Before I get to the point, here's a tip:  Large files can hang up on uploading - to help fix this, do the following:
Go to Tool>Firmware Config>Communication
  Increase the cache size (had to set mine to 2047 (1 less than 2048) and set the Timeout to 60 sec.
 

XYZware has three major print settings:  Normal, Good and Excellent
In Simplify3D, select the Da Vinci 1 process and modify the defaults to match XYZware, as follows:

For Normal
  Density = 5%  (means the same as infill)
  Height = 0.4
  Layers = 2  (this applies to both Top and Bottom)
  Shell = 1
  Bed Temp = 90
  Extruder Temp = 215
  Speed = as is

For Good
  Density = 5%
  Height = 0.3
  Layers = 2
  Shell = 2
  Bed Temp = 90
  Extruder Temp = 215
  Speed = as is

For Excellent
  Density = 10%
  Height = 0.2
  Layers = 3
  Shell = 3
  Bed Temp = 90
  Extruder Temp = 215
  Speed = as is

Improvements to the above settings:
Simplify3D enables setting several parameters that improve the print but, the values depend on the model you’re printing - one size doesn’t fit all, so to speak.
Density can always improve the structural integrity (hold off increasing until you're happy with everything else about the print).
Layers and shells - depends on the model (things like thickness and corner radius and logo’s, text…).
Outline overlap, solid layer at every #layers (really helps structural integrity).

Consider some test parts such as creating something like a coin with image and text, thin and thick wall parts, have some overhangs at 45 deg, 55 deg  - some parts won't droop, some will - it's mostly about experiment and features on your model.

Currently Black ABS (XYZprint brand) is difficult to buy so I'm using Shaxon with a Zerocart (to trick the printer).  Had to increase the Extruder Temp to 220 for better print with Shaxon.

I've found that one shell is way too thin however. XYZware's settings are pretty ambiguous, I think their "medium" setting is pretty close to three shells.

As someone who has a DaVinci 1.0 connected to my computer through USB and who has been using Simplify3d for quite a while now, I can assure you that once the print job is sent to the printer, you are good to disconnect.

Believe it or not, your choice

I believe you, honest.   

I just purchased it and I am figuring some things out with it.  So far I am impressed by the program.  It does appear to upload to the printer like XYZware.  Since I am on stock with stock firmware I was not sure what you had, so some doubt crept in.  I think the feedback I was receiving was just the current stats like temp, etc.

I do have a follow-up question about shell thickness in Simplifiy3D.  I am at work so I don't have it right in front of me, but what would be the corresponding numbers in Simplify3D to the shell thickness settings in XYZware?  I think, if I can recall, the default number for me was 2 in Simplify3D.

Thanks

I have SD3 and yes you can unplug once the print job is sent you can disconnect from the printer.

Same here.

Thanks for the replies.  It seems there is a difference of opinion.  My machine is stock (no repetier).  It seems to upload to the machine ok.  When I print over USB I see Simplify3D giving real time feedback. 

So am I safe in turning my computer off once the printer starts?

You know you could just start a garbage print and unplug it. That would remove all speculation and mixed opinions.

If it is showing real time data then that means SD3 is talking to the printer in real time over USB so you would not be able to unplug it.

True enough.  Perhaps I will.

Most of the time, my computer is asleep while the print is ongoing.
