please be patient as i am new to the 3d printing world
Having issues which i believe are an extrusion issue/s
its withe bambu white PLA MATTE
I have printed this exact profile before multiple times before with no issues
im not the creator, * Detailed description of the problem
its seems to be related to a new sppol of the white pla matte
yes i have dried it 50deg c 8hrs or so
AMS reads “A” for moisture
considering its only the white not the red or black
bambu P1s
Slicer settings used only thing i have changed is to remove the supports , ( printed a few of these before with NO ISSUES )
the only different thing i have changed, is changing to a hardened steel extruder and hot end ( both bambu store bought ) the black and red are new spool as well
here you can see a pic of the part printing
here is 2 of the final parts
1 is on a textured PEI plate the other is a smooth
can see what looks like colour bleeding through the white, yet the red is unaffected
Not 100% certain but I don’t think the white is dry. Matte filament can be a pita when it comes to moisture. Being new is no guarantee that the spool is dry.
Bump the drying temp to 55 and set it for around 12 hours. The current way the AMS displays moisture is far less accurate than it should be. The old way was much better, don’t know why they changed it.
If you set the hotend as hardened on the printers screen then it’s set within the slicer. If you look there will be an “Accessories” tab on the printers screen where you can change it to hardened nozzle if you haven’t. Really won’t make that big a difference. I use that setting for a Diamondback, but profile for the nozzle in the slicer. The system only needs to know to provide a warning when you use abrasive material.
Again, don’t assume new spools are dry, and don’t believe there’s a hard set time for the spools to dry. Just be patient and you’ll get it.
thanks, i find its strange as its PLA, not say PETG which absorb the moisture , i have a few PLA Mattes with no issues printing ( well some but i have them figure out )
Yes i have read and noted to dry filament regardless if its new
PLA can be the least affected of the “regular” filaments by moisture, well it can take longer.
Wait till you get to nylon. If you sneeze near it and droplets hit it, gotta dry again. (for those that don’t know sarcasm, that was it)
I used to love the Mattes. They can be weak in layer adhesion so be careful with that. They can produce some nice finishes though, I keep them around now for just that.
Hope you don’t run into any more problems. Happy printing.
cheers dude! i have some PLA CF and PETG CF i keep drying then throw into cereal box withe desiccant ( only have a 2 spool dryer ) , they seem to print fine
It looks like you might want to make the white a little more thick, or your filament is wet. Make sure you have a filament dryer, or manually dry your filament
not sure how i make the white thicker… the previous prints from a different spool are perfect , i have it drying over night around 50-55deg will try again later see if it helps, im in AUS and quite wintery currently , soi can get that it has absorbed some moisture, i just dont get why its only the white
Have you tried cleaning the plate? If you did, do it again. Use water and dish soap not IPA.
PLA isnt that hygroscopic as people might think, unless there are additives involved ( e.g Silk) What i would do, if youre not using BBL filament, would be to calibrate the flowrate ( maybe calibrate that specific white one) second, i would set the print with more layers of white before switching to black.
Why limit filament calibration to non-Bambu filaments? I have had to calibrate some Bambu PLAs because they did not print well. Bambu does not actually make the filament. There could be changes/variations from the supplier.
some of the reasons I bought the bambu was to introduce myself to 3d printing as it has the rfid and ams system and it just ( should just )works. so alot of the settings have been done by bambu.
I have been drying the white I’ll do the calibrationtonight and do another print again.
The only reason I hate calibrating Bambu filaments is because it basically creates a copy of that filament with a slight change, so it just populate the menu and sometimes you forget that you have a calibrated. If I could calibrate the original preset, I would do this for all the filaments.
So I agree calibration shouldn’t be limited to non-bambu filaments
Could be a little from A, little from B.
I’ve read all the replies and disagree with most. However, I’m just a guy who has a printer.
The first pic looks like it could be the plate. However the red is sticking well as does the black. Would be weird if only the spots where white is put down have adhesion issues. You can test this by using a different color. If it has problems then clean with the usual, but don’t dry with a cloth. Use paper towels. Washed items usually have fabric softener or detergent still on them, which can transfer to the bed. I’ve had great luck just using paper towels to dry, sometimes clean.
Calibration could be the culprit, but if you have had it print well before then wouldn’t be that.
If you have a different spool of white give it a try. If you’ve mentioned this than I missed it, sorry.
Investigating a bit more, try bumping the temp on that filament by 5. Print a test square of only 1 - 2 layers and see if that improves the problem. I wouldn’t bump it more than 10. Even filaments from the same vendor can be a bit different. If that doesn’t work then stop listening to me. Plenty of people will tell you I don’t know anything, ask my wife.
hahah thanks for the answer! im a bit with you actually, i dont dry the plate with anything, i either stick it on the bed and heat it , or put in front of the fire, im having issues with some PLA CF a mate said it could be due to the cold ( its quite cold here in AUS atm , so your idea of increasing the temp is one to try , as well as dropping the fan speed to slow the cooling down
ohh I DO have another roll of white to try! great idea! i have a small part that takes 30 mins to print of the same 3 colours, ill do that again, then its testing liek for like, ill try and do 2 of them on same plate with the 2 diff whites and settings
You could manually edit the original preset but you would lose the original. If you ever needed to go back to baseline you would have to reload software to get it back.
