You could also do a search, plenty of topics about it here. The key with PLA is pre drying.

Yes, I got a melt filter with my order, and it is currently installed. Should i drill the melt filter nozzle out, or would it be wiser to just get a larger one from you? I just ordered a filawinder, so you could throw the new nozzle in with that order.

Also, regarding your attempt at recycling, you should be careful with dry ice and blenders. Parts of the blender itself may become brittle if you tried to blend plastic with dry ice. There have been previous efforts to improve that process -- here's a good one: http://ubc-rapid.com/blog/improvements- … a-blender/

I built my own extruder initially to recycle my prints, but after I found ebay listings like this, it really didn't make sense to sink all that work into recycling the prints themselves. I bought a 16 lb box for $25 a few weeks ago, and even with 100% recycled material, it comes out beautifully, no foreign material, very high quality filament. Just some food for thought...

One solution is to increase the nozzle hole size, because they are conservatively drilled for a <1.75mm typical diameter.

The other main point is: One kind of ABS are you using? The type will matter alot, as they have different swell factors.  It looks like you did mention the two types (sorry I just noticed this.) I'm surprised there is no variance between the two.

Another thing to consider is: Perhaps you can use the smaller diameter filament? Personally I am all for a smaller filament diameter, especially if you are not running a bowden setup and can more easily prevent kinking.

Major pro of smaller filament:
It requires less torque than the bigger filament to bring through the nozzle. Meaningfully.
It is similar to having a gear ratio on your stepper motor. So less moire. Not majorly different, but 1.54mm vs 1.75mm is about 18% different volumetrically.  Gear ratio = less moire, but also extracting more torque from the motor because the extruders are substantially below max rpm.

Major cons:
potential for kinking esp with a system sized for 1.75mm filament.
greater surface area to volume, potentially problematic for hydrophillic filaments like PLA and Nylon

     I am using the newest version of the filastruder, GP-35, a 1.75mm melt filter nozzle, and my filastruder is about 5 feet off the ground. When I was using the MG94, I still got the same diameters. I have also used tempetures from 173-180 with no luck. If needed I can provide video and pictures. At this point I am thinking it may be the nozzle, but I am not sure.
