I can happily print lots of different models from easy to semi complex mostly without fault on there own but when trying to just print two at the same time with spaces all hell brakes loose.
I wanted to print 4 corner pieces which I had already printed them before but separately without fault but when I put 4 of them into Orcaslicer or Bambu Studio and spaced them out (also set them to print by object order) they always mess up.
The last time (print by order) showed no errors before printing but about 20% of the way through about 40g of material just went all over the place. I tried again but without print by order and again, failed.
I tried with just two objects but again, all messed up. Any ideas?
As I mentioned, I can print pretty much anything but only one of them, as soon as I add more than one so I dont have to take the model out etc it ALWAYS messes up.
Settings are pretty much stock and have tried using PLA, PLA+ an PEG-T.
Erm, I think the fan was just default if there is such a thing? Only the one filament and colour PLA Basic Black.This happened ages ago also when using PLA + and these are the only two times I have tried to print more than more item at once.
Im just about to print something else small so can try doing to of them also with some suggested settings?
Can you share your stl, or better yet, save it as a project and share that? I can give it a go on my printers and at least we can eliminate some variables.
Wait…what? I had some issues with curling at the part edges from the bed and narrowed it down to the Aux fan. Now I run all of my PLA prints with the Aux fan turned off for PLA, especially Bambu PLA. This comment genuinely shocked me a bit. I’m not going to change anything if I’m getting good prints, but I would like to understand the nuances of using the Aux fan between this guidance and what I saw earlier (found a long list of ppl saying to cut the Aux fan).
P.S. I came to this page because I printed a little magnet holder that came out great. When I tried to run multiples (printed by layer) I got some curling on the parts again (Aux fan is still off). So I ran them by object, but I need to print a few more and I wanted to understand what settings I could tweak to improve multiple parts. This isn’t a retraction issue, I had originally thought it was a “minimum layer time” or some other setting that would improve this.
I’m creeping up on the 6000 hour mark on my X1C and still run my Aux fan at 100% for PLA
In addition I have no cooling for the first 3 layers and run slower speeds for the first 10 layers which slowly ramps the print speeds up until the tenth layer is reached
Curling on the edges is typically an adhesion issue, curling on the edges further along in the print is likely due to part cooling which is a combination of fan speeds and print speeds
That all being what it is if what you are doing works then by all means keep doing what you are doing
I just know what works best for me and can only offer advice on my personal experience with the intentions of helping others tgat may be having issues
