4.3. USING 1.75MM FILAMENT
clean by wiping it with Isopropyl Alcohol and by lightly sanding the PEI
surface with 2000-2500 grit sand paper.
4.3 Using 1.75mm filament
The Mini 3D printer is set up to use 3mm plastic filament by default.
Although we recommend using 3mm filament, the Mini is also capable of
printing 1.75mm filament. To print with 1.75mm filament you will need to
purchase a 1.75mm compatible Hexagon hot end or any other compatible
hot end.
To change out the hot end:
1. Remove the plastic filament from the extruder if there is any currently
loaded by bringing the hot end up to extrusion temp and pulling out
the filament.
2. Using the printer host software’s manual controls, raise the Z axis to
150mm.
3. Turn off all power to the printer and allow the hot end to cool.
Disconnect the hot end and extruder connectors on the extruder
assembly.
4. Using a 3mm hex driver loosen and remove the two 4mm screws from
the bottom of the extruder X axis carriage. This will allow you to
lift the extruder body and hot end off of the extruder mount. Set the
extruder body aside.
5. Place the new 1.75mm compatible hot end back onto the extruder
mount. Make sure the wires are facing the rear of the printer
6. Place the extruder body back on top of the hot end and extruder
mount. Line up the two mounting holes. Push the two 4mm screws
through the bottom of the X carriage, through the hot end, and into
the extruder body. Thread the screws using the 3mm hex driver but
leave them loose for now.
7. Reconnect the hot end and extruder connectors.
8. Finally, push 1.75mm filament through the extruder and into the hot
end. This will align the filament travel path. Tighten the two 4mm
screws from the bottom of the X axis carriage.
