da Vinci Jr. 1.0

[Danal]

Uhhh.... the DaVinci Jr. 1.0 seems to have a main board that is a combination of an Arduino Due and a RAMPS style shield.

Specifically, it has a SAM3X8E processor. I'm sure you could get Duet/RepRap to compile to that target in Atmel Studio, but, that chip has 512K flash and 64K RAM. The RAM in particular is concerning. Duet2 hardware has 128K ram. Cutting RAM in half on an RTOS is not a good thing.

Perhaps you could take enough things out of the code to make that work. Maybe.

And... that board has "POLOLU" style drivers. Meaning probably A4988 or DRV8825 from the factory. You COULD replace those with TMC2100s, maybe.

Having said all of that, you know there is a version of Repetier that can be configured to "just run" on that board, with no other changes? Nowhere near as nice as Duet/RepRap... still, it is known to work.

Were I in your shoes, I'd either put Repetier on the existing board, or remove that board completely and install an actual Duet 2.

Repetier is available for the Da Vinci but not the Jr. Not ones got any custom firmware to run.
It also has a variant of Toshiba drivers.

Ahhh... much more clear. Atmel SAM4E8E. Which means it actually does have 128K Ram.

Might compile and load!

Does anyone knows what type sockets and plugs used in JR

Regarding the schematic and getting RRF to work on this machine, you may find this useful https://github.com/dc42/RepRapFirmware/issues/190

Thanks again for info.I all already read this,sound Like JR hitting wall.

Just to summarise the idea:

*Reuse the Board
*Cannibalise the board-to rid off unnecessarily chips .
*Use fly wires “soldering “ to make connections
*Make it us much as Duet WiFi as possible
*Add WiFi module

bolded textitalicised textHelp required it just basic pin swap in source files (What files to edit for pins swap?)to match stepper drivers, end stops, thermistor and heater signals (pins).Very basic requirement to kick jr printer live. Jr can live without lcd .sd card slot should Mach pins anyway?!

SOS LoL

What files to edit for pin swap???
!!!Marlin was easy edit pins.h!!! ,and that’s it .
Is this the same with RRF???or Duet WiFi

“Let of the chest:Nothing personal”
“Rant
Lack of 4x20 or4x16 support??? And keypad?.
No videos on websites from duet creators with simple basic Tutorials -who is dreaming about duet3?? Duet2 is fancy enough!!!.
Why not spread the word about duet2 WiFi (Video support) and lower original board price to increase community.
“Board overpriced”!!!
Is where to many flavours in compile folder?!?and makes everything confusing.”

Once again nothing personal...

Thanks

no, because RRF is specific for the duet.

there is a lpc port of RRF
https://github.com/sdavi/RepRapFirmware/tree/v2-dev-lpc/EdgeRelease/ExampleBoardConfig
which has support for the popular skr v1.3.

there are a lot of tutorials on how to set up the duet on youtube
as well as a good guide like this https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+1:+Wiring/37

Why not spread the word about duet2 WiFi

i dont think there are many people that have invested time into 3d printing that have not heard about the duet.

the duet hast the paneldue
the maestro supports the standard 12864 lcd. why would you want 4x20 support?

[PrintMake]

@Veti why would you want 4x20 support? Because junior printer has

[Veti]

well you have your work cut out for you.
i dont think you will find a lot of people that are interested in doing this, as the price of the davinci board is more than the duet.

@Veti oh did not see this,yes it is ripoff price..

The pin definitions are in two places:

• File CoreNG/variants/DuetNG/variant.cpp describes the capabilities of each pin. You would only need to change this file if you want to use a pin for a special function (e.g. a serial interface, or SPI interface) and the Duet doesn't use that pin for that function.
• The main pin definition is in file RepRapFirmware/src/DuetNG/Pins_DuetNG.h.

@dc42 And “NG” stads for?...

"Next Generation", the code name we used for the Duet WiFi before we announced it.

Thank you

@ViralTinker

Forgot to ask ,what for is chip next to WiFi module connected together?is it for reset?

It's to detect the leading edge of the chip select signal from the WiFi module and cancel the data request. It could probably be eliminated by changing the firmware on the WiFi module, however when I wrote the firmware for that module, the documentation of the ESP8266 was so poor that it wasn't clear whether the chip supported edge-triggered interrupts or not.

Thanks a lot
