Help understanding the "new" reusrrect.g

modl

Hi everyone

A one week print failed 80% in because of a "G2 out of bound" error. i'm not sure how it happened considering a whole support has been printing at the exact same spot for the whole duration of the print. Anyway, it didn't generate a resurrect.g but i have safeguards and can pinpoint accurately enough where the print failed (layer number global, and last reported position registered by daemon.g). So i will try to resurrect this print by editing the resurrect.g template which i did in the past when I was on 3.4.6. I'll add an M564 S0 and see where it goes. But things have changed a lot with 3.5.x and I'm seeing a whole lot of gcode command sequences that seem to be repeating and some that are more CNC oriented.
-My machine is a rather simple corexy dual extruder 3D printer.
-->What parts could I get rid of after resurrect-prologue have been called ?
-->What are the X and Y arguments for in the first M26 call ? couldn't find them in the reprap gcode reference.
--> M204 P50000 T50000 is extremely far from my settings in config.g (see at the end of the post for reference)

Thank you very much in advance
Best

@modl said in Help understanding the "new" reusrrect.g:

-->What parts could I get rid of after resurrect-prologue have been called ?

That's hard to say, it depends on what needs to be restored, which depends on your configuration.

-->What are the X and Y arguments for in the first M26 call ? couldn't find them in the reprap gcode reference.

If a G2 or G3 move was interrupted then they are the coordinates of the centre of the arc that was being printed (e.g. X and Y if the XY plane was selected). In this case there will also be a P parameter, which is the fraction of the arc that was completed.

--> M204 P50000 T50000 is extremely far from my settings in config.g (see at the end of the post for reference)

Those are default values. They are deliberately set higher than typical values set in M203 so that the M203 limits will be used unless the slicer emits M204 commands in the GCode file.

modl

@dc42 Thank you for your reply !
I guess i could either delete or ignore M204
There is indeed a P parameter after the first M26 call, that makes sense. But the second call only gets an S parameter
My question is , why is this sequence repeated twice with slightly different parameters?

M83
G94
G17 
M26 xxxxxx
G1 P0
M204
G21 
M596

I guess there is no command i need to delete as they won't get in the way or are default from config.g (M596 M486 G54 G21 G94 G17) but the repetition of G1 instructions to the same point seems odd

dc42

@modl good question ~~that looks redundant to me~~ it's once for each motion system.

modl

@dc42 OK I think i understand. It looks like it's not relevant for my setup as the motion system is the same for both extruders as they share the same tool head ? But I don't necessarily need to remove one sequence or the other as they are, at worst, harmless ?

dc42

@modl you can remove the sequence that starts M596 P1 if you are not using the second motion system.

modl

@dc42 I ended up removing M596 and M486 instructions indeed, they were causing issues in my case, where i was restarting the print with T1 instead of T0. Thank you for your replies
