Slicer based time estimation
-
Hi,
I'm wondering how the silcer based time estimation in DWC works.
I think that it uses the name of the gcode file and takes it, but I would like to know that for sure and use this estimation at my workflow.
For example I slice something with prusaslicer and let it add the time to the file name.
It will generate something like Testprint_24m52s.gcode and takes that time as the slicer based estimation (I think).
But when I do bigger prints which takes several days, the naming is like Testprint_2d16h27m.gcode.
This file then gives the slicer based time estimation of 1s.Maybe I am lucky, but even on a 3days print the slicer print time estimation is really accurate and just around 10min off.
So I would like to make the slicer based print time estimation to beeing used and shown in DWC all the time.I hope you can give me more insights of how this estimation works, where it is taken from and why it takes _24m52s but not _2d16h27m.
Thanks a lot!

@phil333 the slicer estimates are actually read from comments within the gcode file. Unfortunately, all slicers do this differently and sometimes change the format so this can break. I did a series of tests across a dozen slicers a year back (posts can be found here on the forum) and at that time both standalone and SBC methods to read slicer estimates were improved to support all of them.
Which slicer are you currently using that doesn't show the slicer estimate?

@oliof Thanks for your post.
My last slice was with the latest Superslicer Version.
It generated a gcode with comment, which was not recognized:; estimated printing time (normal mode) = 2d 18h 36m 25s -
What firmware and DWC version are you using?
Can you provide an example gcode file for one of your really long prints? -

This machine is currently running on
Duet Web Control 3.4.0-b5The example gcode cant be uploaded, because its ~43Mb and the limit it 4Mb
But I can show some copied snippets.

@phil333 thanks for your sample. I will fix this in RRF 3.4.0beta7.
