jay_s_uk

@pakue looks like you have an issue with your CAN wiring between the 6HC and the toolboard

Pakue

@jay_s_uk It's printing fine except for the missed extrusions. Wouldn't signalling errors be caught by the CAN "lost" counter?

jay_s_uk

@pakue on the toolboard yes.
but you can't get any info from it, hence the

M122: Response timeout: CAN addr 20, req type 6024, RID=189

Pakue

@jay_s_uk I can try to shorten the CAN cable and add some shielding. Let's see if that helps.

dc42

@pakue the length of the CAN cable is not critical, neither does not normally need to be shielded.

The only time I have seen issues with CAN communication caused by other devices is when I had long wires between the PSU and a Duet 3 main board that was driving a powerful 24V bed heater, and there were separate wires from the PSU to the other CAN devices. In this case the differential ground noise caused by the bed heater turning on/off and the long wires to the PSU introduced a lot of ground noise.

The M122 B20 result is strange, because the board is responding to the first request for M122 data, but failing to respond to some of the subsequent requests. Does M122 B20 always run reliably when the machine is not printing?

Pakue

@dc42 I do indeed have a ~300W 24V heated bed, but the wires are >2mm^2, 30cm in length and split at the PSU between heated bed and the rest of the electronics. I can measure the GND offset/noise at the toolboard when everything is heating up to double check.

The M122 seems to be unreliable during printing, but works (at least sends some data) when the printer just started. About after a print; I'd have to check that.

With RFF 3.3 the M122 doesn't show errors.

dc42

@pakue please make the GCode file you are printing available. I will then test it on the bench, including running M122 while a print is running.

Pakue

@dc42 that one is running 0.9mm extrusion width on a 0.4 nozzle, but I can slice it with standard settings if preferred. The issue is reproducible on other settings too.

Standard_Box v19.gcode

Pakue

@dc42 DC offsets between toolboard GND and Duet3 GND input are

17mV default
33mV with bed heater on
430mV with hotend on

For noise measurements I'd have to pull out the scope.

After a print once everything is turned off (fans, heater, etc.) the M122 still throws errors, so I'm guessing noise is not the root cause?

T3P3Tony

@pakue i agree it looks less likely that noise is the issue. Can you try reinstalling the firmware (M997 B20) on the toolboard. ensure you have the 3.4b6 toolboards firmware binary in the /firmware directory on the SD card.

Pakue

@t3p3tony Updating via CAN it gets stuck on "Please wait while updates are being installed..." and the toolboard only shows up again after downgrading the MB6HC to 3.3.
Even resetting the toolboard (both buttons pressed while powering up) doesn't reset it to the original address (121).

V3.3 on the MB6HC returns the full M122 as far as I can tell

@pakue thanks that's an interesting result! now you have it working and returning the full result can you try the following:

try the firmware upgrade again
then try upgrading the mainboard to 3.4b6

Pakue

@t3p3tony Upgrading the toolboard to the beta6 works, but after upgrading the MB6HC the M122 issue persists:

@pakue thanks. I will need some input from @dc42 on this one!

Pakue

@dc42 Did you have success recreating the issue on your machine? On 3.4b7 the issue still persists.

dc42

@pakue I did not succeed in recreating this. Please test with 3.4.0rc2.

Pakue

@dc42 The issue still persists with 3.4rc2. I've also tried shortening the CAN cable without success.
