A filmmaker has built a home-made motorized camera rig out of the recycled parts from an aging 3D printer.
The remote four-axis camera slider, which the device’s creator calls “EdelKlone” — an apt joke that makes reference to the company Edelkrone — utilizes not only the stepper motors but also the Arduino and ramps board that controls the movement with Pan and Tilt, as well as movement along a slider.
The design was noticed by Hackaday, which noted that the rig isn’t made from 3D printed parts, so much as parts from a 3D printer.
“I was watching a video about Edelkrone and Rhino’s motorized camera rigs, and I noticed their prices,” says a filmmaker who goes by the handle DSLR DIY.
“Then I remembered I had an extra 3D printer, which has really good resolution. So, I decided to turn it into a 3-4 axis camera head slider.”
DSLR DIY relied on the existing firmware from the 3D printer to create a set of instructions known as G-Code and used those instructions to move along the X, Y, and Z axis in a manner that the motorized camera mount could translate into movement.
In this case, he translated the X axis to Pan, Y to tilt, and Z to slide along his camera slider. It was possible to set a program and adjust the speed.
The G-Code instructions were sent using a UART protocol to the ESP32 controller board built into the 3D printer.
Housed inside of the firmware is the ability to not only preprogram a set of movement instructions but also to manually operate the movement through the manual options built into the original menu.
With a couple of buttons, the creator could move the camera along a predetermined path. This path can be saved as a file so that it can repeat the exact same steps for multiple shots.
DSLR DIY also used a Serial Bluetooth Terminal app on his mobile phone, which can connect to the rig via Bluetooth and send the G-Code commands wirelessly. He was also able to make a remote motion controller.
The design clearly works and DSLR DIY was able to save the $2,750 to $4,000 that photo or video companies would charge for performing the same kind of motorized functions, albeit in a far more elegant fashion.
DSLR DIY has laid out his full build on Instructables for anyone who wants to replicate it.
