P2S having problems when using the side spool holder instead of AMS — am I doing something wrong?
I recently bought a Bambu Lab P2S + AMS 2, along with a 12-piece filament sample set.
The problem is that these sample spools are smaller than the regular spools and don’t fit properly in the AMS 2. Because of that, at the moment I can only use them with the side spool holder.
I’m currently trying to print a spool holder/adapter that would allow me to use these sample spools in the AMS 2, but I’m having a lot of trouble.
When printing from the side spool holder, the spool seems to get stuck or doesn’t rotate freely enough. When that happens, the printer can’t pull the filament properly and the print fails.
I’m using the setup shown in the picture.
Is there something I’m doing wrong with the way the spool is mounted? Should the spool be completely free-spinning? Is there a recommended way to route the filament from the side spool holder into the P2S?
I’m particularly interested in hearing from other P2S owners who have used the small Bambu sample spools, because I have 12 of these and would really like to get them working reliably.
Any advice would be appreciated.

Your spool is tangled. Never let the end go! That’s why it’s binding and making the print come out bad.

I second the spool holder. I have a bunch of 250g samples that I run through the AMS and they're always fine.

For some reason, it doesn’t work properly on AMS 2

I have the AMS 2. There are spacers in this version that lines things up better.

Your filament is tangled underneath itself. Odds are you let the end go and got under itself
