Working on trying to dial in carbon fiber abs. Going well so far but I needed to add some extra restart distance to avoid gaps after retract. Anybody have any pointers for me?
Current settings:
70mm/S 85% outer perimeter
240c hot end
70c bed (for now, will go up but it sticks really well to PEI even at 70C)
5.5mm retract @ 60mm/s, 0.5mm extra restart distance
Wish me luck 
Hardened e3d nozzle?
@Matt_Miller I will be honest, I bought some cheap stainless ones of aliexpress a while back when I got the deal on this filament (super discounted). I wanted to try it out first to see if it is something I would like. And I do, so time to get some proper Official E3D hardened ones now
I am also looking at this stuff with interest: http://www.3dxtech.com/glass-fiber-reinforced-amphora-petg-filament/
I love PETG (my favorite by far). But want a little stiffer parts. Looks like a winning combo and better colors than just cf-petg has to offer.
Edit: Just re-read and noticed the comment about color. I guess that’s why the 3dxtech link is glass fibre as the carbon will always have black specs.
That one is glass fiber, which is an interesting idea too. This one looks like carbon http://www.3dxtech.com/carbon-fiber-reinforced-petg-3d-printing-filament/ Have you used their filamnet before? I’ve never heard of them. Of course there’s also ColorFab http://colorfabb.com/xt-cf20 which looks to be the same polymer. I thought Amphora was some “new” polymer? Is it just PETG or PET(some other modifier)?
I have used their ABS before (via push plastic). Great stuff.
Well I just found out the hard way they miss labeled it, and I’m printing carbon fiber PLA not carbon fiber abs. I was wondering why I was getting funny extrusion. Dropped the temp down to 205 and turned on the fan and getting much better results, unfortunately I have no use for PLA 
was about to say. i havent heard of ABS carbon fiber infused filament yet 
@Jim_Stone there is lots of it actually. I like 3dxtech filament but I’ve really only printed a couple kg of the red stuff (carbon nano tubes) and a sample of their CF filled ABS. CF filled filament are definitely more problematic through 0.4 mm noodles though @Eclsnowman . They don’t flow so well through small nozzles. It can be worked around, but consistency is tough
They say it will ablade the head unless I have the right type in as little as a quarter role
@Glenn_West it’s the truth. Turns a 0.4mm brass nozzle into a 0.6mm in about 100g or less (speaking from experience)
I’m doing a crash course in CF-PETG this week. I am prepared with hardened nozzles and drive wheels, but the part is big and time is short., with no experience with PETG on this machine, hot end or extruder configuration.
Wow I worry about the copper pla i have.
Guess I better change to the new nozzle before printing
@Chris_Brent I wanted to print a new carriage for my enclosed printer. PLA doesn’t cut the mustard when the çhamber is 50-55C. Plus I just tendnot to like PLA. It’s a preference really, back from my e3d v5 days when I used to fight jams alot.
@Eclsnowman I was given some test filament by William at http://INTSERVO.COM. It is something new they are testing, carbon fiber filled nylon filament. So at least very soon there will be carbon fiber in nearly all common filament types. Same proviso applies for all nylon, it will warp without proper environmental controls, similar but not as severe as ABS. You might ask him about it.
Prints very light parts even at 100% infill and it is much stiffer than straight nylon filament. Does need heat, had to print at 260°C.
Plus the video was interesting seeing how your two heatsink fans spin at different rates.
So how are your prints? Can we see some end results?
Have you ever ordered CARBONX Carbon Fiber ABS 3D from Amazon?
