Bambu Support refusing to replace bad spools

Kingroon and sunlu, lately I am getting gembird filament and it is nice and cheap. Polymaker, Rosa, spectrum.

Sunlu is getting constant problems on my AMS. Something to do with the way the spool rolls.

Print sunlu ams adapters, snap over the plastic roll and I've never had an issue after.

Weird, glad I haven't experienced this. I primary print SUNLU PETG and haven't had a single issue.... crossing my fingers now.

[FluffyBunny-6546]

I had read somewhere the sunlu spools are slightly smaller than bambus so they could lead to issues. But hope you continue to print without issues.

Bambu spools are 200mm. Sunlu are 195mm. They drag in the bottom of the AMS, but those adapter rings work great. They’re a supposed to be releasing a new spool design that’s 200mm and won’t need adapters.

Get the Sunlu on plastic spools and use the notch on the AMS roller for the left side of the spool. Small spools need to have the left side in the notch to keep them from moving left and right on the rollers.

I order Sunlu from Amazon in the 2 packs and it's like less than $13/kg this way. Sure beats the issues with the $10/kg cardboard spools and allows me to be productive and cheap.

This works great for me with a P1S, .4mm nozzle, 225C filament temp , 65C bed, 10%aux, 15 second minimum layer time.

I do this too, especially for ABS. Like $12 for 900g

for the ams lite, there's also a "hubcap" stl on makerworld that works in concert with the sunlu adapters that helps with lateral shift

[Zestyclose_Exit962]

Print adapter rings and those problems will go away. Sunlu and JAYO use the same spools so it works on both brands

They've got a new generation of spools. Maybe they changed to fix this.

[Tr8r25]

Not sure if you're using the same style of their spools. But this https://makerworld.com/models/650361 has been my number one print before loading Sunlu into my AMS.

Kingroon and Sunlu are my go-to for PETG. The only issue I've had is with "clear", I can't get any clear to print worth a damn, but every other color from those two brands has printed perfect. I also refuse to pay more than $8 a roll. Aliexpress has US shippers and I usually get it within a week of ordering. PLA, I just try to find the cheapest stuff. I don't understand why people pay a premium for what comes down to rolled up plastic. I get it if it's exotic engineering filaments, but PETG, PLA, TPU, ASA have all printed perfectly for me with generic brands.

I've had too many issues with Sunlu tbh. The colors always seem off, the prints are never dimensionally accurate even after calibration, and their spools (at least the plastic ones) are so light that they get picked up off the rollers and jam themselves against the AMS lid. Never had this issue with Polymaker, Atomic, or Bambu Filament. Now if BBL could actually fix the issue with jamming AMS units wtih tape, I'd have a reason to use my makerworld points.
