Description

I have had my Da Vinci now for a week and need to figure out what is driving this machine. Taking off the electronics panel the electronics looks very similar to other 3D printer. This machine did have an on board 4gb SD card. After cutting the case it was easy to remove the SD card. Loaded the card into my computer, I found some interesting files, but no propriety .3W files. The SD card did have standard Gcode files loaded onto it. So I open Slic3r 10.0 and slic3r the twisted bottle. After hand modifying the files first lines I renamed it SAMPLE03.gcode, then loaded it onto the SD card. Loaded the SD card back into the machine and printed the demo Vase (AKA SAMPLE03.gcode). Twisted Bottle started printing as as expected. It is very possible to use Slic3r or other opensource software on this machine .Interesting thing I also found on the SD card was a file called offline_print.gcode. I think the XZYware software spits out a .3w files to you desktop, but exports a Gcode files to the machine. From what I can tell the machine does not decompile the .3W file to a gcode file. If somebody could connect to the machine and export gcode files to the machine it probably would run just fine. It also would be possible to Change the extrude temperature in Slic3r and start printing with PLA or Nylon but leave the material = abs in the file.
