Hello Shahin!
Could you check my settings? After pressing Stop build plate going all the way up. After pressing Resume it starts project new layers without even platform moving.
Look at the images please.

I could find two issues on your after layer gcode box which probably causing unexpected behavior.
After layer gcode box you have:
G1 Z{[[LayerPosition]]+[[ZLiftDistance]]} F{[[ZSpeed]]/5} P1 ; Lift to wait position
[[WaitForDoneMessage]]
[[PositionSet [[LayerPosition]]]]
But you should have
G1 Z{[[LayerPosition]]+[[ZLiftDistance]]} F{[[ZSpeed]]/5} P1 ; Lift to wait position
[[WaitForDoneMessage]]
[[PositionSet {[[LayerPosition]]+[[ZLiftDistance]]}]]
Also you should correct finish/stop gcode or resume gcode
G90 ; Put positioning in absolute mode
G92 Z[[CurrentPosition]] Y0 X0 ; System crashed so we need to recover current position from nanodlp and set it on RAMP
G1 Z[[LayerPosition]] ; Move to layer position
But if you compare resume with finish gcodes, code try recover position from nanodlp without moving RAMPS to correct position.
So I expect something like below line required on resume, also you do not have [[WaitForDoneMessage]] so nanodlp does not wait for movement to get completed.
G1 Z[[CurrentPosition]]

Hello Shahin!
Could you check if I understand you proper way please/
Resume Print Gcode:
G90 ; Put positioning in absolute mode
G92 Z[[CurrentPosition]] Y0 X0 ; System crashed so we need to recover current position from nanodlp and set it on RAMP
G1 Z[[LayerPosition]] ; Move to layer position
[[WaitForDoneMessage]]
G1 Z[[CurrentPosition]]
and
Print Stop Gcode:
M107
G04 F30000
G90 ; Put positioning in absolute mode
G92 Z[[CurrentPosition]] Y0 X0 ; System crashed so we need to recover current position from nanodlp and set it on RAMP
G1 Z185 F300
M84
In resin Profile
GCODE Before Each Layer:
G1 Z[[LayerPosition]] F[[ZSpeed]] P1 ; Move to layer position
[[WaitForDoneMessage]]
[[PositionSet [[LayerPosition]]]]
GCODE After Each Layer:
G1 Z{[[LayerPosition]]+[[ZLiftDistance]]} F{[[ZSpeed]]/5} P1 ; Lift to wait position
[[WaitForDoneMessage]]
[[PositionSet {[[LayerPosition]]+[[ZLiftDistance]]}]]
Is it correct?
Also I have few more questions.
Does Wanhao D7 have:
1. Hardware Fault Detection (current setting - Disable)
2. Stop/Shutdown Physical Buttons
3. Wait GPIO (current setting - Disable)
4. Movement Positioning (current setting - Relative)
Thank you very much!

Just performed dry print. Resume did not work as should be. Platform remained at upper position or a little bit lower while should be go down to 11 layer.

There still some mistakes. You need to wait for each movement. So after each G1 G28 or similar commands (depend on RAMPS firmware) you need [[WaitForDoneMessage]]. Also after each movement you need to update current position on nanodlp side. Also you should consider positioning mode of the axis, if it is in absolute or relative mode.
.
1. Hardware Fault Detection (current setting - Disable)
No
2. Stop/Shutdown Physical Buttons
No
3. Wait GPIO (current setting - Disable)
No
4. Movement Positioning (current setting - Relative)
It depends for manual button relative is required so best practice is to enter absolute mode during printing or handle all gcodes in relative mode.

Did not know D7 users could not use resume function. I am sure Muve3D provides resume correctly. I am not sure about Phrozen but I believe it should be OK too.

One Facebook user sujests to change in current resin profile lift distance while printing. It works, but lift performs too slow (2 mm lift with speed 0.1 mm/sec is ok, but 50 mm with it - no.) What we do not need at all - loosing steps while moving up and down.
Offline
Other Facebook user sujests to use PAUSE button instead STOP.
And then at Z-axis movements use MOVE Z axis UP 50/100 and DOWN 50/100. Then RESUME.
Checked it. It worked fine.
I modified Move UP/Down buttons gcode with Z100 F300/Z-100 F300 to lower speed movement.

So does resume in fact not work on a D7?

DrNK,
Ideally you need to keep correct position on both NanoDLP and Ramps and sync RAMPS through NanoDLP.
It update NanoDLP position (even though internally it calculate updated you may need it for calibration and etc)
[[PositionSet ]]
G92 also set position on RAMPS side.
Only for resume and boot codes you need recovery sequence. Resume if manual movement happen (the most gcodes out there are wrong for nanodlp so manual movement brake positioning), or after system reboot.
It is highly depend on calibration process.
