CAN connectivity: Duet 3 MB6HC to EXP3HC

kroybal

I have recently swapped out two Toolboard 1LCs, and my tool distribution board for an EXP3HC board. So far it has solved issues with my x-axes losing steps and resulting in monumental layer shifts. However, upon installing the new board connectivity through the CAN cable has been fleeting. I have followed both the EXP3HC documentation and the CAN basics thread.

I began with installing and wiring (duh) followed with uploading the latest firmware to the DWC. I set all of my DIP switches to off and restarted the my machine by switching the power on and off. The diag LED did not power on whatsoever, upon pressing the reset key and restarting power dozens of times the light finally sync'd with the mainboard and installed the firmware successfully which was verified with M115 B126 command. I then set my CAN address to 15 by toggling all the DIP switches to on and pressed the reset button on the expansion board. This resulted in the diag LED to shut out completely losing its connection to the mainboard.

I repeated the process of toggling the DIP switches again dozens of times, it finally worked again with them all set to off. I addressed 15 again pressed the reset button and let it sit for probably 10 minutes and it finally kicked on and started working. My endstops and motors worked wonderfully and I got a successful test print off.

Heres where the problem begins again. I had to power down to close the box off and connect filament monitoring etc... Upon turning the board on again all progress was lost and I had to go through another 30 minute session of powering on and off and toggling DIP switches till it caught signal.

What detail am I missing? My cable is fine, it is an RJ11 CAN cable that was manufactured and not cut or crimped by myself (obtained with the Duet's tool distribution board). I feel like this board oughta connect and sync up with the mainboard like lightning, I also gotta close the black box and will lose access to flipping DIP switches when I do so.

Can you post diag (m122) from the main and exp board? I wonder if you encountered what I experienced with that combi.

Have you see this thread https://forum.duet3d.com/topic/20713/duet3-6ch-3ch-expansion-board-missing-steps/151?_=1611221812299 ? In short, we managed to reproduce this type of issue, identified the causes, and fixed them in the unofficial 3.3 beta release that we made available at https://www.dropbox.com/sh/wme9k0z86sytg33/AAAT6wrHp2eeJHK-dYoW1Um4a?dl=0.

I have updated the EXP3HC firmware beta at https://www.dropbox.com/sh/wme9k0z86sytg33/AAAT6wrHp2eeJHK-dYoW1Um4a?dl=0. This update resolves the problem on the board that I was testing today.

Please note, the 3.3beta tool and expansion board firmware will only sync with 3.3beta main board firmware. However, even without connecting a main board running 3.3beta firmware, if the fix in the 3.3beta EXP3HC firmware works on your board then the LED on the 3HC board should start flashing as soon as you apply power.

Start by just updating just the 3HC board, and test whether after the update the LED on that board always starts flashing as soon as you apply power (but don't expect it to sync with the main board). If it does, upgrade the other boards too.

So upon updating EXP3HC to 3.3beta and keeping the MB6HC at 3.2 and resetting the power resulted in the LED not blinking upon startup. Should I move forward with running a full 3.3beta?

kroybal

Running 3.3beta on the EXP3HC and 3.2 on the MB6HC resulted in warning message appearing periodically in the console upon a G28 homing command. Both my x-axis motors and their endstops are connected to the 3HC board.

dc42

Those messages are expected because of differences in the CAN protocol between 3.2 and 3.3.

kroybal

@dc42 Understood, I ended up updating to the 3.3beta firmware on both boards. It still requires a bit of patience to let the boards sync up.

jrockland

@kroybal hmm but why 15 ? If you have just a 6hc+3hc shouldnt it be address to 1 ? Or im missing something here

How long does it take? If the fix is working then the LED on the expansion board should start flashing as soon as it received power (as evidenced by the other LEDs on the board), but may take about 2 seconds before it settles down to the slow flash indicating CAN sync. If the other LEDs on the expansion board light up immediately power is applied but the status LED still does not flash until many seconds later, then I need to revisit the fix.

kroybal

@dc42 Following a full update to 3.3beta seemed to be working at this point. It doesn't light up immediately but it flashes about two seconds later (w.r.t. the other LEDs) overall takes less than 10 seconds to sync with the MB. I cannot complain!

Cheers

Edit: I should have bit my tongue, I tried another time and the LED failed to turn on all together following power up. It has been about a minute and no light.

@kroybal hmm but why 15 ? If you have just a 6hc+3hc shouldnt it be address to 1 ? Or im missing something here

Addressing is arbitrary right? I certainly do not have tons of boards and channel 1 is free but I found it easiest to just flip them all to on in one motion instead of trying to be precise with flipping one switch.

Edit: Not totally arbitrary, but no right or wrong answer as long as its logical

kroybal

Very coarse statistics on my setup suggest about a 1/15 shot at lighting up upon startup, and 2 minutes light-up-and-sync time in the case of a startup failure.

Does this have to do with the crystal oscillators not powering up still or simply waiting for the signal from the boards to be in phase?

jrockland

@kroybal not a clue, it is why I was asking. I tough I was wrong doing it 1-2-3...

@dc42 Following a full update to 3.3beta seemed to be working at this point. It doesn't light up immediately but it flashes about two seconds later (w.r.t. the other LEDs) overall takes less than 10 seconds to sync with the MB. I cannot complain!

Cheers

Edit: I should have bit my tongue, I tried another time and the LED failed to turn on all together following power up. It has been about a minute and no light.

Thanks for the update. I'll continue working on this and provide another update tomorrow.

dc42

@kroybal, I've put an updated 3.3beta Duet3Firmware-EXP3HC.bin file at https://www.dropbox.com/sh/wme9k0z86sytg33/AAAT6wrHp2eeJHK-dYoW1Um4a?dl=0. Please install it and see whether the delay from power up to when the LED on the 3HC starts flashing is eliminated.

kroybal

@dc42 I have installed the updated EXP3HC and it seems like the problem is still persisting.

Here is my M122 command for both boards
