Just finished running a print on my davinci pro. All I had to do was go to the Help menu, select Configuration Assistant, then I just picked the XYZprinting 1.0 Pro profile. It rearranged the build plate and loaded all the settings. I plugged in my printer and it automatically connected. I went to the machine control panel and it was already reporting the bed and extruder temperatures, so everything looks good.
To actually start the print, I just imported a simple calibration model, sliced it, and then clicked Print over USB. Sure enough, I heard the davinci pro beep a few times and the file started uploading and printing. After several months of being forced to use the bad XYZ software, I can't say how exciting this is. It's behaving just like the other reprap printers I have and it seems I can do most anything that I can do with them in S3D.
The print only took about 15 minutes, but it looks even better than what I was getting. Plus now I get to use all the other goodies in the simplify slicer
While it was printing, I also saw that the percent complete was being sent back to the S3D window and the preview was actually following along with the print. I don't remember this ever working on my old da vinci 1.0. Has anyone else noticed this? I'm thinking this may also be something new they added in v3.1...
EDIT: The davinci pro firmware doesn't support manually jogging, so don't expect that to work. The software gives you a warning to confirm this.
