Duet 3 + Tool board intermittent error

@evomotors said in Duet 3 + Tool board intermittent error:

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.

I can try to heat-up the chamber to 70, check processor temperature, try to level. I added if condition after each G30 in bed.g per your recommendation. Should save me from another accident.

It's common to get 1 write error and 1 timeout when the board starts up.

Hiccups are normally caused by the step rate being higher than the board can handle; however the 3.1.0 tool board firmware has an unusually low maximum step rate, which has been improved since then.

Please use the 3.2beta preview software at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0 on your Duet 3 main board for your testing. It includes the extra check that I mentioned earlier, to prevent probing if the tool board doesn't acknowledge that it owns the probe.

Is there newer tool board firmware?

dc42

There is newer tool board firmware, although it's not official yet.

Got new tool board yesterday but haven't installed it yet. Currently trying to restore/ground my tooling plate and reapply PEI.

Please use the new RRF 3.2beta1 on both main and tool board when you start testing again. If the tool board resets unexpectedly then M122 B# (where # is the tool board CAN address) will provide information about the reason.

Ready to test. how do I update the firmware to beta via DWC?
