Improving Marlin print remaining time

[woofy 12]

No applogies for putting this in the Cura section.

With 14.01, print time prediction is spot on (as far as makes no difference), Marlin however is hopeless.

Cura must be calculating, layer by layer, the print time. Could this be embedded in the Ultimaker gcode so that Marlin could read this and report the remaining time with the same accuracy.

Daid, is it possible?

The UM2 is already using this estimate (also shown when you select a file), however, in the math something goes wrong while printing. Especially near the end of the print it will suddenly show 6 hours.

Haven't found the time to look into it yet.

Hi Daid,

Marlin reports the Cura estimate at the start of print. What I meant was if Cura embedded its remaining time estimates in the gcode near the z-movement gcode for each layer, then Marlin need not calculate at all. It could just report the embedded estimate on the LCD. It would then accurate all the way through, regardless of the time each layer takes.

I think this would way easier than trying to make Marlin duplicate Cura's calculations. But I do realise this is fairly low priority.
