Layer chart not updating in 3.2

Jobie52

I have just upgraded ReprapFirmware from version 2.xxx to 3.2 (2020-01-05), DWC 3.2.0, WiFi Server 1.25. I made all the changes to config.g. the printer is performing as before.
However, the layer chart stays blank, the first layer time is the same as the total print time.

The layer chart worked perfectly in the 2.XX version. I am using Slic3r 1.3.0 as before, nothing changed here.

Can you confirm that you have DWC 3.2 installed?
Can you provide the output of M115 to confirm the firmware version?
Can you also provide a sample gcode file?

Herewith screenshots and code.

I don't see any obvious reason in the gcode example why it wouldn't show the layers. Sometimes having some Z moves in the start and end gcode can throw it off, but you don't have anything odd.

Thanks for looking at my problem.
I just noticed that the job information box has the layer height at "0.00mm". Where does DWC get this info from?

The last 13 hour print I did the chart did not update at all.

Slic3r 1.3.0

maybe its time to update to prusaslicer 2.3 ?

does reprapfirmware rely on the slicer to output some code/comment on layer change?

yes as far as i understand it.
how else would it identify the slicer that sliced the g code?

yeah I get that it reads the comment for cosmetic reasons (slicer name, estimated total print time), but I didn't realize that it relies on some comments for functional reasons (even those the I guess the graph is still cosmetic).

I don't remember if Slic3r supports variables, if so @Jobie52 you may try to add

;LAYER:X

at each layer change, where X is the current layer

too

We see the same issue on Duet2 with latest firmware installed, Layer time is not updating.
The gcode we tested definitely worked previously.

I think if you have lines like ; layer 42 in your gcode the duet uses this as indicator for layer change.

Ok, now I am flummoxed, restarted Repetier host and sliced a new part using slic3r, now the layer chart is working! The job information box now has the correct information.

@matt3o - the coded generated already has a comment " ;layer_height = 0.3" this comment was also present in the "non working" code.

Thanks for all the comments.!

you need the layer number for each layer (not just the layer height)... but anyway it works now, so everything's fine

Thanks, will do

Guess I spoke too soon. Problem still persist. I have updated to PrusaSlicer 2.3 as suggested by @Veti. No difference I cannot understand why it worked in firmware version 2 and not in 3.

Oh well, have to live with it.
