Using a Raspberry Pi + Octopi to manage your printer

[PyramidDave]

I saw someone was looking for a way to clear their prints off the build plate remotely. There was a new design on thingiverse that seems to handle that problem. Take a look at this novel design if you have not seen it. http://www.thingiverse.com/thing:872617
It probably would not work well for buildtak or similar surfaces. I have to pry parts off with a knife from the buildtak surface sometimes.

Trying to get Octoprint to work and when I try and print something I get a waiting for user message on the LCD display. Nothing prints.

It's a known issue for this to happen with Pronterface connected and monitoring temperatures. I have never seen it with Octoprint. With Pronterface, clicking the dial on the printer LCD acknowledges the message and allows the printer to continue.

I have seen this with Octoprint and auto bed leveling enabled. The host side will timeout during bed probing. The pathology I saw was during the bed probing, octopi will timeout and the printer will display a message "M105" and stall until the user presses the the dial on the printer LCD as clough42 describes.

Once I changed all of the timeout settings (except auto detect) to 30 seconds this stopped happening.

You may need much more than 30 seconds for homing if the carriage is way up high. I think I'm running something more like 150 or 200.

Has anyone implemented these neat add ons sucessfully?

I have been trying to get these working to finish off my install but whenever I modify the config.yam1 file the server becomes inaccesible and I get a 503 error on my webbrower if I access it locally or over the internet. I feel like I dont get the syntax correct for adding these changes but if anyone else has managed todo this and could shed some light it would be much appreciated.

With a google search, I found these 3 web pages that may help you with yaml syntax.

That was very very helpful turns out I was spacing things incorrectly. Thanks alot.

Unfortunately I've hit a new roadblock. Previously I didnt have an issue connecting to the printer and I hve tested moving the printer axes before. Now after uploading my first file it throws an error when i try to connect to the printer saying Machine Status: Error:volume.init failed. Any ideas what might be causing this?

Hmm I take that back turns out just because the server error is gone doesnt mean I entered the information in correctly...I commented out the section I added and tried again and was able to connect. Damn it.

At least it is working for you now. Hope you figure it out. I have not tried the task you are attempting. Maybe someone else here will have a suggestion for you.
