I’m looking forward to seeing the final video when it’s ready, but for now, head on over to Instructables to read the written version. Repeatable computer controlled moves mean you can make exactly the same shot over and over and over again, allowing for all kinds of cool composites and other creative effects in post. The resulting footage in the demo video at the top is pretty awesome. As well as Bluetooth control, it also has controls and an OLED display built in, too. He hasn’t designed a custom app for it, but he uses the Serial Bluetooth Terminal app to connect to his “Edelclone” (yup, that’s what he called it). Advertisementsīecause it uses an ESP32, which features built-in Bluetooth, the slider can also take advantage of Bluetooth control from your smartphone. This is the first part of a series of articles for the Raspberry Pi GPIO pin usage. Stepper speed control: Control the stepping speed with a potentiometer. Stepper one step at a time: Turn the shaft step by step to check the proper wiring of the motor. Stepper one revolution: Turn the shaft one revolution clockwise and one counterclockwise. This article uses the built-in RPi.GPIO Python library to create scripts for blinking a LED and using a button as input. Motor knob: Control a highly accurate stepper motor using a potentiometer. Configuration files have been provided for the Arduino/Ramps combo, but the final section of those configuration files shows the things you’d need to change for other boards – and he lists some specific things on the Instructables page for the SKR Mini E3 V2.0 (although, personally, I’d avoid boards that won’t let you swap out the stepper drivers). A detailed tutorial on using Raspberry Pi GPIO pins. The controller board runs Marlin, which is the default go-to firmware for most 3D printers, although as it’s not being used for a 3D printer, it requires some configuration tweaks. Dslrdiy used an Arduino Mega with a Ramps board as his controller, but if you don’t already have a board you can reuse, check out the SKR boards from BigTreeTech – it’ll probably work out cheaper than the Arduino/Ramps combo and they’re 32-Bit, which should result in smoother motion at higher speeds. It could be anywhere form a few bucks to a couple of hundred depending on how much you need and how fancy you want to get with it. ![]() The total cost will depend on what you might have lying around already that you can reuse. GT2 20 tooth pulleys and GT2 60 tooth pulleys I designed the gimbal using a 3D modeling software.3 or 4 Stepper motors the bigger the stronger.There are a few other things you’ll need to buy anyway and he has posted a list. If you don’t have an old 3D printer lying around that you can cannibalise, you can of course just go and buy the components. ![]() It reuses the stepper motors, controller board, 2020 aluminium extrusion, steel rods and various other things typically found on many FDM 3D printers. Dslrdiy cannibalised parts from old 3D printers in order to bring his slider to life.
