Switch to a power supply that can supply more amperage and try again. Note that if you run into issues later, such as WiFi not working, it's probably because your power supply cannot supply enough power. The disk will be unreadable when done and your Mac (or maybe Windows machine too) will prompt you to eject it.Įject it from your computer and insert the SD card into your Orange Pi. for the target device, pick the SD card you inserted.for the image, pick the Armbian_5.65_Orangepipcplus_Ubuntu_bionic_next_4.14.78.img file you downloaded.insert a MicroSD card into your computer.The full armbian guide to install to eMMC is here, but I'll walk you through the steps in this guide as well.ĭownload the latest version for your board and extract the 7z file, on my mac this is done in the terminal with:Ĭreate a bootable MicroSD card as follows: This way, we can use the MicroSD slot for something else. First order of business is installing the OS onto the 8GB onboard eMMC, which is sort of like an SD card soldered right to the board. Installing the Operating systemĪs mentioned, I'm using armbian on my Orange Pi PC. If your board is unreliable or reboots randomly or is doing other strange things, it is likely your power supply is the problem. I will be using a 3A, 5v Voltage Regulator to power the Orange Pi PC.īe sure to pick a power source that can provide the maximum current your board requires +20% extra. I resorted to using a wireless mouse / keyboard combo Power considerations Note that the display is easy to get working, just plug it in, but the touch screen is much more difficult and your luck may vary depending on the precise display. You'll also need a short HDMI cable if you're using an HDMI display. Optionally, we'll install a 5" HDMI display with a resistive touch panel. You can see the list of boards supported by armbian here and any one of these with specs similar or greater than the Raspberry Pi 3 should work fine. Armbian is an Ubuntu port for many ARM based SBCs. I will be using armbian for the operating system. There are many, many SBCs with similar specs. I also tested out an Orange Pi Zero 512Mb I have on hand which runs fine without the display. Running the whole printer stack plus Firefox, load on the Orange Pi PC Plus seems reasonable while printing: That said, I will be using the Orange Pi PC Plus I have on hand. Klipper needs a reasonable amount of computational power and while it can be run on any single board computer, a Raspberry Pi 3 is recommended This could be solved by a soft power switch, but I haven't gotten around to this yet. The one downside of this setup is that the SBC needs to be properly powered down before turning off the power supply. This allows for faster, more accurate motion planning and, hopefully, better prints. No need to use an SDCard to copy gcode files from the computer to the printer anymore, simply upload to OctoPrint and print away! The web UI is standard Octoprint, or you can install the Octoprint TouchUI plugin as shown above, depending what you prefer.Įven better though, Klipper offloads the motion planning from the control board to the single board computer. Klipper is convenient in that the printer can be controlled via a WiFi interface. I've also added a touchscreen display to the SBC running Klipper for easy printer control. I have been exploring different firmware options for my TronXY X5S 3D Printer, and Klipper is interesting in that it runs the CNC control on a single board computer (SBC) and uses the 3D printer's control board as a motor controller.
