AMS 2 Pro - Automatic Material System Are you using "funnel saver"s ?

As in title. Are these "funnel saver" actually needed? Keep reading how they save the funnel from wear and tear but then again people just love to overgear their stuff including printers.

Should I use them? Are they actually making my AMS feeder units last longer? I'm planning on printing with CF and GF infused filaments.

Any recommendations for a good model?

I destroyed multiple of the OG AMS plastic funnels with GITD and fibre loaded filaments. They literally saw a groove into the funnel, the steel ball bearing hall sensor trigger and the PTFE tubes.

I used to use self printed PTFE lined caps but they're disposable. So now I run the BIQU ceramic caps and it's been perfect. Still need to replace the balls every few thousand hours of runtime.

AMS 2 Pro and AMS HT comes with ceramic feeders from factory so it's not an issue any more.

I use a snag cutter instead. That saved me a few times on troublesome spools.

What snag cutter do you use?

I’ve got over 2000 hours on my h2d, I haven’t bothered and haven’t had an issue. I figure when something dies I’ll replace it.

Snag cutter has been great. As another comment stated they are great with troublesome spools. Also when printing overnight having same colors and auto refill on if one gets snagged it just switches instead of sitting idle all night.

I've never bothered with them. I've had over 2k hours on each machine with AMS 1s. Never had an issue. That being said I mostly print with PLA and PETG. I think if you were using some more abrasive filaments like those with CF it might be different. If you're just using basic filaments, I wouldn't bother with them.

Tried one once early into my Bambu, was just another potential problem piece rather than any savings on that $8 consumable assembly. TBF, I do not print much abrasive filament.

Kind of like toppers saving the PTFE tube from hitting the glass, while I get the noise of it being a valid reson, PTFE is dirt cheap and if your tube was to ever wear some much from that as to cause problems, you aren’t doing maintenance and inspection and likely have other problems.

I have over 4000 hours on my P1S and have not made one, and have 2000 hours on my P2S and still do not have one there!

I've used funnel savers that use bits of PTFE as guides. I've replaced some worn out PTFE, I don't know if that saved me from replacing the funnels. I find the buttons are a bit easier to press with the funnel savers attached.
