The print progress figures on my Octopi setup are lagging behind the actual print. It is on the latest 1.4.0 rc5 version running on a Pi 3B+ (OctoPi 0.15.1) but I don't think it's a bug as other people would have noticed it. Nothing is broken - anything I throw at it (an Ender 3) prints fine but as a print progresses, the percentage complete, current layer, and sync'd gcode viewer gradually lag behind what is actually being printed. For example, on a print with 400 layers, as the last layer is printed the reported progress and current layer is around 96% and 385 respectively. If I do a quick calculation of the displayed Printed/Total file size figures it works out at 96% but what it has actually printed is over 99%. When the print finishes the numbers jump to 100% and 400 and everything is fine.
I have a few plugins but running in Safe Mode still shows the same issue.
I haven't done any logging yet as it isn't a show stopper and as I said above I don't think it's a bug. I am just curious if anyone else has experienced anything similar or has any suggestions to fix it.
I have a Windows 10 machine and use Chrome Version 79.0.3945.130 - but I am pretty sure it isn't a browser issue. My Ender 3 has been modified with an MKS Gen L V1.0 Controller and runs stock Marlin V1.1.9
Any thoughts welcome.
Quick edit. Based on previous comments by foosel I have checked the gcode files and there isn't any huge additional stuff at the end. I use Cura to slice and there is just a few lines of config data at the end of each file.
