The Kodak Portrait is meant to provide the user with easy access to the hotends for replacement.
For this reason both hotends are placed in a conical support that uses a screw to keep each of them fixed and centered in place.
Hotends have cables with simple connectors that allow the easy disconnection of them.
Hotend exchange is performed in 2 operations:
- Disconnect the connectors
- Unscrew the support until the hotend can be lowered down and removed. Do not detach the screw from the holder.
The holders must be handled with care taking into account that the screw must always be positioned and screwed in a linear direction movement to avoid aplying forces unto the thread.
If it were to be removed the screw needs to be inserted in proper alignment with the thread to avoid damaging it.
The hotend must always be positioned up to the top until the heatsink is in contact with the holder itself before performing the adjustment.
Example of a correctly positioned screw
If the screw is inserted incorrectly or over-adjusted it may lead to damaging the thread.
Example of a mispositioned screw
Once the thread is damaged the entire hotend holder needs to be replaced.
If the hotend can’t be replaced at the time a temporary fix can be installed until the hotend holder is replaced.
NOTE: This fix must be installed in both hotends.
