I tried exactly what you said in your video, and I actually got two decent results. But now it seems like the filament isn't coming out. It'll go through the motions of the print, but nothing will extrude out. I tried pulling the build plate down to see if it was too close, but it didn't make a difference. The weird thing is that I can manually extrude the filament out so I know there's nothing stuck.
Any suggestions at all are appreciated.
In general the closer to the bed, the better filament sticks. If it gets so close that you can barely see the "trace" then it sticks a bit too well and you might break the glass getting it off. Every filament is different in how well it sticks but more squish always means it will stick better.
You can verify this while it is printing the first layer. Push up a bit on the bed if it's not sticking at all.
I don't know XF-CF20 - I assume CF20 means 20% carbon fill. There are about 5 key things to get filament to stick. One is to clean any oils off the glass (e.g. from fingers). One is to add certain types of glue. One is to get the right temperature. I describe how to get the right temperature, why it matters, and other tricks in this video:
