Look at my print and tell me what's wrong :)

well it's clearlt under extrusion.

Could be many things, but with a longish bowden tube, it might simply be the extruder is struggling to push the filament through. At a certain height the angle of the tube changes and it suddenly starts getting through a lot easier.

Could have also been a dodgy patch of filament - but my money is on it just not beiung able to push enough filament through the tube - did you hear any 'clicking' during the print ?

Depending on what type extruder it is - sometimes you can tighten them up so they push through any tight spots.

Regardless of this print - converting the machine to a direct drive extruder would be the first thing I'd do.
Hell I'd have dne it during the construction.
There is no logical reason for the ender 5 to use a bowden extruder other than laziness on creality's part.

Thanks! I retried the print with just adjusting my bowden tube, giving it a few strips close to the extruder to make it straight(er), and next one came out pretty perfect.

On the topic of direct drive, anything specific you'd recommend for the Ender 5 Pro?

Depends on your budget really. Cheapest solution would be to take the existing extruder and use it. That's a pretty ugly and heavy solution though.

I prefer getting a small pancake motor, a geared extruder (like a BMG or Titan), and a hotend that is designed to match up with that extruder. That can get pricey fast though.

With regard to the bowden, the issue you found in your print can occur because the bowden isn't seated properly at one end (as you may have found with the adjustment). What often happens is that a bit of wear occurs and the bowden can move back and forth. This stuffs up your retraction distance, and you'll often get a lag when starting extrusion. First thing I'd check if this sort of problem happens again is that the bowden is firmly seated at both ends, with no gap between the bowden and the hotend, and no movement at either connector.
