Real printing time approximation

thingiverse

I use Simplify3D for a while now and am very satisfied with it ! But a problem (of my printer) with it is that the calculated estimated time from Simplify and the real time the print takes scatters significantly (my printer Prusa i3 clone usually takes much longer than the estimated time) ! So i decided to record the actual print times and write a short Microsoft excel program which compares the estimated & the real printing times and makes a linear regression function which should calculate the real time a print will need when I put in the estimated time from the slicer. Also i added the function that excel takes the actual start time and then calculates the "estimated" end time. Currently I am collecting further data from my prints (the more data the more accurate the program should work). I know i won't eliminate the time difference to zero because retractions, accelerations etc. are different in every model but i hope i will reach a window of + 15-20 minutes or so. The measured data is just usable for my specific printer so you have to record your own data from your slicer / printer. If someone has further improvement thoughts I am happy to hear about it :). Yes i know, a linear regression at this stage is quite brave ^^. (because of publishing reasons i added a .stl file called "eisstaberl" which you can forget ^^) 27.6.2017: in version v3 the slope & axis intercept get calculated automatically. After now 8 measuring points it looks not that bad :)
