I searched but didn't find anything on this topic. Maybe it's not worth the trouble.
I looked for a plug-in that would keep track of total print hours with user settable alerts for upcoming periodic maintenance.
Items like cleaning and oiling rods or bearings, or just to know how many hour you have total. Sort of like an hourmeter on a piece of equipment. You could also use it to track hours printing each day and maybe save to a .CSV file so you could use Excel or another spreadsheet to plot print time by hour/day/week/month.
Does anything exist like this now? I do not have ability to create a plug-in so please don't suggest that I write one, it won't happen because I stink at coding.
You've got know your limitations and that is one of mine.
