Marlin Time Calculation.. .

[woofy 12]

. .is way off.

Cura estimates my current print to be 10Hrs 33mins.

Its been running about 90mins so far and my UM2 reports another 26Hrs print time.

I'm printing a box - base and side walls. The first few layers, the base of the box, are very time consuming but it will speed up layer times when it gets to just the side walls.

Could it be that marlin calculates based on layer times?

According to daid it is the file size and not layer number:

I think the very first variable: printTime might have a bug where it includes the warmup time of the bed and maybe even the time while left in the tune menu before the print starts.

Ah!

Thanks for pointing to Daid's post, that explains it.
