Step 1: Check Wiring
Before you start with the commissioning of the Sintratec Kit, it is important to double check the wiring of your kit.
Make sure all wires and cables are connected correctly and the wiring is tidy. Make sure the limit switch cables are well separated from other cables (especially from the heating element cables and stepper motor cables). Check, if the electrical contacts of the C14 power entry socket are insulated with electrical tape.
Please check the following wire connections in detail to prevent any damage to your Sintratec Kit:
Step 2: Insert Fuse
Insert the blue DC 15A fuse into its socket on the mainboard if you haven’t done so yet.
Step 3: Mount Lense
Insert the focus lense with the convex side pointing to the galvo system into the lense holder. Mount the lens holder as close as possible to the galvo system to get the best focus.
Step 4: Connect
Connect the USB Cable to your Sintratec Kit and to your computer. Insert the SD card into its socket at the backside of the Sintratec Kit.
Connect the power entry cable to your Sintratec Kit and to your wall power plug.
Always make sure you and other people in the same room are wearing the provided laser safety goggles while working on the Sintratec Kit when the Hat is open.
Step 5: Install Sintratec Central
Step 6: Test the Components
In this step the stepper motors, the heating elements and its temperature sensors of the Sintratec Kit are tested. To control the different components, you have to use Sintratec Central. All functions of the software are described in detail in the Software manual.
First you need to check if the three stepper motors are working properly. Switch to the tab “3. Powder”. Move the two platforms using the arrow icons and move the coater using the “Apply” button.
Coil, IR lamps and IR sensor
Secondly you need to check if the heating elements and the temperature sensors are working properly. Switch to the tab “4. Print”. Click on heat up.
Also check if both, the powder surface temperature and the heating coil temperature are read out by the sensors (check if temperature readings change).
Step 7: Calibrate the Laser
In this step the laser is calibrated and tested. Always make sure you and other people in the same room are wearing the provided laser safety goggles when working with the laser while the Sintratec Kit Hat is open. Abide your countries regulation concerning laser safety.
To shift the calibration pattern to right turn the upper galvo counterclockwise. Turn clockwise to shift to left.
To shift the calibration pattern down turn the lower galvo counterclockwise. Turn clockwise to shift up.
Galvo Driver Y-Axis
To stretch the calibration pattern in the Y-axis turn the screw of the Y-axis galvo driver clockwise. Turn counterclockwise to compress.
Galvo Driver X-Axis
To stretch the calibration pattern in the X-axis turn the screw of the X-axis galvo driver clockwise. Turn counterclockwise to compress.
