Stops timelapses to early

[mjrider]

Hello,

after a few days of tracing code in octoprint..... While running bufferbuddy octoprint finishes the print to early.

Depending on the buffersize config this will be more or less obvious, but mine are large enough that i have around 100 moves 'left' when the final m400 is send by octoprint.

because octoprint doesn't wait for all the buffers to drain on this point the printer is happily printing the finals lines while octoprint thinks the printer is finished.

tested this theory by adding 100 times M400 add the end of the file to make sure the buffer is completely filled with NO-OP's and then the timelapse is just fine.

i don't expect that this plugin can fix this, but it might be usefull to document it as knows issue with workaround
