To extend the service life of the Composer CFC Printer, the mechanical parts of the product must be serviced periodically. The
service includes lubrication of moving nodes: guides of X, Y, Z-axes, Z-axis screw and plastic extruder. The delivery package includes
two types of lubricants: for the plastic nozzle and guide axes. lubrication of mechanical parts of the printer is recommended at least
once every six months.
You may need to go through calibration procedure every time you replace a nozzle or after any other changes affecting relative positioning of the printhead and the buildplate, e.g. shaking or moving the printer. While printing a large part occupying the whole buildplate area, you can notice layer thickness varies from one end of the part to another, which as well means the buildplate requires recalibration.
It’s highly recommended to preheat plastic nozzle before calibration as described here.
To start calibration, on the main screen press Maintenance. Choose Calibrate > Buildplate. Follow instructions. First, you will be asked to set the plastic nozzle in approximately 1 mm from the buildplate. The first of 3 points is to be set through the calibration menu, and the left and right corners are tuned manually by adjusting the regulation screws. Second, the procedure is to be repeated for fine tuning, this time using a sheet of an office paper to set the lowest possible gap between the nozzle and the buildplate. The paper must be sliding in the gap with a slight friction. Setting insufficiently low gap will lead to failed prints and printer malfunction.
It is recommended to calibrate Z axis right after buildplate calibration.
The latest Composer firmware can be downloaded here.
To update printer firmware you can use Anisoprint Aura. Install and launch Aura.
If you connect Composer to your PC for the first time you may need to install the USB driver. To install the driver unzip the archive and run dpinst-amd64.exe if you have 64-bit OS or dpinst-x86.exe if you have 32-bit OS.
Connect the printer to the PC by USB cable. In Aura main menu open Tools >Composerfirmware update.
In Composer firmware update tool:
In Portlist select the COM port of Composer. If you connected Composer to your PC for the first time, it will usually be the last one. If the list is empty or you can’t connect to printer using any listed port, make sure, that you have installed SUB driver mentioned above.
Click on “…” button near Pathfield and select Composer firmware file.
Wait until all lines including the last “Success” button become green.
Do not disconnect or turn off your printer during firmware update process.
Composer A4 uses three spool: 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 spool 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.
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.
