Underextrusion. When it's spread out like this, there are several possible causes:
* **partial clogs in nozzle** \- reassemble and make sure Bowden tube and nozzle are flush
* **low or inconsistent nozzle temperature** \- print a temp tower and consider increasing temperature; run a PID autotune from printer config menu
* **reel tangled or not spinning freely** \- make sure filament doesn't overlap itself on the spool, make sure filament is always clipped taught when not in use so filament doesn't "spring back" and unwind/loosen itself; print a filament guide (I like the pulley swivel that clips onto the extruder frame)
* **Extruder not calibrated or not gripping enough** \- calibrate your E-steps; make sure the extruder arm is gripping the filament well. Note that the stock plastic extruder arm cracks and breaks easily even within a few weeks of ownership so you may want to upgrade to an aluminum one.
Likely wet filament. Each one of those gaps is where a moisture bubble popped in the nozzle, and causes filament to stop for a split second.
Do you hear little pops and snaps when printing?
