DiamondMinds, RPi and GitHub

[Nate Walker]

Just thought this one might be of interest to those who have been working on the printers.

I can drop in a Raspberry Pi and USB webcam to use, if anyone would like to tackle this task on Sunday?

If there is the interest we can hook up 3 of the rPis semi-permanently for this as well.

Good morning DM'ers,

There are two Github repositories for the two current models of DiamondMind 3d Printers, they can be found here:
https://github.com/DiamondMind3DPrinters

I have just updated both with the details on how to attach a Raspberry Pi and utilise OctoPrint to print via .gcode files uploaded via it's web interface. It also has the ability, via an attached USB video camera, to record a time-lapse of the build (I recommend a photo at every z-axis change for less epilepsy inducing timelapses).

The following is a quick outline of the steps I went through to get it up and running:

• Installed the OctoPi distribution onto a shiny new Sandisk 8GB SD Card.
• Plugged it into a spare RPi, along with USB hub, network cable, keyboard, mouse, DiamondMind printer and MS LifeCam 5000.
• 
  
• Powered it on, configured the Raspbian side of things - expand FS, secure "pi" password, start X on boot...
• Booted to desktop and wondered what was going on - nothing to see here except for a standard Raspbian desktop/install - checked what IP address was and made a note of this.
• Jumped on a PC - http://octopi.local didn't work so used the RPi's IP address instead...
• Have printed a couple of things using OctoPrint without a glitch, workflow is a little different:

1. Load .stl into Repetier
2. Place in desired location.
3. Slice with desired settings
4. Save the generated GCode - all my .stl files are on a Google Drive shared folder - one thing to mention here, printing this: http://www.thingiverse.com/thing:106822 - you will need to remove the "home x-axis" {G28 X0  ; home X axis} at the very end with any object that is higher than 70mm - as the carriage is not able to 'home' due to the constraints of the side holes.
5. Browse to OctoPrint IP - upload Gcode
6. "Load and Print"

• Might need to play around with printer settings within OctoPrint but so far the built-in defaults work fine.

Happy Pi Printing,

Jack,
I'm hoping to call in on Sunday for a bit, weather permitting.
If not then I will have to make it the Sunday afterwards.

Unfortunately I can't make it today, I have a matinee performance of
The Producers this afternoon. Next Sunday is a possibility.

Cheers,
Jack
