This is the temp tower of my wood print experiment Cand even se much difference. It goes from 260 to 190. Below 225 gets really flimsy and above 240 melts. But even 230, the “best” one is really bad, and I’m not talking about retraction. Even the layers that melt are inconsistent.
Also it’s not humidity since the filament was in a filament dryer for.16hours.
can someone think of anything else?
Looks like a partial clog and too fast at the same time. A .8 nozzle lets a lot of material flow, try slowing down after checking for a clog.
Yeah that immediately looks way under-extruded to me.
Also that wood stuff (from what I read) clogs terribly.
Yes that’s why I’m using a .8 nozzle lol
Can be a clog. I read that wood should be faster so.it wouldn’t clog, but it could be this too . I’ll try slowing down and checking the nozzle! thanks for the idea!
You can’t both push a bunch of extra material and print faster. Hotends have volumetric limits.
Are you sure the gcode actually makes the printer change temps? Good thing to double check since it looks the same throughout
If you focus only on the little pylon within the circle you can see a clear trend.
hum ill check but I used orca native temp tower and chrcked through the print? it didi chsnge. could it be a hardware problem?
I don’t know what your setup is but that looks to me like you need a higher flow melt zone and better extruder grip. I was able to get out of a similar situation with particle filled filaments using this: kevinakasam.com/papilio/ and further improvement with a hall effect filament width sensor but the tinkering for that was an actual nightmare.
wood filament is also just cursed. the improvement to regular filament was much better while the particle filaments just went from similr to your wood filament to tolerable.
oh that’s interesting my extruder is indeed kind of shitty. I’ll take a look at this thanks
This is how my wood PLA+ prints used to look too. Your extruder is almost 100% the issue. These filaments are spongy and don’t extrude well. Try toying with your extruder tension and if that fails get a BMG knockoff
Looks to me like the plastic isn’t getting hot enough fast enough.
Is it just wood filament that isn’t printing right? Can you print pla or whatever on the .8mm?
Does the filament brand suggest a range that’s higher than you normally print at?
No, crealty wood. If its too hot it burns
What are max print speed and volumetric set to?
For some filaments (silk PLA) I’ve had to slow things down (120mm/s max print speed and 10mm3/s max volumetric speed) or it comes out horrible. Only used 0.4 nozzles so far though.
my print speed is at 60mm
I am definitely thinking you have a partial clog. Get that sorted out first, then run flow rate tests as well
Have you tried adjusting the e steps?

Did you change the nozzle setting in your slicer to 0.8? They usually default to 0.4
It definitely looks under extruded.
