Creality 3D printer troubleshooting
19 guides to fix Creality 3D printers: the symptom, the likely causes, how to check which one is yours and the step-by-step fix, with official sources from Creality.
Printers covered: K1, K1 Max, K1C, Ender 3 V3 SE, K1 SE, K2 Plus, Ender 3 V3 KE, K2, K2 Pro, Ender 3 S1 Pro, Ender 3 V3, Ender 3 V3 Plus and 15 more.
Each guide summarises the official documentation and says whether usi3d has already verified it on a machine.
Adhesion and first layer (3 guides)
- K2 Plus: a clump or blob of filament forms around the hotend
On the K2 Plus filament builds up around the nozzle and hotend into a lump that can wrap the nozzle cover, the fans, the nozzle camera or the hotend board.
- The K1 levels badly: the nozzle scrapes the bed in some areas and the layer is too high in others
On the K1, K1C or K1 Max the first layer is not the same across the plate: in some areas the nozzle scrapes the surface and in others the line is too high or does not…
- The K1 pauses itself due to AI detection (101, 103, 104) or warns about the LiDAR (505, 506, 507, «LiDAR not detected»)
The K1 series printer stops printing with an AI detection warning: 101 (spaghetti detected), 103 (first layer problem) or 104 (foreign object on the bed), sometimes even…
Extrusion (5 guides)
- CFS: what its lights mean and what to do if the printer does not detect it
The slot lights on the CFS (Creality's multi-colour system) flash or stay red, or the CFS turns its screen on and pre-feeds filament but the printer does not detect it.
- Ender 3 V3 SE or KE: no filament comes out, the nozzle clogs or the extruder clicks
On the Ender 3 V3 SE or Ender 3 V3 KE no filament comes out of the nozzle, the filament cannot be retracted, the extruder clicks while printing or its gear does not turn…
- K2 Plus: the waste chute clogs and the purge does not fall out (sometimes with error 2060)
The purge waste the nozzle ejects when changing filament or starting a print piles up in the waste chute and does not come out.
- The K1 is not extruding: the gear spins or clicks (jam in the extruder or hotend)
On the K1, K1C or K1 Max no plastic comes out of the nozzle even though the extruder gear turns, sometimes with knocking or clicking.
- The K2 Plus CFS will not load or retract filament (codes FR2833, FR2836, FB2847…)
With the CFS (the multi-material system) the K2 Plus stops when loading, retracting or changing colour and shows a code starting with F, for example FR2833 (feed issue)…
Print quality (1 guide)
- Ender 3 V3 KE: the vibration sensor is not recognised, the screen flickers or ringing appears (input shaping)
When you connect the vibration compensation sensor (G-sensor) to the Ender 3 V3 KE for input shaping, the screen says no sensor is recognised or starts flickering; or…
Mechanics (3 guides)
- Ender 3 S1 Pro or Ender 5 S1: first layer too high or scraping after levelling (CR Touch and Z offset)
After automatic levelling, the first layer does not stick because the nozzle is too high, or it scrapes the plate because it is too low; sometimes one corner differs…
- Ender 3 V3 SE or KE: leveling fails, CR Touch error or the nozzle scratches the bed
On the Ender 3 V3 SE or KE automatic leveling stops with an error (leveling failure, CR Touch error or height measurement failure), the nozzle keeps probing the lower…
- Ender 3 V3 SE: noise or stuttering on the X or Y axis, from a motor or from a fan
The Ender 3 V3 SE makes an odd noise when the X or Y axis moves, a motor makes noise while printing, an axis stutters at one spot (sometimes with a noise) or a fan does…
Electronics (4 guides)
- Ender 3 V3 or V3 Plus: the hotend does not heat (error 2564 or 111) or it restarts while heating
The Ender 3 V3 or V3 Plus shows «Error, key: 2564, the extruder is not heating as expected», gives error 111 at start-up or while printing (communication between the…
- Ender 3 V3 SE: nozzle or bed temperature too low or too high, or it restarts while heating
The Ender 3 V3 SE reports that the nozzle or bed temperature is too low (it does not reach the set temperature in time) or too high (usually right after switching on)…
- Ender 3 V3 SE: the Z axis does not move when homing, the gantry is crooked or the nozzle height is wrong
On the Ender 3 V3 SE, when you press «Home» the Z axis does not move up or down, the gantry leans backwards (towards the Z motor side) or, after the height measurement…
- The K1 shows a «key» error for the print head or bed (2000, 2001, 3002, 2564, 2565)
The K1, K1C or K1 Max screen shows an «Error, key: …» window and the printer stops or does not finish booting.
Connectivity and firmware (3 guides)
- Creality Print or Creality Cloud will not send the print (Upload Failed, Send Failed) or the printer shows offline
When sending a job from Creality Print over the local network or the Internet you get «Upload Failed» or «Send Failed» with a number in brackets (7, 9, 25, 26, 28, 55…
- K1: update not found, update fails or it stays on the start screen (memory full)
On a K1 series printer, the online (OTA) update says «You are currently on the latest version» even though a newer one exists, the update fails, or the printer stays on…
- The K2, K2 Pro or K2 Plus will not connect to Wi-Fi, sees no networks or keeps disconnecting
The K2 series printer finds no Wi-Fi networks, sees networks but cannot connect even with the right password, or connects with a weak signal and drops out often.
