Notice that XYZware moved .35 mm on the Z axis. XYZ apparently decided that initial layer should be .35 since you can't change that setting.

I assume that means I should set the Z-Offset in Kisslicer to -0.35mm? Will try this out, might work.

EDIT: Setting the offset to a negative value moves the bed down right? I hope it is not the other way round, don't want to damage anything...

Just reread that.  Ill look into 3rd party slicer programs, I've only used XYZware.  Measuring the test strip it lays down before the main print, its .26-.28mm thick.  I suppose I could also try the paper trick bed leveling technique to get the proper distance.

On the DaVinci the Z-offset is stored by the firmware, it's a specific amount the bed moves down from the Z stop sensor and is accounted for in XYZware (this isn't the same as manually jogging the Z axis).

Other slicers may or may not deal with this issue well. For instance, the start of a print job if sliced by Cura looks like this (only the line that matters shown) G0 F2700 X71.80 Y71.80 Z0.30. Now all of the G0 commands must be changed to G1 to print on DaVinci, but the important part is that last Z0.30 which means the bed will be moved down .3 mm from where the printer thinks that Z home is. Cura then prints a skirt around the object and starts printing. I have the initial layer in Cura set at .3 which is why that number appears.

In XYZware that same command looks like G1 Z0.350 F2700.000 and it will issue a few more movement and a negative extrusion command before it to moves to a spot on the edge of the glass for its priming line and then starts its print. Notice that XYZware moved .35 mm on the Z axis. XYZ apparently decided that initial layer should be .35 since you can't change that setting.

Is it possible to adjust the Z-offset with the stock XYZware and current firmware, or do I need to use a different slicer?  I feel as though I have been through every menu but cannot find a Z-offset option.  I think this would solve a lot of my problems and make for cleaner prints.

I use the Z-offset for cleaning and getting at the print bed..is it supposed to be used for fine tuning?  It seems to go back to its original spot once it reboots or begins a print.

Your other option is to adjust with the bed level screws, but then you'll have a fight going back and forth between that and XYZware.
