Octoprint on Raspberry Pi works for Makerbot Replicator2 now.

Could not get Makerware to work on the latest Debian installation.  I installed windows and the Makerware software onto a tiny computer I had. I used NoMachine on this computer and a couple of other computers and pad computers to run the Makerware software.

The next weekend I saw that someone had made a plugin to translate between g-code and whatever it is that my Replicator uses.

Installed Octoprint on a micro SD card and put it in a Raspberry Pi 2 B+.
Plugged the card, USB cable, power, and network cable into the PI.
Once the lights stopped flashing, I found out the IP address using my router.
Typed the IP address into a router.
It took longer to come up the first time because on first boot it expanded the hard drive partition to fill up the SD card.

I had to add the GPX plug in and set it up for my model printer.

Then I had to install Cura on my Debian box, configure Cura for my printer, set up a profile for printing with 2 brims.  I tried printing with a raft, but couldn't get the raft off my prints no matter how I set it up.  Saved this profile, went into the setup for the Cura slicer on the Octopi, and uploaded this profile into the Cura module.

Only once this profile is uploaded can you begin to slice and print. When you upload an STL file you get an option to select this profile (or other profiles you also upload) and then you can do nothing, select it, or select it and print it.

Second step was adding a camera.  Found out that the raspberry pi cameras have to have the lenses unscrewed to focus that close, which involves breaking loose some glue holding the lens in place.  I broke one camera, so be careful.  Important note, unplug the tiny little connector before you try this, and then carefully plug it back in afterwards.  Thinking of making a jig so that this process is fool proof.   This is some good info on the whole process of modding raspberry pi cameras.  Found a spanner to make this easy, if you own a 3D printer, or know someone with one. Print two of them.

Just plugging in the camera and booting the raspberry pi I got a good picture under the control tab.  I clipped a lens adapter onto the lens and got a better picture, had to unscrew the lens to get a good focus.
