Hi,

i'm printing an object that cura told me the U2 should have print in approximately two hours. But now (two hours later)... it still tell me that left two... and the print is almost at the half.

Cura has committed an error or is something else?

Thank you.

    It's a long-standing and well-known bug in Cura, due to the fact that it's actually quite complicated to figure out how long a print will take, since the print head doesn't move at a constant speed but, rather, speeds up and slows down for (some) corners.

    Daid has said in the last few days that he's working on improving it, so i expect there will be fixes in an upcoming release of Cura.

    Yes, next release (out next week if nothing goes wrong) will feature updated time estimates. Worst I had so far was that a print of 2 hours and 30 minutes was estimated as 2 hours and 40 minutes. Which is not too bad. The new estimate is usually pretty accurate or up to 10% worse then the actual printing time.

    Yes, it also effects the estimation of the UM2.
