Cannot connect to Octopi ( RPI 0 W) after adding pi camera

Hi everybody,

During the last week or so I have tried different solution (this forum and others) on getting a PI camera working on Octopi (prusa) installed on a RPI zero W. I can connect without any problems to Octopi when I just remove the camera but when I'm trying to put it back, no connection (actually I'm browsing to octopi.local and I can't get anything on my browser for minutes - slight bar progress).

Thank you very much

Did you enable the camera already, if not read below.

Hi @shaun.m3,

Thank you very much for your input.

In the meantime I have made some tests and it seems that there might be something wrong with the connection between RPI 0 W and einsy board. I have managed to set the camera and having live preview while I was using RPI 0 W not connected to the einsy board (standalone) just power plugged. This way I have checked that bot RPI 0 W board and camera are working properly.
Now, with RPI connected to ensy, camera connected to RPI but without enabling it in config, I can access Octopi. As soon as I enable camera, the connection to octopi, via browser, stop responding!

octopi.local -> "The OctoPrint server is currently not running"

tried

octopi.local/webcam/ -> picture taken, snapshot working.

Might be worth having a read here below, I know that if my raspberry pi 3+ is not using a really good 5v 3amps power supply, all sorts of weird things happen with slicer.

I stated with a Pi Zero W, assuming that Prusa had made a good design decision. The more I learned, the less convinced I became that was a good choice. Switched to a Pi 3+ and much happier now. Connections are more reliable and a USB camera works well without interfering with OctoPrint.

I rank the Pi Zero W and filament sensor among the least successful design aspects off the Mk3.

I would second that............ 😉

Thank you for your input.

I'm still searching and waiting for some solutions for RPI 0 W. Design wise, this is great.

you are probably exceeding the power available from the EINSY to the PI0 when you add the camera - you might try an external power supply for the PI

The download page for OctoPi( https://octoprint.org/download/ ) indicates that the Raspberry Pi Zero W is to be avoided if trying to utilize with a webcam & Wifi connection - webcam datastream over Wifi causes a huge CPU load, which would explain the lack of response.

I'm surprised the RPi Foundation hasn't released a multi-core unit in the Zero form factor yet. I guess that'd be a bridge too far for the $10 price point, which the Zero is targeted at.
