Intermittent communication disruption between 6HC and 3HC

[dc42]

I think the slow statup is another instance of this issue https://forum.duet3d.com/topic/21224/can-connectivity-duet-3-mb6hc-to-exp3hc. Please try the beta firmware at https://www.dropbox.com/sh/wme9k0z86sytg33/AAAT6wrHp2eeJHK-dYoW1Um4a?dl=0.

The assertion failure appears to have been caused by a stack overflow. I will examine the stack trace.

@dc42 Thank you. I'll try it out and will report here.

@dc42

Here are the results of what I found after trying the 3.3 beta.

Quick summary first, then a bit more data (and diag logs at the bottom).

1. IMPROVEMENT: 3.3 beta solves the 3HC not initializing the CAN sync process on power up (I assume that's why the LED would only start flashing after about 25-30 seconds on 3.2).

2. REGRESSION: 3.3 beta does NOT solve sync issues on power up between 3HC and 6HC until a power cycle is performed (in 3.2, emergency stop would be enough to get sync).

3. NO CHANGE FROM 3.2: DHT22 still does not work, but this time I observed a something weird. In general - on 3.3 and 3.2 DWC still shows 2000C and 2000% (is fine on 3.1.1).

4. NO CHANGE FROM 3.2: Bootloader ID still shows not available

5. NO CHANGE FROM 3.2: Last software reset is still set to AssertionFault (although I did not expect any changes here).

Here's more info:

I started with uploading the firmware to 3HC.

The CAN LED now starts flashing immediately on power up and flashes quite fast (faster than on 3.1.0).

I then updated the 6HC to 3.3.

The 3HC does NOT get connected to the 6HC on first power on. 6HC flashes slowly, 3HC flashes quickly. They didn't sync after 30 minutes of waiting. I then hit the Emergency Stop button - in 3.2 - this would solve the lack of communication, but on 3.3 it did not. The boards don't sync up and each flashes differently.
However, after a quick power cycle - the boards immediately sync up on boot.
I am attaching logs that show this below.

After that, everything works except for the DHT22 connected to the main board. That still shows 2000C and 2000% (nothing changed with connections - and these work perfectly fine on 3.1.1).

The very weird thing I observed with the DHT22 on 3.3beta was that I left the printer on for about 10 minutes without touching it. When I cam back to it, I noticed that for the shortest moment, DHT22 readings were available, but the moment i started switching between tabs - readings went back to 2000C/%.

I rolled back to 3.1.1 and immediately the readings came back.

I'm attaching two screenshots of what this looked like (first shows the jump to 2k, then down to normal values, then back up to 2k, where it stayed until I rolled back to 3.1.1 visible on the second screen, where data is updated normally).

Diag logs from cold power up, lack of sync on emergency stop, but immediate sync on power cycle.

Thanks for the update. Your M122 trace for the EXP3HC indicated a stack overflow, so I've increased the stack size and put a new 3.3beta Duet3Firmware-EXP3HC.bin at https://www.dropbox.com/sh/wme9k0z86sytg33/AAAT6wrHp2eeJHK-dYoW1Um4a?dl=0. Please try it.

[pkos]

Will do and report later Thanks for the help

[pkos]

Small update for now, I'll write more details later. I need to get a couple prints out fast, so for now I'll switch to 3.1.1.

On the newest beta - connection is quick, no reboots necessary, seems like the initial bit is solved.

However, with that beta - I am unable to complete any print as at some point, the 3HC (which for me runs the extruder, hotend, hotend cooling and filament monitor) probably stops communicating with the 6HC and I get skipped steps, underextrusion and in general - failed prints.

Switching back to 3.1.1 makes it all run.

As soon as I get the next things printed, I'll start investigating more, including diag logs from immediately after a print fails.

Thanks for the update. I am sorry we haven't managed to resolve this issue completely yet.

When you get a chance, I would appreciate it if you can do the following:

• Install the latest beta firmware from https://www.dropbox.com/sh/qr98k8fbkj5ue0k/AABPawUF99QVzDrheBQBDSxia?dl=0
• Run a print up to the point at which it starts failing (assuming it still fails)
• Pause the print
• Run M122 and M122 B# (where # is the expansion board address) and post the results
• Resume the print, and see whether doing the pause has fixed the issue, at least temporarily.

Thanks for your patience.

[pkos]

I'm almost done printing the last order, so I'll have more time to experiment tomorrow. I'll report afterwards.

Thanks for being awesome and helping out!

[pkos]

Quick update.

I'm 5 hours into the print, so far the print has not failed, no skipped steps or underextrusion, etc. The 3HC starts flashing quickly immediately, catches sync within 2-3 seconds.

There is one more test I need to do - if all goes well, I'll have it done tomorrow morning - that's to check how the 3HC behaves after a long power off (at least one hour). For now I've had the printer running pretty much 24/7 since Saturday.

I ran a quick M122 just in case you want to see what's going on right now (pasting below). The assertion failure is still there and DHT22 does not work.

I'm sorry to be the bearer of bad news, but it's much worse now. I don't know if it's related in any way to the firmware shuffling of late, but now, I can't seem to be able to get a single print off successfully that takes longer than 8 hours.

Almost immediately after my post last night, I noticed that the printer stopped moving and paused on it's own. There were no messages in the console. The printer was just stopped above the print.

I hit resume and the printer seemed to try to move the carriage, but was unable to. It was just stuck in place and jittering around. The display on PanelDue showed significant changes in location, but there was only jittery motion.

I aborted the print and started another, fresh gcode again in hopes that it's just a fluke.

Alas, it was not. A night print that was supposed to take 9 hours froze sometime around the 7th hour (I can't tell for sure).

This time I grabbed diag logs from before I hit resume and after. I'm pasting them below along with my current config.g file.

To be sure - after I hit emergency stop on the panel, everything was moving perfectly fine, so it wasn't something mechanical that would prevent the printer from moving. I did notice that the quality of the print is much worse on the z axis - something I never had an issue with before.

I am now getting very worried that something more serious broke and will have the printer down longer.

Do the logs tell you anything?

@pkos, thanks for your reports. I'm sorry that you have lost two large prints.

As the head movement was not correct, the problem appears to be occurring on the main board, not on the EXP3HC.

Can you share one of those GCode files, so that I can run it here?

I am about to prepare a 3.2.1 build of the EXP3HC firmware. This should allow you to revert to RRF 3.2 without experiencing the slow startup issue on the EXP3HC.

[pkos]

Here we go then.

This is the file that I tried printing since last night where it failed both times.

https://we.tl/t-6WJmPSXoAq

Great news on the 3.2.1

I know I am probably getting annoying by now, but I'm one of those persistent people. The assertion failure is still there and I see that the bootloader ID is not there. Is this as it should be? Or maybe 3.2.1 will solve the problem?

EDIT: One more note - both prints failed at a different point in the gcode. One much earlier than the second one.

The assertion failure report is the saved info from the crash when you were running older firmware. This is clear because the free memory and stack trace are exactly the same as before; whereas if the same crash happened again now, at the very least the free memory would be lower. What's happening is that "normal" software resets such as when you installed the new firmware did not clear out the data.

If you wish, you can replace the software reset data by sending M122 B2 P1004 to provoke a deliberate reset. The software reset data will then report a deliberate zero divide error.

The bootloader ID is not reported because older bootloaders do not report their ID. But please do not update the bootloader at this stage.

Thanks for providing the GCode file. I will run this on the bench to see if I can replicate the problem.

[pkos]

And now it's perfectly clear - thank you I am much more calm now.

For now, I'm back on 3.1.1 running prints - so far so good.
I'll wait for the 3.2.1 to see if that helps at all.

Then the last thing to solve for me will be the DHT22. 3.1.1 - works perfectly. Switch to 3.2 or 3.3 - nothing. Values jump to 2k.

This is on my list to investigate.

The candiate EXP3HC 3.2.1 firmware is now avaiable at https://www.dropbox.com/sh/1lwimb98k6hzz3z/AAApVr_P6roUjnya4riDbGAba?dl=0. This includes the fix to the slow startup issue (LED not starting to blink immediately after power up).

Have you run any long prints using RRF 3.2 yet?

[pkos]

Not yet. For now I quickly printed the rest of functional parts in small batches, but I will give the new firmware a try.

OK, in that case bear in mind that 3.2 might have the same issue that you saw with 3.3. You might want to try an air print first to save on filament.

[pkos]

Will do.

Quick question - do I need to redo PID for 3.2? I thought I saw that there is a new algorithm, but it's not necessary to redo PID.

I am seeing some very weird behavior on 3.2. Regardless of the temperature I set on the bed, it drops temps without the firmware screaming bloody murder and thermal runaway.

Attaching screenshot. Please note that the temp is 100C, while it's set at 105C.

Hotend temp dropping was my doing.

Just in case, log from the main board below.

@pkos I would say it's worth trying the new PID tuning. The old values should be usable though.
