Duet Maestro 2 stops mid print
-
Sorry for my silly question.. I cant find R84. I looked at the whole pcb and could not find any problems. Even did a good old shock test while it was at operating temp. Does not reset. Almost certain it is not the button or a loose component.
I dont have any fancy tools to remove the.button. Only solder sucker and iron. But this will be last resort only after confirmation of warranty replacement as advised.
I will send you a pm with and alternative solution.

@massynrt R84 is in the top right of your DSLR picture of the processor.
I think it’s probably a faulty component that builds capacitance, until something triggers it causing the board to reset. Could also be heat related, as it doesn’t happen when board is idle, only when running. Possibly just a faulty processor with the above issues. Really difficult to say!

Quick question.. the connectors for the motors are upside down vs the meastro. Thus, i have to redo them.. although the red blue green black is still the same.. .
What is the reason? Do i have to redo, or will it still work?
-
Might be something ooznest did with their config. I turning the white clips around.

it might run in reverse if you swap 1<->4 and 2<->3 but that can be fixed by reversing the config.
as to reason, unclear; are you refering to duet 3 vs duet 2 maestro? in any case to make routing the board easier is the likely answer.

@massynrt all Duets connect the motor phases the same way; one phase/coil to pins 1 and 2 of the motor driver pins, and the other phase/coil to pins 3 and 4. The labels on the wiring diagrams and on the PCBs have varied somewhat, for a number of reasons, but this order is the one that is implied, and is common to all Duets. It shouldn’t matter is you flip the wires per coil, as it will just change the motor direction, which you can change with M569 S[0/1].
So you shouldn’t need to change the motor wiring when changing from Maestro to Duet Ethernet, but you may need to change the direction in config.g.

Thanks for all your help @droftarts. I got the Duet 2 up and running.. Busy with first test print..
2 Observations:
- The prints are definitely slower. With the same config file, Except for the BL Touch config. The rest seems to stay the same from Maestro to Duet 2 .
- The motors are quiter. Alot.. Printer just feels better..
Any idea why??
-
@massynrt number 2 is because it’s different stepper drivers, and quieter because of different StealthChop settings. Not sure why it would be slower, though!

Spidy sense senses board has been replaced?
Does that mean its too late to suggest trying a stronger pull up between a reset pin and 3.3v?

Yes we worked out something to get going again.. Must say - I'm impressed with the support.. I know I started off a bit frustrated, but at the end i must admit.. I was wrong.. You guys are amazing.. @dc42 @droftarts Thank you for everything.
I got a test print finished with the new board.. Now to get the printer "perfect".

they're usually quite amenable indeed!
