Error	Cause	Solution
ERROR 211: USB removed	USB stick was disconnected during the print job.	Make sure that the USB stick has not been removed during the printing process. If the error occurs and the USB stick is still in the printer, 1. check your USB stick. 2. use a different USB stick.
ERROR 212: File not found	The printer is trying to resume a paused print, but the file cannot be found on the USB stick.	Restart the print job.
ERROR 213: USB Power Fault	The USB stick used draws too much power and has been disconnected so as not to damage the printer electronics.	Remove the USB stick; then click OK and try another USB stick.
ERROR 410: Setup file not found	During setup, the printer cannot find the file in the root directory of the USB stick or cannot open/read it.	1. make sure that the file wifi_config.cir is located in the root directory of the USB stick. 2. make sure that the file wifi_config.cir is not write-protected.
ERROR 411: Wifi connection impossible	WiFi connection timeout (probably because the router is not responding to the printer).	1. try to establish a connection again. 2. make sure that the WiFi router is working properly. 3. make sure that the firewall is not blocking the IP address of the printer.
ERROR 412: Wifi connection impossible	The password you entered is incorrect.	Make sure that the USB stick contains the file wifi_config.cir with the correct password for the selected network.
ERROR 413: Wifi connection impossible	The printer cannot find the network.	1. make sure that the USB stick contains the file wifi_config.cir with the correct network name. 2. make sure that the WiFi router is working properly. 3. make sure that the firewall is not blocking the IP address of the printer.
ERROR 417: Wifi connection lost	Wifi connection lost (timeout)	1. restart the Wifi transmission 2. check that the WiFi router is working properly. 3. try moving the printer closer to the router.
ERROR 520: Newer slicer required	The version of the slicer that generated the file is old and is not supported by the current firmware	Make sure that you are using the latest version of the slicer.
Other errors	An error has been detected that requires maintenance.	Try restarting the printer. If the problem persists, contact support (cubix@gebiom.com) and inform them of the error code.

• The filament was empty before printing could be completed. Check whether the filament needs to be replaced.
• Printer firmware error. Check the printer screen for error messages. If the error message is not self-explanatory, contact support.
• During the printing process, there was something in the work area that was blocking the printer. Check the work area for foreign objects.
• The silicone sleeve of the print head has fallen off and is blocking the printer. Check that the red silicone sleeve is correctly attached to the print head. Make sure that the silicone sleeve is not cracked.
• The power supply to the printer was interrupted during the printing process. Check whether the printer is switched on.

• The print surface is not clean. Wipe the print surface with isopropyl alcohol (see chapter 14).
• The print height is incorrect. Calibrate the height by following the print bed calibration (see chapter 8).

Cleaning the print head is an important process that contributes to the quality of the printed objects. It reduces the risk of clogging and ensures even extrusion of the filament.

Cleaning the nozzle from the outside

• We recommend that the outer tip of the print head (the nozzle) daily with the cleaning tool included in the accessory box.

Allow the print head to cool down first. Scrape the nozzle with the cleaning tool until the tip is free of filament residue. Make sure that you do not touch the inductive sensor (blue dot) behind the nozzle when cleaning it.

Cleaning the inside of the nozzle

• We recommend cleaning the inside of the nozzle every time a new filament spool is loaded. Only use approved cleaning filament for this process.

Proceed as follows:

1	Open the menu Filament changeby pressing the settings button (1).
2	Heating up. Please wait until the target temperature has been reached.
3	Pull the old filament out of the extruder and press the WfurtherButton (2).
4	Select Yes (1).
5	Heating up. Please wait until the target temperature has been reached.
6	Feed the cleaning filament into the extruder. When the filament comes out of the nozzle, press the Further-button (2)
7	In this automatic step, the temperature begins to drop as the material is extruded.   Note: You may hear a clicking sound. This is normal.
8	In this automatic step, the extrusion is switched off and the print head is cooled down.
9	Remove the extruded filament from under the nozzle.
10	Turn the lever to idle / position 0 (anti-clockwise).
11	Grasp the cleaning filament and pull it out of the extruder.
12	Clean any burnt residue from the nozzle using the brush supplied. Attention! The nozzle temperature is 110 degrees!
13	Look through the nozzle. You should be able to see through the hole.
14	Turn the lever clockwise to position 3 and then insert new filament.
15	Wait until the print head has heated up.
16	Insert the regular filament and when the material comes out of the nozzle, press the confirmation button (1) to complete the process.
