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 that the inside of the nozzle twice a week or every time a new filament spool is inserted. Only use approved cleaning filament and the "cold pull" method described below.

1. Remove the inserted filament from the nozzle (using the filament change procedure)
2. Insert the cleaning filament into the nozzle.
3. Extrude 3-4 cm of filament. In some cases, the clogged material will come out.
4. Set the temperature so that it drops from the standard setting of 265 °C to 125 °C.
5. Extrude the cleaning filament while the temperature drops.
6. Extrusion stops at around 200 °C because the filament can no longer melt.
7. When the temperature has reached 130-125 °C, pull the cleaning filament straight up out of the hotend until it emerges from the nozzle.
8. This strong pull removes impurities and material from the nozzle.
9. Look through the nozzle hole, you should be able to see all the way through.

If this is not the case, repeat steps 2 to 9 until the cleaning filament can be removed free of impurities and you can see through the nozzle opening.

• The outside of the print head (nozzle) should be cleaned daily. Use a plastic or wooden tool to avoid damaging the brass nozzle tip in the area of the filament outlet hole. Scrape off the filament until the tip is free of filament residue.
• The inside of the print head should be cleaned regularly to ensure even extrusion of the filament. Clean the inside of the nozzle as often as filament is changed. Only use approved cleaning filament and its procedure.

To ensure that the printer continues to print as expected, regular cleaning is recommended. Both the print bed and the print head must be cleaned.

System information about the printer can be found in the information menu. This is usually used for customer support.

If required, it is possible to control the movement and heating of the printer manually.

Printing via WLAN is started directly from the GP Inlay Print module in the GP Manager and the file is automatically transferred to the printer's internal memory.

	Open the GP Inlay Print module and select the relevant job from the job list. Select a page. Check whether a printer in the printer list on the left-hand side is idle (IDLE). Make sure that the printer is prepared for printing. See chapter 10. Start printing using the button Start printing via WiFi. The printer indicates that printing is being started via Wi-Fi.
2	The print preview screen shows the status of the print process during printing: (1) indicates whether the printer is currently heating or printing. (2) displays the current and target temperature. (3) shows the remaining time of the print job to be completed. (4) indicates whether printing has been started via WiFi. (5) shows the progress of printing in %. (7) displays the file name of the object to be printed.   To pause printing, press the pause button (8). Further information can be found in section 11.3.   To cancel the printing process, press the cancel button (6).
