Game time: Spot the difference
-
@jens55 Oh, but there is a huge printing difference...
-
so actually its non of the stated.
Yesterday I tried to print this model multiple times with different settings ... no changes. Over night I dried a smaller role of filament (same manufacuterer same filament) but no I get these good results ... so simply ... wet filament -
Lol...the difference is in the homing (I was reading your threads)
-
Exactly .... no difference in actual printing, only in homing.
Again "trick question and not fair"
The original question was fair though ..... -

@taconite Nice one. I need to get a food dehydrator to dry out all the PLA thatโs been in my loft for the last few years! Is that what you used?

@droftarts I've used a convection oven a few times. Just be careful with the temps. My oven doesn't go very low, so I heat it up and turn if off and heat it up and turn it off a few times over an hour or so. I use a remote meat thermometer to keep an eye on the temps.
-
I use a food dehydrator that controls the temperature. I also have an older one but it doesn't control temperature so I don't use it for drying filament.
Having said all that I find that moist filament is rare for PLA and PETG. I leave the spools on the machine when I am not printing. At least on PLA there is a situation where the filament gets extremely fragile in the section from the spool to the extruder so it's got to be treated careful or reloading is required. There is no difference in material once it's been melted. IMHO this phenomena is caused by exposure to air after getting micro fractures from un-spooling. I takes about a week of sitting before going fragile. -
Filament was PETG. The thing is, that there is a quite high humidity in my basement. That's why I use a little pizza oven to dry my filament.
And I had a problem with to high temps aswell and because of that a role of filament fused together
-
@taconite I Over heated and semi-melted a roll of PLA in a kitchen oven! Most was salvaged, but was brittle. I printed extruders out of it, but they kept breaking!

is there sufficient airflow in those ovens to circulate the air out as it saturates with moisture from the filament?
-
@bearer hard to say ... there are some holes in the top of the door but when I dry filament I need to set the timer every hour, while doing that I open the door to let moisture escape
@droftarts yeah it gets very brittle. Once the filament strands were slightly melted together and I didn't notice it until the filament broke during printing.
