Running a laser job on 3.4RC2. Currently showing as being 130% through the job

here's my gcode file. change the file extension. I am using .gc as thats the output from lightburn

@jay_s_uk On genuine Duet boards I cannot reproduce this in standalone or SBC mode with the file you provided. See my previous explanation what could cause this.

[jay_s_uk]

@chrishamm I'm sorry, but i disagree that it doesn't affect duet boards.
Yes, that original issue raised its head on a Fly-E3-Pro but I have since setup a bench test using a duet 3 mini and have got the same issue.
The job ran to over 700% progress before finishing at 100%

@jay_s_uk When I saw this (on a Fly-E3-Pro) I determined that it's calculating on the basis of the previous file length. That is, it is calculating progress as (current file position)/(length of previously printed file). Does that match what you are seeing?

[jay_s_uk]

@achrn it could be, although I ran the 1st job I tried 3 times and didn't see anything. I then ran the 2nd job twice and didn't see anything. But the 3rd file went over straight away. And to reiterate for @chrishamm all of this further testing was with a duet 3 mini

[dc42]

@jay_s_uk @achrn are both of you running in SBC mode?

[jay_s_uk]

@dc42 I'm running standalone and if @achrn is using a fly-e3-pro, he will be too

[dc42]

@jay_s_uk thanks, that tells me where to look.

[mrehorstdmd]

I regularly see numbers like 850% complete (when the file is only partially finished) on DWC on my sand table that has no extruder. I think the first pattern file I run after booting the board shows a correct % complete value, but running a second file (or more) starts showing silly numbers.

I'm running Duet 2 WiFi, and last updated firmware about 4 months ago IRIC.

@jay_s_uk said in Laser Job showing more than 100% 3.4RC2:

Yes I am (both using a fly-e3-pro, and standalone).

Same as @mrehorstdmd, mine is a sand table so no extruder (and no extrusion commands in the gcode). On mine, the first pattern file I run stays at 0% progress (as if the preceding file was infinitely long).

[dc42]

@mrehorstdmd does it occur when running a large GCode file, when you previously run a smaller one? Some users with this issue think it is using the file size from the previous job as the 100% mark.

[mrehorstdmd]

@dc42 That's entirely possible- I often run a relatively small erase pattern file followed by a much longer pattern file. I'll try it and see.

[mrehorstdmd]

@dc42 I've been trying to make it misbehave for the last couple hours and it's not doing it now. The next time I see it I'll make a note of what I was doing.

[dc42]

@mrehorstdmd thanks for trying.
