Print time estimates unavailable with cura gcode
-
It probably means that they have changed or removed the comments in the gcode file that describe the filament needed and other important parameters that RRF needs to work out the estimates. Post the first and last 50 or so lines of your gcode file (the ones that are all comments) and we should be able to confirm thus.

That is indeed the problem: Cura is not generating the comment saying how much filament is needed, that all other slicers (including the "old" Cura) generate. Also they have made the layer height setting more difficult to parse. So the only estimate that RRF is able to generate is the one based on file size.
-
What are the comments RRF uses to calculate the estimates?
I found that when I use Simplify3D to slice different parts of the model with different layer heights, the total layers shown is incorrect.
I haven't check if this is caused by S3D or RRF, will look into the gcode tonight. -
So the only estimate that RRF is able to generate is the one based on file size.
But the web display doesn't even show an estimate based on file size. It shows n/a for all 3 estimation methods.

If it still shows that after printing a few layers (can you confirm?), that sounds like a bug. Please put a smallish gcode file that reproduces the problem somewhere where I can get it (e.g. Dropbox, Google drive, MS OneDrive etc.), suitable for either a delta printer with 280mm printable diameter or a Cartesian printer with 200x200mm print area.

Sorry, only just noticed your last reply, I will provide you with a file.
I have contacted the Cura devs re the lack of total filament used info in the current gcode and, yes, the current Cura no longer provides that info for non-ultimaker printers. I will work on putting that back in so I would like to know if you have any preferences in the format of the info (same as before, or different) and also I wonder about whether something different needs to be done for multiple extruders? For ultimaker printers, the current Cura outputs lines like this:
;MATERIAL:3748
;MATERIAL2:0I assume those are mm not m!
Can the Duet just use that format? If so, I can get the same info output for non-ultimaker printers.

Here's a gcode file produced by cura 2.3.1

I have now modified Cura to output the total filament used in a similar fashion to how Cura 1.15 did and that appears to work as expected. What's interesting is that it also fixes the estimate based on file progress as well as the estimate based on filament usage so my guess is that when the filament usage estimate is broken, it also breaks the file usage estimate.
Anyway, if you add the following line into the head of the above example file, the file and filament estimates work OK. However, the layer time estimate is still broken.
;Filament used: 0.173359m
-
Just letting you know that the next release of Cura (2.4?) should include the filament used comment in the style shown above.
-
Great work! I really missed print time estimate based on filament used in 2.3!
Thanks a lot!
