Ender 5 Underextruding
If you pulled the Bowden tube out of the hotend and then got this, you almost surely installed it wrong, leaving a gap between the tube and the nozzle for molten filament to fill and jam in. Remove it again with the hotend hot, and if there's a mess inside, look for guides on cleaning it. Then, to reassemble, loosen the fitting from the heat sink by 3/4 to one full turn, press the tube in as far as it will go, then tighten the fitting down to compress the tube against the nozzle.
