I recently had the opportunity to purchase a 3D Systems Cube 3 for $47. The reason for this ridiculously low price is the Cube 3 is locked into using proprietary filament and 3D Systems has dropped support for the Cube 3 (there are ways to force the printer to accept open-source filament – on my to do list). The printer was also a demonstration model in the store. When I purchased it, a whole bunch of filament was thrown in for free.

Unfortunately it came without a power supply. Turns out sorting out a replacement was a bit of a mission. It’s a fairly large power supply (24V, 5A) with a somewhat uncommon connector (Kycon KPPX). The connector has 4 pins, of which +24V and GND are distributed across pin pairs. However I could only find affordable power supplies whose pin pair configuration were different to the Cube 3 requirements. As a result, I had to open the power supply up and switch some wires around.

After checking the connections, I plugged the power supply into the Cube 3 and fired it up. After calibrations, cleaning, unjamming, and a few test prints later, the Cube 3 was able to produce something of decent quality.

I still have lots to learn, but no doubt the Cube 3 will be a value piece of equipment.
