What is the problem?
Gcode viewer is several layers ahead as compared to DisplayLayerProgress plugin, or PrettyGCode or the actual physical print as observed. Number of layers ahead varies. It seems to get larger as the print proceeds observed difference was 7 layers ahead at the beginning of the print and now 9 layers.
The number of layers in Model Info is correct. I suspect that by the end of the print it may correct by the end of the print.
Now at 88% about 14 hours into the print it is showing 140/249 whereas DisplayLayerProgress shows 170/248 so it is running behind now.
Now it is at 97% and 210/249 whereas DisplaylayerProgress is 207/248.
I'll post a new log at the print end.
Posted, and it is a much smaller file.
