Solved [SBC] Error: M140 has thrown an exception:
X3N07 last edited by dc42
I recently added a SBC to my Duet mini 5+. In standalone mode it printed perfectly fine with no issue. But now I cannot print anything. It still does homing at the beginning of the print, but at the time the printer should be heating up, it displays the following error message:
Error: M140 has thrown an exception: [ArgumentException] Failed to serialize code.
When I switched from standalone to SBC I did not change any configuration files.
It is also strange that a file printed once without error, and when I tried to print the same file again, the error occurred.
I am aware that there are two similar topics, however, these did not help me.
I switched back to standalone mode and everything is working perfectly fine. What could be the problem? Thanks for your help
Did you go through the software update process on the Duet Pi installation?
Sudo apt update && sudo apt upgrade?
When in SBC mode the SD card needs to be removed from the Duet itself.
Can you setup SBC mode again, and this time send M122 after you see the fault and post it here?
@Phaedrux Yes, I did the software updates on my Pi and removed the SD card from the Duet.

Can you share your config.g and the first 50 lines or so of the gcode file being printed?

And this are the first Lines of the Gcode. This is actually not the first line but the 337th. Line 1 here is the 337th line in the Gcode file itself. But the lines 1-337 are only comments. I think they are for the preview image. I have removed them once, but it made no difference.

Is that a finished sliced file from cura? It looks like the placeholder values haven't been evaluated to actual numbers.
M140 S[first_layer_bed_temperature] ; set bed temp
[first_layer_bed_temperature] should be replaced by the slicer to the actual number value chosen for the bed temp. If it's not doing that either the placeholder text is incorrect, or something is stopping cura from replacing it, maybe a bug?
At any rate, if you pass
M140 S[first_layer_bed_temperature]to RRF as is, it's not going to like that, it expects a number.
@Phaedrux Yes, this is a sliced file from cura. Last week I changed M140 S[first_layer_temperature] to my target temps, but then I got a new error. Not M140 but M190 S[first_layer_temperature]. But I just wasn't smart enough to change that too : So now I did that and had several other errors:
Error: in GCode file: M140: temperature too high for heater 0 Error: in GCode file: M190: temperature too high for heater 0
But despite the errors it did print.
The "[first_layer_temperature]" seems to be the problem. But why can I print the exact same gcode file in standalone mode without any problems?

I discovered that I also get error messages in standalone mode:
Error: in GCode file line 1403 column 11: M109: expected number after 'r' Error: Bad command: mperature] Error: in GCode file line 1404 column 11: M190: expected number after 'r' Error: Bad command: mperature] Error: in GCode file line 1397 column 11: M104: expected number after 'r' Error: Bad command: mperature] Error: in GCode file line 1398 column 7: M140: expected number after 'S' Error: Bad command: mperature]
But they are probably only reported and then ignored, because the print continues normally.
The line numbers don't match the above gcode, because that was a different print.

It's handling garbage inputs differently.
I think the problem is that you're not using the right replacement terms for Cura. Cura uses curly brackets for one thing. Maybe you've got them from Prusa Slicer?
Here are curas
Here's prusa slicers
@Phaedrux I found my mistake. I thought I had no start code for my extruder in cura. I even looked it up. But cura didn't display anything.
Turns out I did have one.
However, the start code was not displayed unless I clicked on the input box.
And in my startcode there were the bad gcode commands.
Now that I removed them, the gcode file looks normal again and everything works as it should.
