[3.4beta6] Toolboard missing extrusion and M122 error

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?

@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.

@dc42 Would it be any help to record the CAN bus transmission with a scope, or run a firmware version with more verbose logging?

Phaedrux

I'm not sure it will help, but 3.4 final has just released, can you test with that?

https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.0

Pakue

@phaedrux Unfortunately, it still shows the same problems.

dc42

@Pakue, is this still a problem? If so:

@pakue said in [3.4beta6] Toolboard missing extrusion and M122 error:

@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.

If the bed heater is being driven directly from the Duet (not via a SSR or mosfet switch) then it's still possible that ground noise caused by the bed heater PWM is causing the problem, because the bed heater ground and main ground are commoned at the Duet. In which case, I suggest you provide the tool board power by daisy-chaining the tool board power cable from the main board power terminals, instead of directly from the PSU.

Pakue

@dc42 I'll try that, but I don't think that is the issue in that case, as the M122 error also happens after the print is done and the heater is off.
