It may contend for serial resources.Īs far as nubi's I can understand a "standard" config that's pretty bulletproof. I'm not using the Ethernet port that's on the external hub. The USB also has a limited FIFO buffer in case the cpu is busy. All the pi sees is that parallel data is available. For Outsourced, The UART takes serial and converts it to parallel in hardware. I'm using an external hub since I need 2 usb ports. Just be aware of netork traffic and CPU intensive stuff.Īgree big time with cpu maxed out at 100% when rendering. So the Zero W is absolute a possibility, especially for the price. That is another reason to keep it running. It takes around 5 minutes for the Zero W to start up and settle with CPU usage under 50%. I keep Octoprint / Octopi running 24/7 though. I do have a Tasmota Sonoff S20 to control the printer, so I can turn it off if I see something going wrong. I have been using it with telegram to observe long prints from work. To have easy buttons to move printhead/bed around. I do not capture printing video anyway I have Octoprint to allow me to easily upload files from Cura to the printer (Octoprint) avoiding the memory card swap, to see the progress and time estimates, to cancel a print. So no camera on the Pi, get a standalone IP camera.
Its biggest problem is supposedly CPU usage with wireless data transfer while printing. So nothing wrong with the Zero W, as long as you use it within its parameters. Installing is way slower than my old Linux do-it-all box in the corner, but needed to move the printer. Installed Octopi, and it is just running. Just bought a Pi Zero W, as it is dirt cheap.
