My first question in this forum But I'm sure I'll have more.
I'm using Cura 15.04.6 to prepare my files to print with 1.75mm Hatchbox PLA on my ONI Kage Tall. I'm trying to keep detailed records about estimated print times as well as estimated weight of each print. And when each print is done I also record the actual print time so I can compare it with the estimated time.
I know this is pretty standard operating procedure but I'll say it anyway. The reason for recording the est. time and real time is so I know when to go remove a print and start a new one if I need to. the reason for recording the estimate weight is I can figure out if there will be enough on any given reel of filament for the next print, or to see if maybe it's time to put on a different reel sp I don't run out of filament mid print and waste time and material.
So what my question is, are the estimated time and estimated print weight directly related to each other in a reliable and constant manner. Here is what I've encountered. CURA 15.04.6 has consistently over estimated my print time and not by just a minute or two on my longer prints. Here is an example of a recent print: Estimated Time - 35 Hours 28 Minnutes --- Real Time - 30 Hours 37 Minutes. So in this instance my actual print time is 86.32% of the time estimated by CURA. Could this time ratio be applied to more accurately figure out how much filament was actually used? The estimated weight of this print was 517 Grams. Would it be reasonably accurate to calculate this to be 517 x .8632 = 446.3 Grams?
I know the simple way to figure out how much has been used off a reel is to physically weight each print, but I don't have a gram scale and was hoping this maybe a reasonable alternative?
