3.3B3 certain lines cause firmware reset

[deckingman]

As my name was mentioned, the fault I'm experiencing is consistent in that reverting back to RRF3.2 fixes in and "upgrading to 3.3. causes it. I've repeated this a few times. There appears to be a reset of the main board (but not the expansion boards) which is bought about by running a macro which uses M116 to wait for heaters to attain their set temperatures. In my case, no conditional gcode is used in this particular macro and the machine is in stand alone mode (no SBC) running a 6HC main board and 3 expansion boards. So maybe a different fault to the OP.

[DaveA]

@gloomyandy Nope, just a single Duet Maestro with no other expansion other than a 12864 display connected.

[gloomyandy]

@davea I think @Alex-cr said that he was using an SBC, so it could be why you have not been able to reproduce the problem (the handling of conditional gcode is different when using the SBC).

@alex-cr please run M122 after it resets and post the response here.

M122 after the reset.

I am also running into a problem with variables on the SBC controlled machine. I am not super surprised as it just got implemented. Merely documenting the issue. Everything below runs fin on a D2wifi.

The following line in my daemon.g also cause a firmware reset:

set global.printcomplete = state.upTime - global.printstoptime 

The two global variables are defined in config.g. They show up in the object model correctly. I just cannot do math with them. I can set them without issue as follows:

set global.printcomplete = state.upTime

To be clear i am still using the 3.3b3+1 firmware for this as well.

[dc42]

@alex-cr Please post your config.g file.

@alex-cr thanks. I've updated the firmware binary at https://www.dropbox.com/sh/6fdfjn7fpjnk3vv/AADWZIXsKn5B_GsTauCx8Nsna?dl=0. Please try that one. Whether your daemon.g file succeeds or crashes, please post a new M122 report after running it.

[Alex.cr]

@dc42

Good news, the latest +1 appears to have fixed the firmware crashes.
Unfortunately the line in deamon.g that was causing the crash is now throwing the following alarm.

; daemon.g

set global.holdtime = state.upTime
set global.printcomplete = state.upTime - global.printstoptime 

The global variable "printstoptime" is fully defined according to the object model.

And as requested here is the M122.

@alex-cr thanks. As you are using SBC I'll ask @chrishamm to look at why the global variable isn't found.

[Alex.cr]

@dc42

Not a problem. Just doing my best to beta test!

[chrishamm]

@alex-cr This problem had to do with the space after the variable name. To work-around this problem you can remove spaces before the '=' from your daemon.g.

I've got a fix ready for this, thanks for your report.

[tristanryerparke]

Hey @dc42 I installed the firmware you linked to as I was having the same issue as the OP, I'm running MB6HC with SBC. It solved some issues but others came up. I thought that possibly these new issues were related to my TOOL1LC and 2x EXP3HC being not on the "dropbox" firmware too, so I uploaded and installed those versions with M997. The installations took an abnormally long time to complete.
After installing I am unable to communicate with any of the expansion boards and they all flash with this pattern:
3s Pause, three flashes, 1s pause, very fast single flash, 3s pause, four flashes, repeated.
I tried to downgrade the firmwares back to 3.3beta1 from the github, but am unable to communicate with the boards. "Response Timeout" from M997. I tried the reset procedures but the issue persisted. M112 B{tried for all three boards} gave the same Response Timeout error.
All boards appear in the object model browser but list "null" for all values except CAN address.
I can document the issue further when I am with the machine tomorrow, and or create a new thread if you think that would be better.
Cheers,
T

@tristanryerparke said in 3.3B3 certain lines cause firmware reset:

After installing I am unable to communicate with any of the expansion boards and they all flash with this pattern:
3s Pause, three flashes, 1s pause, very fast single flash, 3s pause, four flashes, repeated.

That indicates that the boards are trying to download firmware from the main board, but the main board doesn't have it in the right place. Most likely the firmware files are in the /sys folder on the SD card but not in the /firmware folder which is where the main board will look for them when running 3.3beta3.

Check that you are running Duet Web Control 3.3beta, then upload the tool board and expansion board firmware files again.

[tristanryerparke]

@dc42 Files were in /firmware and /sys which was why I was really worried originally. Seemed to be a problem with boards retrieving firmware from the Pi4 SD card. I solved the issue by going into standalone mode and restarting the machine. Then the boards were able to request firmware and sync.
All set now,
Thanks

[pkos]

@dc42 I seem to be having a similar issue.

I downloaded the 3HC and 6HC files from dropbox, uploaded it to the board.

I'm trying to get the accelerometer to work with the printer, so what I did was this:

1. Home
2. Level gantry (Voron 2.4)
3. Send m955 to set up the accelerometer (the response seems to ignore I10 I am sending and keeps reporting orientation 20).
4. Set movement to relative with G91
5. Trigger the command from the docs with:

G1 X-50 G4 S2 M956 P0.0 S5000 A0 G4 P10 G1 X50 F20000

6. Printer moves by -50, then resets. This happens every time now. It doesn't matter if I have the accelerometer hooked up via SPI or i2c. Always happens.

M122 from after the board boots up is as follows:

We hope to release 3.3RC1 later today. It includes fixes for these stack overflow issues.
