 Make sure that the nozzle and hot-end are cleaned when loaded with plastic residues. To clean of the nozzle, simply heat it until the plastic gets sticky, and use a printed cube to peel of the sticky plastic. Make sure that the nozzle and hot-end are cleaned when loaded with plastic residues.

 +==== Clean drive gear ====
 +The drive gear is not designed for serviceability, but with these steps it is not too painful.
 +  * **Connect Tripodmaker** to Repetier-Host using the 2 usb extension cables.
 +    * Connect the USB cable **to the Renkforce USB Hub**. //Don't connect directly to the back of the iMac. For some reason only the USB hub connection works.//
 +    * In Repetier-Host, set the printer settings:
 +      * **Port**: look for the 'usbmodem' entry (or look for the change in the port listing when plugging in the cable).
 +      * **Baud Rate**: 115200
 +      * **Stop Bits**: 1
 +      * **Parity**: None
 +      * **Transfer Protocol**: Auto
 +      * **Receive Cache Size**: 63
 +      * **Timeout**: 40s
 +      * **Use ping pong communication**: not ticked
 +      * **Firmware sends OK after error**: not ticked
 +    * Click 'Home All' to test the connection.
 +    * **Heat up the extruder** to 180°C. This is approx the lowest temperature needed to be able to turn the extruder motor. Colder, and the software gives a warning to avoid cold extrusion.
 +  * **Clean** the drive gear slots you can reach with a sharp pick. Insert the pick just in front of the idle bearing. Be patient and do one slot of the gear at a time. Only ±4 slots are in reach.
 +  * In the print panel of Repetier-Host, **extrude ''2,5''mm** (the speed is not important). This rotates the extruder gear just enough to clean the next section
 +  * Keep cleaning until the whole gear is free from plastic.
