i have a duet 0.8.5 and a spare node mcu …so i thought ill put the two together and get some wifi going i know this can be done because since the duet wifi runs on esp8266mod .

now that post is from 2015

the code would have evolved
so im planning to flash the node with DuetWebControl firmware then run connections into the board

im pretty sure it wont work

cuz

Important! Each version of DuetWebControl usually only works correctly with the version of RepRapFirmware that was current at the time of its release. Therefore, if you need to update both RepRapFirmware and DuetWebControl, update RepRapFirmware first.

so what are my options
anyone know of a firmware compatible with 0.8.5 ..?

got a new sd card slot from t3p3 fixed it and it runs perfect, i checked out the old slot ….and it was bad contacts inside the sd slot.
anyhow
thanks to David & Roland for the assist

even better …!

thanks

so i checked the connections and they seem good on the outside. Test came out negative so its probably contact problem is inside the sd slot itself i did them again just to make sure, and emailed t3p3 about replacements.

ok the good news,
i think i can still run without the glitch
maybe by setting the entire config in a macro and then calling it, that should work for single runs
till my replacements get here, thoughts..?

or
for smaller macro
what can i add to the macro, what else has to set other than motor currents

and is it possible some smd surrounding the sd is the cause, maybe the (R73) marked 473, it seems to be connected to the CD pin

ok thanks david
ill look into it and get back to you

this is probably too costly
but guys spring loaded terminals are sweet….
and no one out there has them integrated, its always tight as hell

just like old times..! some things just work..!

i re-soldered the pins on to the pcb it still has the same effect its probably internal in the sd slot

it reads every time on M21
that's whats bugging me how come it did not read before ;(

or
could it be that my config is too big and it times out before reading it or something…?

That's a good idea although pushing the wrong button hasn't happened to me yet, but its probably happening out there.
Anyhow i have decided to try and build a version where the duet is isolated from human intervention. This is really because
the duet seems to be very tolerant and fairly stable on its own. And constant tinkering ( stress test ) is kinda where things go wrong, at-least for me, i have 3 duet 0.8.5's and they all exhibit the same bizarreness of hardware bugging out (down-time) and i have been wanting to fork the firmware and add some hardware, I even had one of those big smd capacitors falling out (improper soldering), the fix could be just a matter of extending some ports and not tinkering with it directly, which should be fairly easy. It seems like an overkill but i can move on to doing something in the firmware and work out better printing or something.

(Kinda like usb hdd's where constant plug in's and pull out's eventually ruin the internal soldering compared to a direct sata on laptop internal hdd)

My main issue is the software reset which has to be processed by the sam3x8e
( i didn't read the firmware yet so i could be very wrong here)

but once initiated, there's a delay
so if I'm crashing on to something while homing or if a sensor fails me, i have to get to the power button
the hard reset seems faster, neater and always does the trick. So i got a fancy metal button for it. For now ill just solder some headers on the board reset and pull it from there, Hopefully all this will amount to an insanely stable duet (kinda like a pc).

My sd is formatted using SD formatter to FAT32, cluster size default

i have been using this duet for 6 months now and one fine day it stops working i had a problem with the Ethernet rj42 socket so i was using Ponterface for a while

now i don't think its a hardware issue because M21 loads the sd and it reads everything but it just won't load on boot plus once it boots there's nothing happening to the stepper motors when I'm trying to control it from Ponterface, probably because config.g didn't load on boot. i dont know whats going on is it my config….?

i even tried a different sd card

a 4gb and a 16gb, both giving me the exact same result

i think both the reset and erase need jumpers, once wired the duet is filled with wires going in from all sides. and if you were building some kind of casing, one side would require to be very close to the panel i got some extenders to see if i can move the board towards the center of the casing and mostly avoid touching the board every time i need to get something done ( I'm thinking some kind of vertical or horizontal pc casing like stuff so it holds the psu and everything ) plus the usb is too close to the sd slot

i have attached some images of the thinnest usb and sd extenders i could find … the problem now is that its too close and i don't want to put them in any kind of stress, ill probably remove the usb housing and use a heat-shrink and see how that goes, and update once its done
