PREPARING TO PRINT
3. Hold the filament sensor and carefully rotate the spool while
the filament is unloading to avoid tangles.
4. IMPORTANT: When removing the end of the filament from
the sensor, carefully string the end through the hole in
the spool to avoid overlapping and tangles. These WILL
cause filament jams and failed prints.
Swapping Hotends
The Delta Pro’s hotend is easily swappable so you can print with
different materials at different temperatures. While we always
recommend using the default, PTFE-lined hotend for use with
PLA and many other low-temperature materials, the included all-
metal hotend allows you to print with materials which require
temperatures hotter than what PTFE can handle. As always,
please remember to use your printer in a well ventilated area.
Removing and Replacing a Hotend
1. Preheat the hotend and unload the filament.
2. Cool down the hotend, then turn off the machine.
3. Remove the Bowden tube from the effector by removing the
plastic pneumatic connector clips and depressing the top of
the connector while pulling the tube.
4. Disconnect the heater and thermistor connectors from the
cable harness.
5. While holding the hotend, use a 1.5 mm hex wrench (included)
to loosen the two headless hex screws on the side of the
heat sink below the effector, and the hotend should be easily
removable.
6. Replace the hotend in the same orientation and tighten the
screws.
7. Reconnect the heater, thermistor, and Bowden tube, ensuring
that the tube is pushed all the way in.
