Print Time Estimation wrong

Daid can say for sure, but I think it's because it doesn't take into account acceleration factors which mean that the average speed for every move is lower than the nominal print speed - and for short segments it can be quite a lot lower.

Kisslicer allows you to specify what acceleration you are using, in order to better calculate print times. It's not perfect, but it's usually pretty close.

    Illuminarti is spot on here. The times calculated in Cura do not account for acceleration, which can cause anything between a 20% and a 100% error. It's pretty hard to estimate printing times, unless you fully simulate the machine (which I might do some day, if I have one of those mad-coding days)

    I am disappointed Daid.

    So Daid if you just multiply the estimated time by 1.6, the estimation error will be about +-30% or less. I am assuming the uncorrected calculated times are always less than the actual ones, as it happens with NetFabb.
