Time Calculation in Cura

[celso-santos 11]

There are two questions that I would like to raise:

1. Cura time calculation is a mess. My latest example was a part that I designed yesterday. When I generated the g code Cura informed me that U2 would take 30 hours to print the part. In fact it took 17 hours.

Why that happens? Can Cura be more...sorry...acCURAte?

2. Sometimes I leave my part printing and go away. I'd love to have a setting that makes my machine turn off after a part production is finished. Can that be made?

I only have a UM1, so I am just assuming the UM2 has similar limitations but...

1) Cura doesn't know the acceleration and jerk settings on the printer, so that might be part of the discrepancy. (I imagine this is also true on the UM2.) There is also the possibility that your print speed is turned up on the UM.

2) You can put whatever code you want in the start/end gcode. By default, it should disable the steppers and turn off the heat. I don't think there is any software method for powering down.
