[REQUEST] Remaining print time start point

[Merlin246]

Hello,

I've been noticing that the file progress time-to-completion estimation is often much higher for short prints, my theory is because of the initial heating time in the start gcode.

It would be nice to have a command that you could put at the end of the start gcode (something like M73 P0, of which the P command isn't used in RRF) to start the time-estimation from that point onward so the time-per-command isn't tainted.

I may be completely off-base if the time estimation works in another way but alas.

Thanks!

@Merlin246 the estimation code tries to leave heating time out of it; so heating up should not affect the estimate if that code is working as intended.

I suspect that a more important factor is that the first layer is typically printed at a slower speed than subsequent layers, so the rate of filament consumption is lower at the start than for the print as a whole.

@dc42 in DWC, the time remaining counter derived from slicer print time estimate starts when you start the print and heater time is included.
