Help, extruder don't work anymore.

@Julien30 Extruder drives are assigned numbers in the order that you define them in M584. So as you have M584 X40.0 Y41.0 Z42.0 E0.4:0.5, then extruder 0 (D0) will be the one connected to drive 4 on the main board and extruder 1 (D1) will be the one connected to drive 5 on the main board. When testing, don't forget to send M302 P1 to allow cold extrudes.

Hi @deckingman
Ok I was not thinking it work like that. Thank you.
For the M302 P1 I always use it when I want to make some test but for that I have done a macro to send it and allow cold extrusion.

@Julien30 what firmware are you running?

I have just seen that the firmware version is in the configuration general of DWC so here it is.
The firmware version is :

3.5beta2 (2023-02-08)

@Julien30 theres a bug in beta 3.5b2 where cold extrusion doesn't work. upgrade to 3.5b3

Julien30

@jay_s_uk @deckingman

Thank you so much,
I change the Firmware for the 3.5 beta 3 as @jay_s_uk said and I've made the modif as @deckingman said.
Now it's work perfectly.

Thank you.

@jay_s_uk
Well maybe a little to fast.
After I have done the modifs I only try to move the extruders and It work well.
But now the 3 motors for XYZ axis who are pinned command to 3 cards EXP1XD don't want to move.
They worked when the Firmware was 3.5 beta 2 (2023-02-08). Do you think this issue come from the firmware?
Because if it's the case I switch to 3.5 beta 2 and don't allow cold extrusion. I prefer make the heater go to high temperature for extrude than the XYZ can't move...

@Julien30 i don't think so. i'm running 3.5b3 on one of my machines with success. did you update the firmware on the expansion boards as well?
are you homing them before trying to move them?

Julien30

@jay_s_uk
Yes I homing them before.
Can you remember me the way to update the firmware on the expansion boards please.
Because I've downloaded the firmware in the SD card of the MainBoard and equally charge files from DWC.
All the time the 3 EXP boards are connected together and to the Mainboard with alim ON.

jay_s_uk

@Julien30 just upload the expansion board firmware for 3.5b3 https://github.com/Duet3D/RepRapFirmware/releases/download/3.5.0-beta.3/Duet3Firmware_EXP1XD.bin

Julien30

@jay_s_uk
Yes It is the file that I downloaded and upload on the SD card in plug it in my computer. Then reinstall the SD card in the Mainboard and afterall upload by DWC the file with th charge files button

jay_s_uk

@Julien30 why unplug the SD card? you can do all updates through DWC. That way it'll then prompt all the appropriate boards to update.
Either reupload that file or send M997 B40 and so on for each board

Julien30

@jay_s_uk
Oh right, It's more easier.
I've done what you suggest and it work perfectly.
Thank you very much
