DWC print timer bug/oddity and cura gcode error

osterac

Hi all,
Running a duet 2 wifi rrf/dwc 3.3.
So I noticed a weird thing with the print timer that shows estimated time left. Specifically, the one that shows the slicer estimate. First, it starts the timer before the printer has come up to temperature (before start gcode is finished). This can make the estimate wildly inaccurate. Second, when the print ends, the timer resets and starts counting down again. The other timers don't do this, but for some reason the warm up time indicator shows "n/a" when I would think it should show the warm up time for the last print? I've had issues with the warm up timer being inaccurate actually, come to think of it.

As for the cura thing, ever since updating to rrf/dwc 3.3 (from 3.2), whenever I print something sliced by cura 4.11 I get this error at the end of the print:
Error: in GCode file line 10696 column 10: M84: expected number after 'E'
The line number might vary, I'm not sure. It's a minor annoyance, the print comes out fine, but it seems strange. I'll attach gcode.

Anyway, these are just a few things I've noticed. Nothing urgent, but I thought you might like to know.
Thanks for all the great work you do.

@osterac the second one about M84, you need to edit the end gcode and add a 0 after the E so the firmware knows which extruder to turn off.

Take a look at your end g-code from your slicer, I think you will find here the M84 (Stop idle hold) this command is normally a Configuration command if you set M84 S35 in your config.g then all motors going to idle mode after 35 seconds inactivity.
Or edit your end g-code and add the extruder number also M84 X Y E0

Second, when the print ends, the timer resets and starts counting down again.

Now I know what I have forgotten, this Problem persists at firmware 3.4.b5 too

@siam
You're right, it was my end gcode. I had it set up to turn off all steppers but Z, because my bed used to have a problem where it would sink to the bottom after the power was cut to the stepper motor. I put a lead screw with finer threads in to fix that so I guess I can turn the z axis off now as well - though I might leave it on so I can lower the print away from the nozzle to remove it more easily if need be.

Is this an issue you notice with a specific slicer print time reports?
