Duet 3 + Tool board intermittent error

MCU temperature: min 75.9C, current 75.9C, max 76.8C

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?

@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.

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

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.

@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.

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.

@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?

T3P3Tony

@evomotors

I am not suspecting the capacitors - just pointing out that the temperature should be ok as far as CAN bu stability. I was suggesting swapping the toolboard to see if either we could reproduce a problem with that specific toolboard - or if you could reproduce the problem with a new toolboard.

Yes. I assume you are using G32 in your slicer start GCode to perform levelling. In your bed.g file, after each G30 line add the following lines:

if result != 0
  abort "Print cancelled due to probing error"

I agree replace the board and or to perform any tests you want me to do.

Thanks, we'll get you a new tool board ASAP. Which reseller did you buy it from?

Filastruder

Thanks, I've asked Tim at Filastruder to send you another one.

I've added a check in the for coming 3.2beta version of RepRapFirmware that the tool board acknowledges the Z probe configuration before it start a probing move. However, I still need to find out why the tool board either lost communication or reset.

I wonder how they know where to send? Are they found me by email?

T3P3Tony

@evomotors Not sure, Tim may be in contact if you used a different email

Yes, looked up your order history by forum email. Replacement on the way tomorrow.

Already got FedEx notification about shipment.
What and how do you want me to test?

Can you think of a way to test whether the issue occurs with the new board, without risking damage to your machine if it does?

What I would like to determine is:

Whether the new board resolves the issue.
If it doesn't, what is causing the board to reset. I will probably have to send you new tool board firmware in order to diagnose this.

The 3.2beta1 firmware that we expect to release very soon has an additional check that prevents probing from starting unless the main board has confirmation of the proibe configuration from the tool board. This should protect against the worst consequences of the problem if it occurs again; but obviously it's better not to rely on that.
