leoleovich / 3djuggler

A daemon to connect 3d Printer to a website

Integration with internal website (intern)

You will need to implement internal website API, which supports following:

/job. Depending on a POST params it should:

• Give a new job
• Give details about job
• Update job status

/printer. Depending on a POST params it should:

• Refresh printer healthcheck
• Reschedule jobs

Every API call must send Username (app) and Password (token) as POST params

Intergration with printer management device:

Printer management device will need to interact with 3djuggler in order to control the job state. By default http server will listern on localhost:8888. Juggler supports following blocking API calls:

/info

Gives information about current job state, printed percentage etc

/start

Start the job

/pause

Pause the job

/cancel

Cancel the job

/reshedule

Give more time before jobs gets marked as "timed out"

/version

In order to use this functionality, you needs to compile juggler with extra flag (see compile section)

Compile

Simply run:

go get github.com/leoleovich/3djuggler
go build github.com/leoleovich/3djuggler

If you want to enable optional /version api - you need to build juggler with extra flag:

go build -ldflags "-X main.gitCommit=123" github.com/leoleovich/3djuggler

Where 123 is a commit hash. You don't have to use this functionality. In this case /version will simply return empty string

How to run

In order to run juggler you will need a config file. Example of this file you can find in this repository. Juggler also supports following There are extra flags you may find useful:

  -config string
    Main config (default "3djuggler.json")
  -log string
    Where to log (default "/var/log/3djuggler.log")
  -verbose
    Use verbose log output

3djuggler's Issues

spontaneous hang-ups due to partial reads from serial port

The "ok" string is read as separate "o" and "k" and therefore not recognised.

[question][documentation] Comparison with OctoPrint

Hello.

Just a humble ask. Is it possible to add info about the reasoning behind this project when OctoPrint already exists. This is really nice to see a simple Go daemon to manage 3D printers remotely, but yet :)

For example right now I use OctoPrint at home, but may be it is better to use this instead. What are the advantages of using using 3djuggler instead of OctoPrint? And what are the supposed use cases?

premature Finished due to "interrupted system call"
