Justine and Lars are studying Media, Management and Journalism at the Jade Hochschule. Now they took pictures of the latest papercube version. Here is one of the results: Our photo of the day.
This is papercube V3. The big construction in the middle is the laser enclosure. On the left side is the paper feed. On the right side is the lift for the paper, followed by the folding mechanism.

We finally did our first test run of the complete laser unit within the assembled laser enclosure.
LEGO Mindstorms Education-based process for manufacturing paper cubes
We have finalised the pen unit for the students. To introduce it to them, we made a video. The students will be able to preview there programed instructions in the simulator and afterwards print them using the pen unit. Our laser unit is controlled by the same simulator, furthermore it shows live feedback on the printing progress.
We finally automated the laser cutting by using a digital to analog converter (DAC), connected via #I2C to one of the sensor ports of an #LEGOMindstormsEV3. We created a custom board featuring a #Adafruit #MCP4725 DAC.
After some tests to verify everything was working correctly we hooked it up to the laser to do the very first automated laser run. We are very proud that everything is controlled by only one EV3 Brick programmed in Java using the LeJOS firmware.

Today the paper cube team has worked again.
The aim was to test the laser for cutting and slitting the paper. With the help of a small Java program, the motors of the cutting unit has been activated and a test is performed. We are very pleased with the initial results. What do you think?
Jens and Fabrice are members of the papercube project team. In the last days they have been working on our „Module 1“ (The CuttingModule . The carriage with the pencil is used for training purposes in the Java lecture . Later, it is replaced by a laser module . Then it’s possible to cut the paper . The film can be seen exactly how the unit works . We are always impressed how accurate can be constructed with LEGO.
