Duet reporting inaccurate percentage.

I've just run that file in simulation mode. It finished just after reporting 88% complete with >1m of filament remaining. This suggests to me that either RRF is accumulating filament usage incorrectly, or that PrusaSlicer is reporting incorrect filament usage for the particular options you are using.

I think that RRF may be being confused by wipe during retraction. Please can you try running that print in simulation mode and check that you get the same results as me (or run another file if you prefer, and note the % complete figure it reaches just before the end). Then slice that file again, turning off wipe-while-retract. Simulate that file and see if the behaviour is different.

@dc42 running that .gcode I linked earlier shows a correct readout in simulation mode; reaching 100% as expected. I am referring to the DWC %

EDIT: i ran the file that finished at 55% from earlier in simulation mode, and it showed proper percentage up to 100%

Strange, when I ran your file in simulation mode (using RRF 3.01-RC7) it definitely jumped from about 88% to 100%.

I am fairly sure that wipe-while-retract is confusing the filament used accumulator, but I don't know if that is the only issue here. Can you re-slice one of your prints with wipe-while-retract disabled and see if the problem goes away?

This is now fixed in the 3.01 source code and in the firmware binaries at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0.

@dc42 disabling wipe while retract solved it! Although am i able to use 3.01 with a duet 2 wifi board?

Board: Duet WiFi 1.02 or later
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.05.1 (2020-02-09b1)
Duet WiFi Server Version: 1.23

Yes you can, however you will need to make substantial changes to your config.g file if you do upgrade. See https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Summary_of_what_you_need_to_do_to_convert_your_configuration_and_other_files for the details.

The fix will probably make it to RRF 2 eventually, but not until it has been in RRF3 long enough for me to be certain that it has no unexpected side effects.

Turbo

@dc42 Got it, thanks. I always assumed the RRF 3 would only work for Duet 3 boards and later. IDK Why

Turbo

@dc42 After updating to RRF3.0 RC7, the issue is still present it seems. i have a current print about 50% done, however, the DWC only shows 6%, and i can watch it go up and down in percentage, which i dont think is supposed to happen. The object is consistent all the wey to the top, so there shouldnt be any large discrepancies that would affect %. This is with wipe while retract is on, because it does affect my print quality noticeably.

Yes the bug is present in the 3.01-RC7 release, but fixed in the post RC7 build that I linked to earlier.

I'm not sure if this issue is connected with my recent move to RRF3.3b2. Since I did, I've had a number of prints telling me they are over 100% complete. Querying the forum I found this thread, and the detail that completion calculation is based on GCODE-embedded filament usage.

In the GCODE file I see:

; filament used [mm] = 13125.43

In DWC, I see this at the end of the print during my cool down phase:

and

The layer count is off, but the filament consumption seems to suggest the reported job completion level should be 99%, not 144.7%.

To add to the mix, I'm also testing ArcWelder, so the GCODE has G2/G3 commands scattered throughout.

One for @chrishamm.

@spoonunit Please share the full G-code file and I'll have a look.

@chrishamm here you go

seq26.gcode

SpoonUnit

It's even more exciting in simulation mode - getting to about 354% before then completing and setting itself to 100%.

dc42

@spoonunit, please share your config.g fie.

What sort of mixing extruder do you have? In your M567 command(s), is the total mix ratio 1.0?

SpoonUnit

@dc42 I'm not using mixing at all. There are no M567 commands.
