Re: Filament grinding

Another factor is if you are printing a large object your cooling fan is pulling in air off the 'warm' bed, so you are actually blow about 50C air over the cold end. I use an downward angled cooling fan now to help with this issue myself. Oh that's interesting. Did you print a mod to get this downw...

Re: Filament grinding

Is there anything in the environment that may contribute to higher-than-expected temperatures around the extruder? What is the ambient temperature in the room by the printer? Things to consider: - Is the printer in direct sunlight? - under or near a warm-air vent? - In an enclosure, a closet, or a ...

Re: Filament grinding

Are you using the stock settings aside from temperature or have you made other adjustments in addition to the experimenting with retractions you initially mentioned? Also since your other models all came out well I have to ask, have you tried a variety of larger models or have you just been experim...

Re: Filament grinding

Latest test just failed. About an hour or two in. Left the enclosure off, printing at 195 degrees, and while I didn't have a small fan to point at the printer, the room does have a ceiling fan going. I'll see about bringing a small fan from work tomorrow. Also, I opened up a brand new box of Inland ...

Re: Filament grinding

Filament.jpg The purple pictured here is the polymaker, The gray is Inland. I have many other failed examples, but they basically look the same and came from many different rolls, as this problem seem to slowly ...creep...up on me, and didn't happen all the time, at first. Also of note, In december...

Re: Filament grinding

So then I tried a very large item, something that would take 8 hours plus.

Tried it twice as you can see. These failed about 1-2 hours in.

Re: Filament grinding

Then I tried a smallish item that would take 4-5 hours to print.

Success on both! Not perfect but not failures.

Re: Filament grinding

The fan does power on when I turn the machine on.

Doing a test now with the temperture turned down to 195. I use alot of Inland and Polymaker. See pictures below.

After starting over with the latest version of Cura and it's base settings I tried a Rocktopus

Filament grinding

I've had my Taz 6 for over a year and it's been great. But lately anything I print that takes more then an hour or two fails due to the filiment getting ground away as it's turned. I'd done a fair bit of searching and see this problem happen for mutliple reasons, but I can't seem to nail down my pro...

Re: First layer issues?

I lowered it to .2 and lo and behold, much better quality prints! Thanks everyone for the suggestions, I still learned a few interestin...
