files suddenly taking a long time?

I have been successfully using Repetier for months, printing the same files. They usually take 7-8 minutes, how after I slice them they say they will take 3-4 hours? What happened? I did not change any settings and am confused at how the same file has changed in print time.

  • Who says this? gcode at the end or host time computation? Only reason for wrong time in host computation would be using slower feed rates for printing. Have a look at the Fxxx parts where speeds get set.
