@dc42 it's any store where can i buy a version with 3.1.1 uploaded or the previous version of board? Thanks

@dc42 Hi dc42,
That's not the first duet3hc expansion board that i'm using, i've uploaded the firmware very well in many boards.
With the last version of board( V1.01) is not possible to upload this firmware.
Did you think that is a problem of this single board or the new version of board?
Thanks

@phaedrux Hi,
I'm starting from this situation:

All averaging filters OK

the boards works well.

confirm to update

the Expansion board diag LED don't blink and don't response to the mainboard.

@Phaedrux
For this moment i'm not planing to update this firmware, i understand that is a good update but for now the timing don't alows me. I don't understand why this board is not retro compatible? There is any reason?

@dc42
Hi,
This error is generating when i try to upload the official release. First at all i want to install the official release then i proceed with the customized firmware.

@danielpetrea Anyone who can assit me to solve this problem? Thanks

@jay_s_uk i'm using this firmware with other machines and works well, i don't encountered CAN problems with 3.1.1.
What's the difference between Duet3 EB 3HC v1.0 and Duet Eb3HC v1.0.1 ?
Thanks

@jay_s_uk said in Duet3 Expansion Board 3hc blocks during downgrade:

s Bad firmware CRC

do you know what should be the cause to this error? i tried to install the firmware 3.1.1 with hard reset procedure (all swich off and then power on) but don't upload this firmware

@jay_s_uk after uploaded the bootloader 1.3 on expansion board 3hc , the status led blinks 3 times.
Do you know what this is meaning? thanks

@jay_s_uk i uploaded the bootloader 2.3 but when i upload firmware 3.1.1 the expansion board don't work (led status not blinking).

@jay_s_uk @jay_s_uk what's the procedure to downgrade the bootloader? i tried to copy the bootload to sys folder and type M997 B1 but don't update anything

@jay_s_uk said in Duet3 Expansion Board 3hc blocks during downgrade:

There shouldn't be anything that massively changes a config between 3.1.1 and 3.4 so what do you think wouldn't work with it?

Hi Jay_s_uk,
Thanks for reply.
I understand but it's not only a custom config, it's a custom firmware so i need to use the version 3.1.1.
I can downgrade the main board from 3.4 to 3.1.1 and works very well, the problem is when i downgrade the expansion board from 3.2 to 3.1.1 and i don't understand the reason

Hi,
I have bought a new duet3 with a duet3 expansion board 3hc. I installed the latest firmware 3.4.0 on both boards. The comunication works very well.
I need to install the firmware 3.1.1 because my printer has a custom firmware based on 3.1.1 version.
I have tried to install the firmware sequentially from the firmware 3.4.0 to 3.1.1.
First i update the expansion board firmware then the main board.
It's works very well from 3.4 to 3.2 then , when i update the expansion board from 3.2 to 3.1 (Duet2and3Firmware-3.1.1.zip package files) the expansion board stop working , and the status led don't blink , it seems like blocked.
Then to restore the board i have to do the hard reset (4 switches to OFF state ) and upload 3.4.0.
I don't understand what is the cause for this problem.
Can you give me a hand to downgrade the expansion board from 3.4 to 3.1? thanks

@Phaedrux yes , and the board has rebooted

@Phaedrux I tried to update with this firmware but the problem persist...

@jay_s_uk
Yes, i have the jumper like your photo

I tried to update the firmware to 3.1.1 but the boards not connect. Connect for some seconds and then disconnect. i send you a photo of the 3HC!!

@jay_s_uk said in Duet 3 Expansion looses connection while printing:

Board EXP3HC firmware 3.0beta1 2019-10-28b1

Mainboard RRF_3.1.0
The M115 B1 returns me
Error: M115: Response timeout: CAN addr 1, req type 6024, RID=24

I noticed that when i restart the printer , the expansion board comunicate for about 5 seconds and then stop the comunication.

Hi,
I have a printer with a duet3 6hc and a duet 3 expansion 3hc v1.0. During a print the expansion board lost connection and the print stopped(i have the heaters connected on the expansion board). I tried to restart the printer but the problem persist. I tried also to change the canbus cable but nothing.
What should i do?
Thanks

HI,
I'm using a duet3 6hc with duet3 expansion board. I need to use the motor stall detection with axis that are on the expansion board, but don't work.

T0
G92 U0
M574 U1 S3
M913 U70
M400
M915 U S4 F0
G1 H1 U-50 F3000

I tried this macro with the U axis connected to the mainboard and works, but when i connect the U axis on the duet expansion board this feature don't work, the motor stall are not detected.

Thanks,
