Re: Davinci Jr Repetier Port

Is there any progress in porting the Repetier firmware to the DaVinci Jr.? Love to see that on my DaVinci Jr.

@ XYLenTech

hi LenTech,
in post number 6 you wrote that You are able to read from the chip. Could You please figure out wether this from the chip is encrypted or decrypted and is it the firmware or anything else?

Re: Davinci Jr Repetier Port

Just a thought, but I'd read somewhere amongst the various threads about putting the Jr. in Bootloader Mode. Not sure if this would have any similarities to a JTAG interface with trace and debugging facilities, but maybe? And, if so or something along the same lines, could possibly dump the unencrypted FW in flash? Just thinking out loud for better or worse.

Just like all Da Vinci models it is encrypted. When you read from the device all you get is a hex file. That files will have to be decompiled. In order to do that you have to know how it was compiled.

Yes, you can start bootloader mode on the Jr and flash it, but Repetier still doesn't have definitions for the pins on the Jr board. Someone needs to work that out still,  and I don't think the motivation for doing so is very high on this model.

I went a different route and got rid of the board altogether.

Efforts for a repetier conversion seem to have just died. It seems it is most likely easier to just replace the controller with a RAMPS setup and call it done. I would have liked to have seen someone just crack this POS open so those of us with wives and budgets would be able to thumb our noses at XYZ and their overpriced, limited option and color, limited availability proprietary filaments and just rip that incredibly stupid NFC reader out of the machine forever! Not to mention the horrid excuse for software XYZ vomits onto our computers along with their own advertising. It appears they spend much more time and energy developing their advertising than they do making effective software.

The only positive thing I can possibly say about XYZ is that they did spend some time on the enclosure of the Jr. Obviously much more than into anything else including packaging as mine arrived with the left side plastic having been banged during shipping and cracked at the top. Aesthetics, surely, but still.

As there seems to be no further development on a repetier port, I'll surely be looking into a RAMPS conversion while trying to maintain the integrity of the existing enclosure.

Re: Davinci Jr Repetier Port

No, it is much easier just to replace firmware... Hardware replacement requires major rewiring because connectors and cabling are not compatible...
I just bought my jr used for US$ 135 and planning just to do that, porting Marlin starting with pin assignment for the processor...
It looks that this is an advanced board since it has laser scanner features partially populated...
It is going to be fun anyway...

Re: Davinci Jr Repetier Port

Marlin support SAM4E8E cpu ?

Actually swapping the hardware would be much easier. As Luc also asked. I don't believe Marlin supports that Processor. Smoothie would be a closer match firmware wise. It is not as simple as remapping pins.

Great help thanks, I got this installed on my junior and now changing pin assignment and LCD support...
When I plug the junior usb it starts OK reporting Duet 3D printer control electronic (COM4) and the lights inside printer comes on... But LCD still has just two horizontal bars...
This is fun, I will update daily until full conversion is done...

clkin pin 3 sam 125
cw/ccw pin 44 sam 7
x motor
enable pin 2 sam 127
enable pin 3 sam 128
cw/ccw pin 44 sam 126
E1 motor
enable pin 2 sam 76
enable pin 3 sam 78
cw/ccw pin 44 sam 74

Be careful if power on after wipe the FW, the extruder is on and heating without any control, you better disconnect it
Allen was planning to work on tracing the extruder connector as I was not able to find the proper trace - I am terrible for this

Also be noted duet FW variant may need adjustment as it match the duet board not davinci jr
Also I guess you know duet do not support standard lcd neither keyboard, you need extra coding implementation for this, on duet this part is handled by standalone screen connected by serial

no mention about the thermistor table that I doubt to be standard on Jr if they use same mindset as others davinci

Re: Davinci Jr Repetier Port

Thank you, that is big help!
I have  https://duet3d.com/wiki/DuetWifi_Pinout_table  to compare with junior and davinci 1.0 ported to Repetier-Firmware-0.92, and your pin assignment data...
I am compiling RepRap Duet FW since it is based on Marlin and well documented...
I will post an update hopefully with success :-)

Re: Davinci Jr Repetier Port

the only common between Jr and others Davinci is the screen pad - a 16x4 winstar screen so initialisation is little bit different than others lcd -  it took some time to make it work perfectly - you can check the specs of the screen on my github (https://github.com/luc-github/Repetier-Firmware-0.92)

Yes, thank You...
I am  working on it now as it will be usefull for debuging of other parts...

Re: Davinci Jr Repetier Port

I was able to setup eclypse neon 2, GNU Tools ARM Embedded and GnuWin32 for compiling original RepRapFirmware-dev...
For downloading FW.bin I used recommended sam-ba_2.16... All that because original build recommendation does not work on win 10...
There are two pads for erase and reset switches on jr motherboard and I have populated them with appropriate size push switches:

I am doing lot of FW flashes and each require manual erase and reset...
Also I found the stepper ic doc:   https://toshiba.semicon-storage.com/inf … TB62269FTG
All now ready for PIN match work and I should have some action this weekend...

Re: Davinci Jr Repetier Port

Wow, nice work. It would be nice if its working with the Arduino IDE. I've bought a Ramps 1.4 Kit today for 35€, but it would be nicer if I could use the Davinci Jr Board.

Re: Davinci Jr Repetier Port

Well we really want  SAM4 ( faster / 32bit/floating point ) between 10x-100x performance  ...  but I will agreen samp is a good poorman solution ,

Re: Davinci Jr Repetier Port

Gentlemen,
With the Da Vinci Jr. 1.0 OPEN BOX sitting at $153.99 on Newegg, I am especially intrigued by your work and would love to use it if it comes to fruition. If there is any way I can be of assistance I would like to throw my hat in the ring.
Happy Hacking!

Re: Davinci Jr Repetier Port

Lemme know what I can do to help. I have a brand new Jr sitting in the corner right now just itching for use, but not without a filament or firmware solution I can try to help map pins (have an older multimeter i can use).

Re: Davinci Jr Repetier Port

I have the RepRap firmware running using remote access trough USB port. It is printing and I've enabled the debug messages an can see all printing parameters. Still tracing pins and found temperature controller is an advanced circuit outside the sam processor so I have to draw full schematic and identify components involved. As mentioned before there is no LCD support so after I get all pins running I will switch to Repetier since it already has the LCD support which will also require to write new platform interface using sam4e. In any case I will not give up porting open firmware on davinci junior 1.0...

Re: Davinci Jr Repetier Port

can you share the additional pins you found vs the ones I provided ?

Re: Davinci Jr Repetier Port

Where are you guys with this right now, finally decided I was done with XYZ's OEM solution after battling with customer service over bad filament continuously clogging my extruder. I am a computer engineer and would love to help and get a comprehensive guide going as a big "F you" to XYZ
