First run with the InfinityFlow S1: things have gone badly. The PTFE tube at the hotend side isn't secured by anything but friction, so it popped off from the force the S1 is exerting.

And it looks like they sent me the wrong adapter, so I'm going to have to unload everything, print that, and put it all back together.

BTW you can load filament into the #Flashforge #AD5M without top access, but it's very awkward. #3DPrinting
