# Cura Post-Process plugin
# Combines 'Display Filename and Layer on the LCD' with 'Display Progress'
# Combined and with additions by: GregValiant (Greg Foresi)
# Date:       September 8, 2023
# NOTE:  This combined post processor will make 'Display Filename and Layer on the LCD' and 'Display Progress' obsolete
# Description:  Display Filename and Layer options:
#       Status messages sent to the printer...
#           - Scrolling (SCROLL_LONG_FILENAMES) if enabled in Marlin and you aren't printing a small item select this option.
#           - Name: By default it will use the name generated by Cura (EG: TT_Test_Cube) - You may enter a custom name here
#           - Start Num: Choose which number you prefer for the initial layer, 0 or 1
#           - Max Layer: Enabling this will show how many layers are in the entire print (EG: Layer 1 of 265!)
#           - Add prefix 'Printing': Enabling this will add the prefix 'Printing'
#           - Example Line on LCD:  Printing Layer 0 of 395 3DBenchy
#       Display Progress options:
#           - Display Total Layer Count
#           - Disply Time Remaining for the print
#           - Time Fudge Factor % - Divide the Actual Print Time by the Cura Estimate.  Enter as a percentage and the displayed time will be adjusted.  This allows you to bring the displayed time closer to reality (Ex: Entering 87.5 would indicate an adjustment to 87.5% of the Cura estimate).
#           - Example line on LCD:  1/479 | ET 2h13m
#           - Time to Pauses changes the M117/M118 lines to countdown to the next pause as  1/479 | TP 2h36m
#           - 'Add M118 Line' is available with either option.  M118 will bounce the message back to a remote print server through the USB connection.
#           - 'Add M73 Line' is used by 'Display Progress' only.  There are options to incluse M73 P(percent) and M73 R(time remaining)
#           - Enable 'Finish-Time' Message - when enabled, takes the Print Time and calculates when the print will end.  It takes into account the Time Fudge Factor.  The user may enter a print start time.  This is also available for Display Filename.
