It was disconnected pin, I got hung up with short to ground error and was focusing on trying to find a short. Looks like on the side closest to the fuses one or more pins weren't connected, I did skimp a bit on the heat on that edge due to proximity of other components so ran a dry soldering iron over each pin and back to life now with all drivers working again. Many thanks.

I previously destroyed Z stepper driver on my Duet2 due to own stupidity (mixed phases, let the smoke out and reports over temperature / short to ground).

This board has since been replaced so thought I would try repairing myself. So I cracked out the reflow station and after a short while old driver was removed and new driver installed. Visually apart from a bit of a scorch to plastic for plugs everything looks good.

However I still get over temperature / short to ground error coming up from driver 2 but now on top of this none of the other drivers work all reporting phase A/B may be disconnected.

Is it totally dead? As mentioned visually I cannot see any issues even under magnifying glass all pins look lined up perfectly and no shorts to neighbouring pin (except intended pairs).

As mentioned not crucial as I have replaced but would be nice to have a spare for another project.

@dc42 received replacement board from E3D today and working as expected in standalone, will get round to putting SBC back in this week but happy there shouldn't be any further issues.

Thank's again to yourself and @chrishamm for the help

@dc42 MCU was over reading by ~2C so adjusted to compensate and showing ~35C now.

Installed new firmware and...

30/11/2020, 13:26:02	Finished printing file 0:/gcodes/[PLA] CFFFP_Top - ReRender - zero temps.gcode, print time was 1h 41m

So looked promising so without changing anything I reran print to make sure it was not a fluke and sure enough it was ...

@dc42 Thank you, will get in touch with E3D. Many thanks for your help.

@dc42 thanks for your time looking into this. Purchase was from E3D but I have just gone over the 6 months now (purchased 13th May), will you be able to authorise warranty replacement as reported prior?

@dc42 Failed again on beta4 (M122 at bottom) they are posted already but will group together here.

@dc42 any update on this?

@dc42 Thank you.

Config attached, not been changed from assertation failure (or from 3.1.1). No filament monitors.

config.g

Simulation loop ran for 4 1/2 hours (~380 loops) with no issues.

Ripped 24V PSU out of another printer today and unplugged heaters and fans so just steppers and sensors plugged in and done another test print, again this did not complete.

This time M122 back to Memory Protection Fault

@dc42 Stopped overthinking it and just added the M37/M23/M24 to the end of gcode which is looping properly now.

Has done ~130 loops with no issues in simulation.

@dc42 I've ran the file as a normal simulation which completes fine.

Trying to do a macro to loop it but my gcode knowledge is terrible and keep freezing the board can you point me in right direction?

Was thinking this (I know never ending loops are bad in themselves but was just going to let it run until I reset it) but looks like it is just buffering all the M24s in one go how would I go about waiting for it to finish one before starting the next?

M37 S1
M23 "[PLA] CFFFP_Top - ReRender - zero temps.gcode"
while true
	M24

@dc42 Many thanks.

Is it worth trying with DuetPi Lite? Was going to try earlier but work got in the way

@chrishamm No luck again on standalone with 3.2.0-beta3.2, this time "AssertionFailed"

I will have another try later with duetpi lite.

@chrishamm Thanks for the update.

Would using the non-gui version of duetpi and forgoing connected screen work around this issue for the short term keeping SBC control?

Have updated standalone to 3.2.0-b3.2 and running test again now.

I've put Duet3 into standalone now, retried print using 3.1.1 and print failed again. M122 shows Memory protection fault at time of failure.

@Phaedrux No

Added and needless to say it works now. Can I suggest the networking one being added to getting started. I presumed network would be always on.

Also the paneldue one to the paneldue bit on getting started as well, checked that to know to change wiring and what IO to use but was previously used on Duet2 with RRF2 so worked out of the box without any config.

@bearer YAT seems to stay connected to the port (which remains the same excluding switching to / from bossa). I have also tried putty which more annoyingly does disconnect but even with finger hovering over connect button for when I hit reset gives me nothing.

Speed is set as default at 9600 only change to YAT was changing end of line to <LF> as per Duet2 guide (https://duet3d.dozuki.com/Guide/1.)+Getting+Connected+to+your+Duet/7?lang) couldn't see any mention of speed on that (or I really am going blind!) but screenshot shows 9600.

(edit full settings) data bits: 8, parity: none, stop bits: 1, flow control: none

@bearer reset and totally powered off and back on. Board shows up as "USB Serial Device" not bossa.

Swear I am going blind firmware flashed and verified now...

Still does not see to be starting up though, powering on I get a flashing diag led, nothing on ethernet port / switch and paneldue still sits on connecting.

Should Duet3 output anything to serial port on boot like Duet2? Opening serial terminal and resetting board I get absolutely nothing through.
