Not possible to print Bambu PLA Glow on A1 Mini

My three weeks old Bambu A1 Mini + AMS Lite prints with Bambu PLA Basic filament in good quality.

Now I have purchased Bambu PLA Glow filament and after trying for 5 hours I have given up. It seems this printer cannot print with this filament.

The printing starts fine, but after about a minute the extruder stops printing goes to the side and waits for new filament to flow. Then it tries to cut the excess filament, but because this filament is very “sticky” it fails at cutting it correctly with a rate of about 90%. The filament still hangs on the nozzle head and the printer continues printing. It then either drops on the printing bed, or directly on the object ruining the print. After about 10-40 seconds the printer goes again to the side in order to wait for new filament to come in. Rinse, repeat in a loop of short printing, going to the side, waiting for filament, trying to cut it, failing, dropping on the printing bed while printing for another 10 to 40 seconds. The attached picture says it all.

I’ve got a tip to place a 1cm PTFE tube piece on the cutting tray from here:

With that small modification about 50-60% of the filament strips land in the bin, instead of only 10% without this modification. But 50% it’s not enough, as it’s extremely frustrating to print anything with this (expensive) filament.

I’ve also tried cheap Amazon Basic PLA glow filament and it prints without problems.

I take, you’ve read these…??

Yes, but it says not recommended, but not impossible.

I used some PolyMaker glow filament via the AMS Lite, and probably won’t ever do it again. It definitely had feed issues, enough that I could feel the difference when pushing it through the tube by hand. I didn’t have as bad of issues as you did, but I did have to fix feed issues during a print a couple times.

Is it just the tube that’s the problem? Could I hang the spool off the back, remove one of the AMS tubes from the filament hub and feed the pla-glow directly into the hub? Or will the hub also have issues with the pla-glow?

Also noticing that the pla-glow is not a filament option in Bambu Studio. Is there an update coming for that? just curious.

I think it’s a matter of length of the tube, tightness of bends, plus potential friction in the AMS feeder itself?
You should have an external spool holder along with its tube, try using that tube (it’s shorter).
Not sure I’d do it without the tube entirely. That is the way Bambu recommends using non-AMS compatilble filaments.
PLA Glow should run fine with the standard PLA settings.

If you only need to use one color this worked for me:

If you notice it says AMS Not recommended as lion7718 mentioned above and as Sharky04 mentioned as well. So why not bypass AMS lite all together? This is what SonOfAnakin had suggested and I can tell you, this for sure works.

What worked for me is I removed 1 tube from the “AMS Lite Filament hub” (pictured below)

Hung the roll of filament above the A1 mini as mine is in a closet (make sure it is complete direct not touching anything between the roll and the AMS lite filament hub) , this created a direct feed bypassing the any tube resistance and my prints went off without a hitch, it even let me use the preset for the glow filament without a fuss in the software. (as it seems an update warns you the glow is not recommended or compatible)

For extra safety you could remove all of the tubes and tie off to the side, for extra extra you could move the whole AMS lite away from the printer. ( was right there for my prints so I could keep an eye on them.

If anyone is interested in printing with TPU (TPU 90a), this is exactly how I did that as well.

I may also note that I needed to dry some of the glow filament before use(40 Celsius for 6 hours) as it was very stringy gave me underfilling and under extrusion issues, this also greatly improved my poops :wink:

Hope this helps, enjoy!

Thank you for this! Buying some glow filament now!

Happy printing! Would love to see some results :slight_smile:

Hey there, I’m having the same issue with printing PLA Glow with the A1 Mini. The main problem is that there is NO PLA GLOW SETTING when printing with the A1 Mini. Nowhere on the website does it say PLA glow is not compatible with the A1 Mini, so I’m so confused about how I can get it to print. Does anyone have any ideas as to what is going on here?

Two things.

  1. PLA Glow is not compatible with the AMS lite.

  2. You need to add PLA Glow into your library of filaments you wish to see when selecting filaments. Edit the available list and tick the appropriate glow options.

Cheers for the swift response!

I am not using the AMS lite, so I am using an external spool. And this case, when I manually try to select the type of filament loaded, there is no option to select PLA Glow?

Maybe you don’t have it enabled as a filament choice? Needs do be ticked here (I don’t have it ticked as I don’t have any yet).

Yh, i made sure of that and there is no selection for it on the app, nor the printer for some reason

Ouch, yeah, I see that now… can pick it on the A1, but not the A1 Mini :cry:
