printed adapters) - I had to use the smaller version from my FT prusa (1/2" ID pipe, also on bearings) and that barely fit - had to remove the adapter from one end, load the spool, then re-install the bearing adapter & nuts that hold it all in place
Calibrations: went as usual - measured and averaged the filament diameter, print calibration cube, tweak settings, etc...
Taulman recommendations:
Extruder: 245-260
Bed: can be either cold, or warmed to 40C with a 50/50mix of PVA glue & water
Retraction: 0.1mm for each 0.1mm of nozzle size (0.4 nozzle would be 0.4mm of retraction) < yeah, right LOL
My actual settings:
Extruder: 249C (E3D v6)
Bed: 52C with a generous application of Aqua Net hairspray (may reduce this a bit after some more experimentation)
Retraction: my normal for ABS = 0.75mm - doubled it to 1.5mm and could stand a little more, but don't want to push it too high and end up with heat creep problems...
the stuff oozes like crazy at 245C, but to get good layer adhesion, I had to bump it up to 249C. increasing retraction has helped with the oozing/blobbing, but still get a fair amount...
Otherwise, I like this stuff. It prints easily, and stayed on the bed with the hairspray just fine. Did not need to add a brim to the parts I printed with it (had to have a brim with the ABS as they are small contact area items). Just the oozing is a "problem" and it isn't so terrible that I can't deal with it.
the parts turned out well and seem to be MUCH stronger than their ABS counterparts. They still need a little more tweaking (around screw holes mostly), but I think we may have a winner with this filament. Quite happy with it overall.
5 of the 8 pieces that make up the cab roll cage...
a closeup of the ooze blobbing, even after increasing retraction...
Cost was $32.00 + $5.50 shipping for a total of $37.50 for a 1lb spool (roughly 0.5kg) ordered thru Octave via Amazon...
and just because - spool size comparison... the old Octave spool, a standard sized Hatchbox spool, and the mini spool of the Taulman 910...
