Blobbing on outside walls Bambu PETG Basic, drying issue?
  • I also figured out, I can adjust the max volumetric speed of the PETG filament settings and that will limit the wall speeds autumatically

    Edit: This turned out to interact weirdly with layer height changes, I ended up just reducing the max speeds.

  • It's kinda not at the start or end of the layer. The layer starts with the inner wall, which prints fine and then it does the outer wall which doesn't do fine.

    Which corresponds to the wall here

    What slicer are you using?

    Bambu Studio 1.8.4.51

  • Thanks for the input!
    So the thing I was trying to print was this: https://www.thingiverse.com/thing:6365845
    Ideally you'd just print it in PLA but I only had one colour PLA so I thought, might as well gather some PETG printing experience :D
    The part in question is red_panda_low_poly_V1_-_head_A_red.STL and I tried to print it on an odd angle to make sure that most of the outwards facing walls were on the top, because anything that needed support turned out so hideous.

    Also it seems to appear on any side of the model, where you have a slight overhanging angle, in no particular axis :)

    I'll print it in pla once my current print is done :D

  • I tried to observe it but it just goes straight over it.. It seems a bit like a cascading issue, where one layer has a bit missing and then the next one blobs onto the next because it's trying to print on nothing, idk

    It also sometimes catches itself again and you get these patches of weirdness and then it's okay again

    Edit: Setting the max speed for walls to 50 mm/s solved it! I feel like this should be limited when you select the filament, but oh well.

    Hey, so I have recently gotten a Bambu A1 and got a roll of PLA and PETG. The PLA is printing very nicely out of the box but the PETG not so much. Since I'm still very much at the beginning of my 3D printing journey, I don't really have a good way of drying my PETG yet, I just stuffed it in a plastic ziplock bag with all the desiccant bags I got from the rolls and printer and stored it that way. I'm already planning to print myself a filament enclosure, I just haven't gotten around to buying the bearings, etc for it.

    I've done some functional prints with no angled (overhanging) walls and they have turned out pretty good. When printing on supports the overhangs are ugly af, but no weird pattern like this.

    The issue I'm tracking down seems to occur on ~60+° overhangs, that really shouldn't be an issue. I've done a sliced test print and took some photos, any idea what causes this? Thanks :)

    Bambu A1, standard 0.4mm nozzle Bambu PETG Basic filament and profile using Bambu Studio Some settings I played around with was flow rate (0.94->0.95) and layer height (0.2mm -> 0.15mm) but it seems to make no difference.

    (note, on some of them the part is photographed upside down.) ! ! ! ! ! !

    8 Years later my Steam Link is still getting regular updates
  • I thought this too, but unfortunately in terms of modding and general use they are very limited, afaik. When I looked into it, it boiled down to: There's an sdk to develop stuff for it and you can get root access but good luck trying to replace the os or anything like that. That being said, this is what I remember from ~2 years ago, so if it can be customised more now, please let me know. I kinda bought 2 in hopes of being able to do that :D

  • Hey, not sure how in depth your linux/docker knowledge is. Please disregard if irrelevant. I would recommend you pick a fixed mountpoint for the drive and set up a systemd service to mount the drive for you (systemd .mount file). Then you add an extra line "RequiredBy=docker.service" (look for systemd RequiredBy) This way the drive always has to be mounted by the system before docker is started and should always be visible before you start a container.

    Hope this helps :)
