Creality K1, K1C, K1 Max, KE and K2: SimplyPrint Client or Klipper, and the camera

Creality K1, K1C, K1 Max, KE and K2: SimplyPrint Client or Klipper, and the camera


There are two ways to connect a Creality K1, K1C, K1 Max, K1 SE, Ender-3 V3 KE or K2 series printer to SimplyPrint: the SimplyPrint Client, or the Klipper setup on the printer itself. This guide explains the difference, which one to pick, and how the camera works with each.


In this guide


The two ways to connect


SimplyPrint Client

Klipper setup on the printer

What runs where

The Client runs on a computer, Raspberry Pi or server on the same network

SimplyPrint's Moonraker component runs on the printer

Changes to the printer

None

K1 series and KE: root firmware and the Helper Script over SSH. K2 series: turn on root access on the screen and run one command over SSH

Needs an always-on device

Yes

No

Creality CFS: map and sync slots

✓

✗

Print sliced 3MF files (.gcode.3mf)

✓ (not the K2 Plus)

✗

Baby stepping and Z-offset calibration

✗

✓


On the K2 series, the Klipper setup also has no time left, no layer progress and no print start options. The Client has all three.


Which one to pick

Pick the SimplyPrint Client if you can leave a device on. It is the one we recommend: nothing changes on the printer, and you get CFS syncing.


Pick the Klipper setup if you have no device to leave on, or you need baby stepping or Z-offset calibration from SimplyPrint. The Klipper setup is still offered for every printer in this guide, the Ender-3 V3 KE included; on the K1 series and the KE it needs rooted firmware first.


Connect with the SimplyPrint Client

  1. Install the SimplyPrint Client on a computer, Raspberry Pi or server on the same network as the printer.
  2. In the Client, choose Add printer > Creality.
  3. Pick your printer from the list the Client finds, or enter its IP address. The Client detects the model. There is no access code or password.
  4. Enter the setup code the Client shows in SimplyPrint.


Check: the printer shows as online in SimplyPrint.


The Client supports the K1, K1C, K1 Max, K1 SE, K2, K2 Pro, K2 Plus and Ender-3 V3 KE, and other Creality models such as the Hi.


Moving a printer from the Klipper setup to the Client

You keep the printer's name and print history in SimplyPrint.


  1. Remove the [simplyprint] section from the printer's moonraker.conf and restart Moonraker, so the Klipper setup stops connecting. On a K2 you can instead run the installer from the K2 setup guide again and choose Uninstall SimplyPrint. If you skip this step, Moonraker drops back to setup once the Client takes over the printer, and keeps showing a SimplyPrint Setup Request in Mainsail or Fluidd.
  2. Add the printer in the Client as above.
  3. In SimplyPrint, choose Link to existing instead of New printer, and pick the printer.


Check: the printer is online in SimplyPrint under its old name, with its print history.


Don't delete the printer in SimplyPrint first. Linking is what keeps its history.


The camera with the SimplyPrint Client

You do not install anything on the printer for the camera. The Client shows the stream the printer already serves. It looks for, in this order:


  1. Creality's own WebRTC camera stream.
  2. An MJPEG stream on port 8080.
  3. A go2rtc stream on port 1984.


The K1, K1C and K1 Max serve their camera at http://<printer-ip>:8080/?action=stream, which is not one of the addresses the Client looks for. On those printers you may need to enter it yourself.


If the camera does not show:


  1. Open the camera in Creality's own app or the printer's web page.
    • Check: the camera works there. If it doesn't, the printer serves no stream for the Client to show.
  3. Update the SimplyPrint Client, then restart it, or the device it runs on, and wait for the printer to come back online.
    • Check: the camera shows on the printer's page in SimplyPrint.
  5. On a K1, K1C or K1 Max: in the Client, open the printer's settings, enter http://<printer-ip>:8080/?action=stream under Custom webcam URL (use the printer's IP address), and save. When you add a new printer, the same field is under Advanced.
    • Check: the camera shows on the printer's page in SimplyPrint.
  7. If it still does not show, download the logs from the Client. Support needs them to look into it.


The camera with the Klipper setup

With the Klipper setup, SimplyPrint gets the camera from Moonraker. On a K1, K1C or K1 Max the camera usually works in the printer's own web page but not in SimplyPrint until Moonraker knows about it. See Creality K1 / K1C / K1 Max camera not working - how to fix.
