Yeah same set. What can you expect? Two things that’s it.
Might have less runout. My example does but who knows if it’s a good, bar or average. Same with my stock gears I don’t know if they are good bar or average. I got other sets but I don’t feel like checking them.
Reduced backlash. Could help with extrusion quality. The reduction In backlash combined with less runout. But since we don’t have specs I wouldn’t count on this. Without specs you could get something significantly worse then what you already have…Then again Bambu has no specs so you could get something that is significantly better. No one knows.
Just try it out. Best case you see some improvement or even if you dont it doesn’t really hurt anything if you seen no change or worse case you get them you get some weird artifacts in your print and you wasted $12 and 15 years of your life waiting for the. To get there from AliExpress.
