Printing time

Hello, I have a big printing problem with my creatr HS. 

I use simplify3D to slice but the difference between the theorical and real printing time is very different. For exemple, if simplify shows me 3 hours to print, the creatr will print the piece in 6 hours. I tried to modify many fonctions but anything make it. The real printing time is always twice the simplify time. I also have a Big Builder and with this printer, the theorical and real time are similar (5-10 minutes difference but that is normal). 

Do you already have that kind of problem? Do I do something wrong? 

Thank's in advance for answers


I got the same issue as you defined above but my time is not 2 times the amount. Something like 20% of the time. I print larger objects that take around 30hours (simplify3D) but in the end it took 36hours.  

I tried smaller objects but it still had a deviation from what the programs shows.


yes calculated time is very wrong. I also tried to find a correction factor to calculate correct time I come to about 1,2 or 1,25x the calculated time.

I wanted to make a timer to measure build time and stop automatically when done. and maybe turn off printer too.
