Topic: noob makes good

I am finally able to run the Filasrtuder produced filament non-stop in my printer.

After having wasted a kilo of pellets and having to take the torch to many nozzles I think I have it sorted.

Number one is to get the $25 nozzle with melt filter part. I don't see anyway one can do without that given all the contaminates that can get into the product one way or another.

Number two is never run the printer hot end higher than 190 indicated and never pre-heat. The OS printing stuff smokes off and crystalizes in a heartbeat. That is way different from the Octave stuff that you can leave oozing at 200 for hours at a time.

And finally, the dinky PC fan is no good, I use a regular floor fan and that produces enough air to cool it in time as well as  enough vibration to keep things moving when ramen starts to creep in.

As an aside, I just wind the finished filament into a figure eight and stuff it in a can the right way and if feeds fine. If you have ever coiled an anchor rode you know what I mean.

YMMV.

Now I am onto mastering master batch, yeah!

Thanks Tim!

Oh yeah, one other thing, I used carbonized felt to insulate all the hot parts. It makes for less third degree burns and can be removed and replaced many times unlike the cheesy fiberglass pipe wrap that comes with. Half a of it does the barrel and nozzle and costs 15 bucks. And you can you can use these other half to handle parts you have to blow torch to clean them.

foofoodog,

Where did you get the carbonized felt from?

Re: noob makes good

For the record I have left my printer hot end idle at 204C (solidoodle temperature) for hours without issue running MG94, and I use the stock insulation/fan, and haven't seen ramen in over a year, with well over 1,000 hours of runtime. Proper guide placement is important, and the correct solution - not a box fan.... but like you said, I guess YMMV. I'm glad its working out for you, that's what matters most.

By the way, not sure why you're getting "third degree burns" - do you also insulate the surface of your stove? Why not just avoid touching hot parts?

Filastruder - the robust, inexpensive filament extruder
E3Dv6 All Metal Hotend - the premier 3D printing hotend

Once you have the hot parts covered with that the PID calms down some.
Beside that, you can pick the thing up by the barrel if you have to.

Good find on that felt.
