5.6 REPLENISHING MATERIAL
In the event of changing lament color during printing, or if the amount of material on the spool is too small to build the entire model,
it is possible to swap the material during the process.
STEP 1
During printing choose the right moment and click CHANGE. The printer stops once commands cached in the memory are completed.
STEP 2
Once the print head has stopped go to menu OPERATOR PANEL as soon as possible, and select DOWN several times until the Build
Table travels down by ca. 50 mm.
STEP 3
Using the four FRONT, BACK, LEFT, RIGHT buttons position the carriage in a place convenient to change materials.
STEP 4
Follow the changing material procedure. Decouple the extruder push-t connector and remove the Teon lament guide tube, then
press extruder lever and remove material from the print head. (Refer to chapter “Changing material” on page 23).
Extruder may be hot! Be sure to wear protective gloves!
STEP 5
While holding the pressure lever and with decoupled lament guide tube, grasp lament a few centimeters above the extruder and
push it in through the print head until a continuous thread exits the nozzle.
STEP 6
Remove the pressed lament thread and couple lament guide tube to extruder push-t connector.
STEP 7
On the display, select BACK , then UNPAUSE. The printer will resume printing from where it has stopped.
5.7 STARTING A PRINT
We assume that:
1. relevant .gcode le has been saved on the SD card;
2. printing platform is clean and Dimax spray has been applied;
3. correct material has been loaded;
4. the device has correct nozzle installed in it.
To start a print, select the relevant print le from the list in menu PRINT, then conrm your selection by pressing OK. Now, the carriage
is reset to the home position and the build table starts resetting to zero.
Every time you touch the extruder or carriage when homeing the build table may result in its early stoppage
and error in starting print!
Before selecting the print le make sure that no lament residue remains on the nozzle. It the nozzle is
crusted you must clean it.
Once resetting the printer is nished, the device is warmed up to an appropriate printing temperature and thermally stabilized. It can
take several minutes. Then, the printing process starts automatically.
