Other Extruder Handling Considerations
The most common cause of failure is excessive movement and or rough handling of thermocouple wiring
and end connector. When assembling, avoid excessive forces on all wires and thermocouple. This is also
true when mounting an extruder back into the printer head for printing.
One way to avoid excessive wire movement is to secure Bowden Tube Adapter into place with set screw
exposed for easy access should a future service be required.

Set Screw Positions must be reachable, but as close to aluminum block as position will allow without
touching.
