Z-Movment Print Stop / Platform Stop Position / Nextion Move Platform

I have been having trouble with the platform movement for a while.  I thought it was me and my machine but its now happening to both my machines. Both are D7's running the same firmware and nanoDLP versions.

Print Stop Code used to work great. Now it seems to do nothing. The code has not changed and I have tested the gode manually and it seems to work. I have tried entering it line by line and as well as a batch of commands from the terminal console. It executes fine either way.

Then I tried to implement the 'Platform Stop Position'. Looking through my old .json configs, it was not in first few backups that I made.

Here is how the platform stops. Most of my prints are small and I can not tell if its actually above the vat resin level or not. This was a 12.7mm print, 254 layers at 50 microns.

Here is the code snippets-

Here is the end of print from the log file-

The only way to get to the [[GPIOLow 36]] is to have run the entire Print Stop Code, and pressumable parse the movment and wait commands preceeding the last line. But the platform does not move. 

The machine is defined at a height of 195mm. I dont understand why its not moving the platfrom.

Here is a random non-movement from the Nexction. I was able to give it 1 move at 100, then 1 move at 10 and it ended up at 158.95mm.  I am not sure how the math works out from 12.7+100+10 = 122.7 to get to 158.95mm. But trying to move it 1mm, it will not move after button press. 

I know the moon is getting full, and goofy stuff happens in the lunar cycle, but come on, this is nuts.

Anyone have any ideas?

Gcode you are using does not update position on nanodlp side, try use some basic settings working then customize.

Shahin, how do you mean?

The gcode in the 'Print Stop Code' i have executed line by line manually.

what might you suggest to add/insert to communicate with nanoDLP better

M107
G04 S1
M117 Clear Vat Level 
G91
G1 Z50 F400
G90
M117 Raise build platform to top
G1 Z175.00 F400
[[WaitForDoneMessage]]
M84
[[GPIOLow 36]]

[[WaitForDoneMessage]] should be after each command responding similar message from RAMPS side. Currently you have only after last G1 line
