Restart a print after fault pause and timeout?

[Legrand]

I was printing a rather large print at work over he weekend, and after about 40 hours of printing, the printer had a heater fault. Three hours later (10800 seconds), the console reported that the print was cancelled due to the un-cleared heater fault.

I've read that you can resume a print using resurrect.g, but when I try to use M916 to reactivate, I receive an "unsupported command" error. Is there any way for me to salvage this print, or am I dead in the water?

HAd the same Prob with a heater failure.
Readon why i couldnt restart it, is a missing resurrect-prologue.g file.
a resurrect.g file is there...and documentation isnt very clear about how to get the resurrect-prologue.g

Or work that feature only with voltage drops?

[Legrand]

I added the resurrect-prologue.g file to the sys folder when I was trying to get it restarted this morning, but it didn't make any difference.

See https://duet3d.dozuki.com/Wiki/Setting_up_to_resume_a_print_after_a_power_failure.

I did that.
The documentation says "... you can use command M916 to resume the print from where it stopped."

As I stated above, I set up the file sys/resurrect-prologue.g, but when I sent the M916 command, I got an "unsupported command" error.

I was guessing that this was because I didn't catch it in the first three hours?
Is there some other way to restart the print?

Are you running latest stable firmware i.e. 1.21?

[Legrand]

Yeah, 1.21.

[dc42]

In that case, the "unsupported command" error will have included the G- or M-code that isn't supported. Please provide the full error message.

[Legrand]

M916 isn't supported. It's saying "M916 command is not supported".

@legrand said in Restart a print after fault pause and timeout?:

M916 isn't supported. It's saying "M916 command is not supported".

It sounds as if you are not actually running firmware 1.21. Please send M115 and report the response.

[Legrand]

Here's the relevant info:

[Mysta]

@legrand Go to 'G-Code Console' and enter M115

[Legrand]

It's right there.... in my last post... the third picture. I'll post it here again, but this time not as a picture?

It's because you are using an older Duet, which doesn't support M916 because the older Duets don't have power fail detection. Try this instead:

M98 Presurrect.g
