Many thanks. I appreciate the info shared. 100C is enough. My current and only issue relates to the air temperature, the reason why I want to make my own. I’m in the EU, so it may be harder to find exactly some components. But a similar heater is now on my part list.

I dried longer and it got a little better. I believe my 0.4mm nozzle may have cracked or something I bought a replacement 0.4mm nozzle (thought I had a spare on hand… I did not) that came in the mail today, but when I switched to the 0.2mm nozzle for a print the issue went completely away on my prints. Drying made it better but didn’t completely eliminate the issue. Swapping in the 0,4mm nozzle tonight and will see how it works.

And back to issues… the 0.2 did not have any issues, but same roll of filament and I switch back to a new 0.4 and it is doing it again…
Was just discussing water issues in general with another user and had a thought. My old printer didn’t seem to mind moisture content. Never dried filament and the only real effect was when it got too brittle. That printer was pretty slow compared to the Bambu.
I think water issues in general may be provoked by how fast these things print. Filament feed rates are higher. With a smaller nozzle, though, your feed rate will drop. I really have to wonder if there isn’t enough time for more water to evaporate before the filament enters the melt chamber proper and that is why moisture is seemingly a bigger issue?
That could be possible. idk… I have never had water issues and this filament isn’t brittle. I have had other filament be brittle and it ran through just fine. for some reason the black that I recently bought has just had a ton of issues. I just ordered more and it came in yesterday. I need to test a new roll and see what happens, and I guess try some other colors… I print a ton of black filament.
Brittle filament is kind of the last thing that happens on moisture road I think. Print defects seem to come before that.
No idea since it has been a while, but there was a batch of black Bambu PLA that caused all sorts of print issues. I looked back to see if that’s what you were using but didn’t see it. If it is, if it’s really shiny filament, it could be the same. Inventories can take a while to clear and after that batch hit I bet many didn’t order it so inventory may still be out there.

I’m not saying your issues are from water, though. I was just saying your 0.2 and 0.4 experiment fits with the observations so far. But no proof it’s actually water.
yeah it is black Bambu PLA. Had issues with the cardboard rolls fitting the spools and these print issues with the latest PLA I have gotten from them. I bought this filament about a month ago. and just bought more this week.
Can’t say for certain, but I believe the problematic filament had those issues too and I think a big wad of tape holding the filament to the cardboard hub.
You might want to talk with customer service. If you have the serial number of the spools they can tell you. Might also look at the threads here on tape at the end of the spool and another thread where a user was printing a life size iron man and noticed and posted about the changes to the Bambu white PLA - it had the same issues.
yep won’t auto swap spools once out bc of the tape. I have ben having that issue.

I created a support ticket… Guess I need to break out the new filament I just bought and see if it is any good… Just bought another 8 rolls of Bambu Black basic PLA…

Well new batch of filament does not have the same issues. Is running great. Guess I am getting rid of any of that old batch I have left, and will deal with the rest through support… If I ever get a response.
Wet filament klaxon!! I often find some of my printers are more sensitive to wet filament. My creator pro 2 for instance, it doesn’t mind filament that’s been on the back of it for months, still does the job. Prusa mini+ is very sensitive and almost always needs filament in a dry box or it will start stringing regardless of slicer settings.
X1C, now here is the issue. Historically I have found it to deal with damp PLA very well. The biggest issue for me is how well it deals with it can also be down to a firmware update. I’ve never known prints change quality so much (good and bad) through firmware updates than with these machines. This is what frustrates me most I think, their updates always add another variable, another doubt in your mind, whereas Flashforge and Prusa I feel way more comfortable that the issue isn’t caused by the latest update.
I have used months sitting out filament without issues until this batch of black PLA. I dried it also multiple times. tried the recommended 8 hours in a filament dryer. No good. then tried 24 hours and still no change. Got a new batch and it run perfectly fine without drying at all…
I have many sliced designs on SD card from last year that use the default 10% ironing flow. An update somewhere down the line made these files all useless as the ironing flow algorithm seemed to change, and now the same prints need 18-20% for a nice finish ¯_(ツ)_/¯
