So this filament was dried. It only yielded 2g of moisture at 50c for 12 hours. That did not seem to make a difference.
I’m at the point of declaring this a total loss as a defective filament. I’m pissed at myself because I purchased this during an Amazon flash sale and forgot I had it. It’s now outside the return window.
Anyone have any ideas would be welcome. However, it should be noted this is 0.28 layer height temp tower from Orca Slicer.
Here’s the filament. I’ve heard of them which normally would have had me do an immediate calibration and test but for some reason, this one slipped through the cracks.
ooof. Wow.
I suspect from reading all your posts you’ve done all that can be done. Don’t kick yourself too hard, I’ve done the same thing, and eventually tossed it after cussing. A lot.
Makes you wonder why it’s currently unavailable.
Went to their website, same company name, they offer PEEK and beyond but no PLA-CF. They have a slew of engineering filaments so it’s a bit surprising they had a bum PLA.
1: I don’t use Orca Slicer
2: Why are you doing a temp tower at .28…??
I’ve done all mine at .2 & never had to re-adjust for .28.
Now, with all of that…
From your pic, the 1st layer…the hottest looks the best.
My guess, and it’s just a guess…this filament needs to be hotter.
Try printing a PETG or ASA tower.
I have 1 PETG that I had the same issues with, I used other colors so never bothered to read the label. Temp wasn’t the normal 220*-240* but 250*-270*.
Prints fine at 255*.
I agree with lion, think it wants to print hot maybe 220-240 range. How quick are you printing it and what accelerations are you using?
I found that filament on the Amazon uk site and the consensus among the reviews was hot and slow with low acceleration, it could be worth trying with speed around 60mm/s and acceleration around 1500mm/s to see if it makes a noticeable difference unless you have already tried this.
Edit: there also seems to be a large variation in quality between batches, I also found that on Amazon uk they had 2 variants of this filament one cheap than the other. Makes me wonder if they have replaced it?
Orca has baked-in calibration. Temp towers are 1 of 8 calibration utilities. Bambu does not have this.
Layer height shouldn’t impact the temp tower performance significantly and I did run one at 0.08 just to see if it would create any difference. It was far worse. Here’s what a temp tower in Orca will do. It changes the nozzle temp automatically for you at each section, something that if one loaded a manual temp tower they would have to painstakingly do by hand in the GCode
But I also ran one at at 220-260 at 0.7 which came out far worse.
I will try 0.20 and give it a shot.
I agree with that assessment and before I went to bed last night I ran an extended temp range(cited above) that was 220-260 at 0.08. Those results were far worse.
Accelerations were defaults but none of that should matter in a temp tower. Here are two examples of what I mean. The tall black is a PETG, the short black was PLA and the reddish is a silk I was experimenting with. All used default settings at 0.28.
I appreciate the research. Although acceleration should not impact this. I agree it is worth a try. I’ll run an experiment at high temp flows at 50% quiet mode and see if it has any impact.
Usually I would agree that acceleration wouldn’t cause this or have an effect but I found a few reviews saying otherwise. It’s definitely worth a try if it can save it from the junk pile. I had a filament a while back that didn’t seem to like anything over 7000 m/s but this was more to do with highly detailed areas were looking fuzzy.
I found people in the reviews complaining about quality from Batch 20221017ZD, might be worth checking against your batch number.
I’m happy to get a roll of each one and try it to see if the results I get are the same.
Do you own another printer besides the Bambu to print a tower on…??
When I was trying to print a PLA Wood tower on my A1 Mini after 4-5 tries I gave up. Printed 1st time on my SV06. So once I got the temp settings, I tried again with the A1 Mini.It came out better, but not as good as the SV06…I’m sure it was speed settings.
