How to change something in file resurrect.g?

DSG

The end of resurrect.g file that was created automatically by system after power failure or planning power off (pause) has some code to move the print head to previous location before power fail. I do not want the print head move up 2mm before resume printing. I must edit the resurrect.g file manually before resume print. How can I config that?
Thanks!

DSG

Anyone can help me?

Phaedrux

Can you post a sample of the resurrect.g?

DSG

My resurrect.g is below:

And the lines that I want to delete

Add some code at the end of it.
How can I figure that? Not modify manually.

Thanks for the sample. What firmware version?

DSG

My board is duet2wifi rev1.04 using firmware 2.03

Phaedrux

I'm not sure if it's related, but there were some changes to the resurrection behaviour in the recently released 2.04 firmware update. Perhaps you can give it a try.

https://github.com/dc42/RepRapFirmware/blob/dev/WHATS_NEW.md

DSG

@Phaedrux the last update 2.04 just fix the select tool before resurrect-prologue.g is called.. I think it is not that I need, but I will try.
Thanks for your support.

Phaedrux

What's in your prologue file?

DSG

@Phaedrux prologue file just
M116
G28 X Y

Phaedrux

Thanks.

Perhaps @dc42 will have some insight.

How are you testing? Manually pausing or pulling the power? If your pausing it, what you're looking for might be in pause.g pause.g

After a skim of the firmware, unfortunately this 2mm lift is hard coded and isn't configurable:

Line 2310 in /src/GCodes/GCodes.cpp:
https://github.com/dc42/RepRapFirmware/blob/2af0feba89833b8631dac6a3e662d4fc13f40410/src/GCodes/GCodes.cpp#L2310

The only way you would be able to change it is to fork the repo and re-compile your own version.

Perhaps you could also add an issue as a request for this to be configurable? No idea how that would be implemented and it may well be too much development for a fringe case.

@DSG what is your M911 command set to:

https://duet3d.dozuki.com/Wiki/Gcode#Section_M911_Configure_auto_save_on_loss_of_power

DSG

@T3P3Tony just turn off the motor X Y and retract follow the guide in wiki.

T3P3Tony

@DSG the guide in the wiki has a Z parameter added in the M911 command, hence why I asked

DSG

@T3P3Tony yes, wiki has guide that but I do not add the z lift code to M911, just turn off X Y motor and retract.

DSG

@littlehobbyshop please tell me how to compiled firmware. Thanks!

dc42

@DSG, can you tell me why you want to delete those 2 lines? Those lines are intended to move the head back to the point where it was when the power fail occurred, without scraping the top of the print.

The firmware build instructions are at https://github.com/dc42/RepRapFirmware/blob/dev/BuildInstructions.md.

DSG

@dc42 the lifting z about 2mm make the resume print not fit with the exist printed object. I have successed with remove lift z code in the resurrect.g not only pause state but also power failure. Have you added this mod in the next firmware version (user can figure the movement of print head)?
