NEW PROBLEM WITH 1LC CARD

Gianluca

Excellent suggestion the LEDs.
I actually have 126 RGB LEDs on the top of the chassis, and 3 RGBW LEDs on the stealtburner, but unfortunately they are both connected to the 6HC motherboard (LED port + io.8) not in 1LC.
The 126 LEDs have always been there, while the LEDs on the extruder have only recently been using the following management macro: https://github.com/Exerqtor/Voron/tree/main/Firmware/rrf-macros/sb_leds.
This evening I will try to remove the configuration of all the LEDs and start the print again.
I attach config.g and daemon.g

@Gianluca if the LEDs are on the 6HC, they won’t be causing the out of memory problem on the 1LC.

I’ll ask @dc42 to look at the M122 report.

I also did some tests in stand alone mode, and the problem remained, I attach console report.
I made a small print and before finishing it stopped permanently and now the 1LC card no longer responds, it seems broken.
I purchased the card in April 2023 and until yesterday it always worked well.
What can I do?

@Gianluca show us some photos of the toolboard, and the wiring connection for CAN (both ends).

jay_s_uk

@Gianluca can you try disabling the filament monitor?

dc42

@Gianluca also as you are using 3,5rc firmware please try the new firmware binaries at https://www.dropbox.com/scl/fo/p0136wx04h8xf6ejwdnn9/h?rlkey=efrfwyb6o5tqid11gustz3uvy&dl=0.

Last day, I replaced the CAN cable with a new one and the board started working again.
I made a print for 36 hours, but reported the "Expansion board 121 stopped sending status" error about 20 times, still completing the print.
As suggested I installed the R3+ on the 6HC, and everything went fine, then I installed the "Duet3Firmware_TOOL1LC.bin" file on the toolboard and it did not complete the update, blocking the card.
Now the 1LC is no longer seen on the mainboard.
How can I restore the toolboard, since the toolboard is no longer seen by the motherboard?

Try a factory reset

Yes, I already tried, it doesn't work.
Attempting to install RC3+ knocked out the toolboard.
When turned on it flashes 3 quickly and then 5 quickly for 3 times, then the red LED is off.

droftarts

@Gianluca See here for the LED flashes: https://docs.duet3d.com/User_manual/Machine_configuration/CAN_connection#led-behaviour-and-error-codes

Number of flashes:
3 Bad firmware CRC
5 The bootloader requested firmware but the main board reported that it didn't have the correct firmware file

It looks like the firmware upload failed, and the main board can't find a the correct firmware file. Download the 1LC firmware file again, and upload it to your Duet mainboard again, to the /firmware folder. Then reset the 1LC. Hopefully it will find the firmware and update, then.

@droftarts

Unfortunately what was recommended did not unlock the toolboard.
I tried both in SBC and in stand alone mode.
Would it be possible to send the card to technical assistance for repairs under warranty?
The damage was done following DC42's instruction.
I also purchased a new 1LC toolboard from DHM Compass Project yesterday...

3 times is normal after telling the board to update, it just means that board doesn't have any valid firmware on it. 5 times means the Duet main board reported that it didn't have the requested firmware. So as Ian says, download the file from Github and upload it to the Duet again.

Yes, that's exactly what I did last night, both in stand alone mode and in SBC, but the firmware doesn't load.
List of tests step by step:

downloaded the file Duet3Firmware_TOOL1LC.bin ver. 3.5.0 RC3 from Gitub
copied the file into the firmware directory
turned off the printer
turned on the printer by holding down both buttons on the 1LC board for 5sec, then released. (I also tried 1 second and also keeping them pressed all the time)

Result: no firmware loaded, 1LC card always unusable.

If you give me a detailed procedure, I can try again...

Gianluca

Sorry for insisting, but I have a 1LC board that is stuck after trying to install a firmware provided by the Duet team.
Unfortunately factory reset using the two buttons doesn't work.
Should I throw the card in the trash? Is there anything else I can try? Is there a warranty for this type of problem?
Thank you

Phaedrux

Alternating 3 and 5 flashes then the main board should put a message in the DWC console saying that a firmware file was requested but not found. Check the DWC console while the 1LC is trying to load firmware and giving those flashes to see what it's requesting as missing.

Thank,you, this weekend I'll make further attempts and check the messages in the DWC console.
I will try again in both, SBC and stand alone mode.
In SBC mode, is it recommended to power up the toolboard after the system is already running? (in SBC mode, the boot is very long...)

Phaedrux

I'd say it would be best to test with as minimal a setup as possible, so try standalone.

Gianluca

SECOND 1LC CARD BRICKED AFTER UPDATE
This morning I updated the printer firmware to go from 3.5 RC3 to RC4 and also the second 1LC card is now unusable.
The update process stopped at 96% (see photos). After 30 min i have reboot the printer and now M122 B121 gives no response.
Can I get warranty assistance for at least (second) toolboard? I don't want to buy a third one!!
All attempts made to unlock the first toolboard did not work.
Thank you

Is this the same can cable as before?

dc42

@Gianluca what happens if you connect just one of the non-functioning tool boards to the CAN bus and hold both buttons down while powering up? What sequence of LED flashes do you see on the tool board?
