A bit behind but still making progress on the Solidoodle SD3 conversion. The bed is on and leveled the old fashioned way…with a level. The top panel is on (new clips for that) and the extruder placement has been tested. Tomorrow, hopefully, I can install the extruder motor and if the polycarbonate door arrives I can install that. If not then the conputer I built out of a stick PC and a converted mini-note LCD, with my wireless keyboard and trackball. Since Ray’s board has no provision for an LCD, I will not bother with it. Originally I was planning to embed that in the door. If Ray’s board is working fine I am unlikely to take it out of service until and if, it actually dies. Nonetheless, this printer will not require a separate PC. @raykholo , your thoughts on using OctoPrint or Astrobox would be appreciated as that will allow me to embed the entire arrangement in the LCD case.
Well, we have the 2 box headers that natively support a GLCD (the sub $10 chinese one works great with these). I have heard that smoothie plays nice with Octoprint, and since Astroprint is based on Octo… but I have not tested either of these myself. The board does have its own wifi built in, we could potentially bridge that to a virtual serial port on any of your computers for streaming a job, but that’s experimental and better options are coming for that. Anyways, try octo, the baud rate is 115200.
And smoothie does also run its own webserver to which you can upload a job and hit print. I forgot to mirror the footprint on this board, but you can make ethernet work with a relatively simple cross over cable and a $6 WaveShare ethernet module from China.
Red printer will only print red 
Nice build 
Nice
Ok so that’s pretty cool. I can park the stick PC arrangement on top of this thing and not run a USB down to the board and go all WiFi. Or, I can run Octo (I do have a Pi available, or two, or three). BUT, this is also all about testing the board. So point me at a GLCD and I will order it or see if I have one lying around. I can run a custom cable (ugly but doable) to that (I will beed pinout details). What do you prefer I test with: Windows 10 and Repetier/Slic3r? Octo? Both? I must say, I am totally enjoying this.

Ethernet: http://s.aliexpress.com/myuaiErU
And some of these for Ethernet crossover: http://s.aliexpress.com/ziEz2EFz
LCD plugs in directly, Ethernet will need a basic crossover, will discuss later. Would be nice to know how Repetier handles Smoothie, I have heard mixed things and I have had freezes on jobs with it. Octo might be a solid backup.
Slic3r and SD card are safest bet.
So be it. I have one of those LCDs sitting right here. It is even inside a case. I will go set it aside an mount it on the case tomorrow. I will do the Ethernet thing later and set a RasPi 2 B+ aside for Octo and start the fun with the stick PC to test Repetier.
