Composer A4 uses three coils: two of them are common 3D printing filament plastics, and the third one is Anisoprint Fiber.
To load or unload a material you need to press Maintenance > Materials and choose a material coil you want to operate with. Choose load or unload an follow the automatic procedure instructions.
For every material, an extruder must be heated before operation. You can preheat the extruders to speedup the proccess.
The load/unload procedure is split into three steps: on the first step a feeder captures filament and you confirm it through the menu. On the second, stepper motor works at high rate, pushing material to extruder. On the third step, filament is gently transferred to hotend on a lower speed, and you need to confirm the material comes out of the nozzle.
For composite fiber there is a 4th step – you need to remove the cut fiber out of the nozzle using tweezers.
In some cases you might want to just move a material in/out of an extruder. In this case use Movement option as described here.
Another trick is a manual unload of plastic filament. When extruder is heated enough to release the filament inside, just release the clamp of the feeder and pull the filament out.
2.Heating and cooling extruders
On the Main Screen, press the extruder you want to heat and set the desired temperature using the arrows as shown below. Press Set button to start the heating proccess.
Usually, the value you choose is the work temperature of the loaded plastic.
The Auto button allows you to choose the last temperature used for this extruder. Press Set to start heating.
The Cool button sets the room temperature for this extruder.
3.Printhead and extruders operation
You can move the printhead of your Composer to any point in the build area. To do this, on the Main Screen press Maintenance > Move. Choose a move distance and press axis arrows to move.
To move a filament back or forward, press Maintenance > Move > Extruders, choose a move distance and use extruder arrows to move. E stands for plastic filament in the plastic extruder, U and V for composite fiber and composite plastic respectively.
You can also cut the fiber by pressing the Scissors icon.
