You can find a micro USB to USB2.0 TYPE B cable, they do exist in china. The Pizero only has MicroUSB ports, so you need connect this one with an OTG adapter to the “blue” data cable (USB2.0 TYPE B, the square port). This one will send Octoprint's instructions (GCODE) to the printer, in the same way your laptop would do.
The second cable, located in the center, is the data port. You can also power it with a USB powerbank for your tests (no fan noise :) ) The one at the side of the case (right on the picture) is the “power” one, you simply connect it with a micro usb cable to the USB thumbdrive port on the A5/A3S : it'll power the pi. Then put it in the PIZERO, boot it and verify it gets an ip adress (eg : in your router)īeware the PIZERO has two USB ports and you need them both I also plan to use the GPIO pins with the Enclosure plugin, and breaking those out with the Zero W inside the einsy case would be more of a pita.Now - as covered in multiple other tutorials (eg ), simply find an image of Octoprint for Pi ( ) flash it on a MicroSD card ( 16 GB or more recommended )Īs the PIZERO doesn't know your network settings yet, mount the flash drive in a PC and edit the network config (įound in /boot/octopi-network.txt ) for your internal LAN's SSID and password. The upside is that it's way faster, and I plan to add a second, USB camera, to have a second POV on the print.
The downside is two more cords to manage. That took over 30 minutes of just compile time (and I had to do more work to get it to work at all, since using stock commands led to various timeouts). I wanted to add a mesh-leveling plugin that needed to be compiled. Bootup took close to 5 min from power-on to web interface responding. Why? Mostly because it was very slow on non-printing tasks. From all I've heard the Zero W can't handle a USB webcam. Note this is with a Pi Camera Module, which uses its own interface to the Pi, not a USB webcam. Worked ok, even when printing, streaming video, and doing timelapse, all at once. I successfully ran OctoPi on a Zero W, using Prusa's image, with a Pi Camera Module.
