Duet 3 + Tool board intermittent error

[evomotors]

I have BL-Touch connected to tool board (board address 121) as described here. Everything works as expected, but once in a while when leveling, the probe doesn't deploy and nozzle crashing into my very expensive build surface living large dings. Everything start working as expected again only after power of and back on.

This is the error getting displayed after if fails to deploy the probe.

Is there a known defect in the firmware? Or Am I doing something something wrong

[dc42]

That message should only occur if the tool board is rebooted (e.g. because of sending M997 B# to upgrade its firmware) and the main board is not rebooted. If it is being reported at other times, the tool board firmware may have crashed and reset. Do you notice the red LED getting briefly out of sync with the main board?

[evomotors]

No, not really. It doesn't happen on the first probe point often, it could be second or third.

M997 B#

Also I have never sent M997 B121

Also it would be hard for me to see if lights are out of sync. I don't have hanging boards and wires.

can you confirm the firmware version running on the mainboard and toolboard:

Mainboard:

M115

Toolboard

Sure.

Thanks so they are up to date (just wanted to check since you had not updated them.

Can you send M122 immediately after you get this error

I'm immediately pressing [Emergency Stop] button on the DWC or pulling the plug to avoid further damage to print-head and bed surface.

Will M122 able to diagnose after emergency stop?

Am I overheating? what's why board resets?

The tool board is inside the heated enclosure correct?

I'm not sure how accurate the reported temp is, as there may be a bit of a margin of error. When first turned on a room temp, what does the temp read as?

Also I'm not sure what the rated temp is for the tool board, that temp may be too high, or it may be alright.

Will have to wait for @dc42 or @T3P3Tony to weigh in.

Tool board is inside passively heated enclosure (mains power heated bed and nozzle)

I did tried to cool down to 50-ish and it started working as normal again. Prior to that it was constantly failing. If heating is the issue, what's the point of the tool boards? Printing PLA in none enclosed printer?

[evomotors]

@dc42 and @T3P3Tony
It happen again for no reason. This time my $100 545x545x8 mm MIC6 toolplate has deep scratch, $95 PIE sheet completely destroyed and $30 genuine E3D-online titanium heat-brake broken. It already cost my several times more than duet tool-board and tool distribution itself. I'm still investigating if my BMG extruder survived.

I'm not getting any support for this issue and will strongly suggest not to buy the duet tool boards on my 2500+ members forum.

Please let me know how to return this buggy piece of hardware and get my money back.

[evomotors]

Update. E3d Volcano nozzle, BLTouch pin, and BMG extruder body also destroyed.

[Veti]

i am not a big fan of the bltouch. especially for the reason, that if the probe does not deploy it does not recognize it.

i prefer this simple design. https://www.thingiverse.com/thing:3303618 works just like a bltouch, but has some advantages.
unless deployed its triggered. meaning if it does not deploy probing will stop.
its optical/mechanical, not prone to interference like the bltouch
its cheap and has a very good repeatability.

[Phaedrux]

@evomotors Sorry to hear you've had such misfortune. Did it still produce the original error message?

This is wrong, there is a reason you just haven't found what that reason is yet

From looking at this thread I would say that you have 100 % been receiving support.

Please let me know how to return this buggy piece of hardware and get my money back.

You appear to be blaming the hardware without any concrete proof of it being at fault.

Whining like a little girl, stamping your feet after spitting your dummy out, screaming you don't recommend something just because you don't know how to carry out in-depth and logical diagnostics isn't really doing to endear you to anyone

Might I suggest that you take up another form of additive manufacturing, much simpler it only uses three components.

Its called knitting, you only need two needles and a ball of yarn.

[T3P3Tony]

@evomotors while the Toolboard is designed to be ok up to 85C, and that limit it the electrolytic capacitors and not the processor it might be the temp that's causing the issue. If you would be ok for us to exchange the Toolboard and you can run a series of tests (without actually probing the bed to avoid further damage) then we can see if the issue is reproducible.

I have 3 ball-screws and 3 independent motors and probe 3 points and center before each print. So when it happened last time, the DWC reported that probe is already triggered and aborted further probing, but it started the print.

Is there any configuration I can use not to start the print on leveling error?

Are you suspecting that one or more capacitors on my tool-board may not handling enclosure temperature? Or what is the reason to exchange the board?
