What does this reset code mean? What was it doing -- I've had a few random reboots -- usually after a print.

dc42

Which Duet, and what firmware version?

kazolar

Duet Ethernet with Duex5 - V2.05.1

kazolar

@dc42 another random reboot -- right at the start of the print -- during homing routine

With 2.05.1 i get randomly disconnected as well...i just get back to 2.04 and all are fine now(duet wifi)

@kazolar, I suspect the problem is too many interrupts arriving from the DueX, causing the main processor to spend too much time servicing them. So:

Do you have any endstops or other inputs connected to the DueX? If so, what sort of devices are connected? If they are endstop switches, are the wired NO or NC?
Are you able to upgrade to RRF 3.1.1? That release has additional diagnostics, in particular it reports the I2C transaction rate.

kazolar

@dc42 i have duex5 fully loaded with end stops -- I've mentioned it before, I NEVER use NO end stops. I plan on upgrading to v3 -- but due to ongoing need for PPE, I am still printing shields, so don't have time to do that -- I will move the boards into a new case to make wiring much easier to see. This generally happens very infrequently, normally it happens right at the start of a print. My start is heat up the bed to 75, heat 3 extruders to 140, home call bed probe routine then park and heat up to final temp -- the last part is where it tends to reboot - it has done all the probe triggering and is just waiting.

dc42

Just a thought: if you are parking the machine with one or more axes against the endstop switches while it is heating, try moving the head slightly away from the endstop so that it is no longer triggered.

kazolar

@dc42 ok, so, normal condition for the triplicate print is the 4th tool is inactive and is parked and obviously triggering an endstop, the heat up actually starts right after the probing completes and several optical end stops are triggered at that point. I have an option to run gcode that backs them all off the trigger point, I'll do that next time, but unlike the i2c emi issue, this one is really hard to hit, it happens ones every 5-10 days.
