ok timr,

You have to have the variant file replaced or you will likely destroy your main board. variant is not a sketch is is a board definition.
I think you will be best off using command prompt and flashing the pre compiled hex file.

https://github.com/bgm370/dav10

download zip and extract to a folder, Variant will be in that folder. also will be repetier-0.91-alpha-davinci10.bin

the other form already has a couple posts on how to do the bossa flashing

yes thank you w34, that worked and downloaded the firmware. It didn't unbrick my printer though, only heated up my bed and extruder. (maybe a pinout problem) the variant file is confusing because it only uploads test off the zip file on the sketch. Do we still need the sd card?
I checked the device manager and it can't find the necessary software. COM15 disappeared until I erase the chip again. In the manager above ports shows: other devices with a (?)/arduino due is cautioned(!). I'm pretty sure I downloaded all the right drivers from atmel

When I uploaded the github/repetier on the arduino sketch an error message: 'Timetick_Configure' was not declared in this scope. black bars appeared on lcd and now stuck at this point.

My Bossa flash programmer won't connect either.
I'll keep updated if I ever figure this out

Make sure you have the Arduino Due (native usb) selected in arduino. That should fix the problem. HTH

You did. I've posted this in a few places hoping for help. I installed the Bossa flash programmer, but while it recognizes my printer is on a port it tells me "Could not to device on COMX". I tried changing COM ports, but same outcome.

Thanks for your help, by the way.

I also posted in Voltivo with pics of my board.

I think I already replied to your comment on my video, but yeah it will be an easy fix using the bossac flashing tool through command line.

I think I softbricked the printer while trying to use Repetier. I get black bars when I turn it on. When I try doing anything through Arduino, I get:

" Sketch uses 10,380 bytes (1%) of program storage space. Maximum is 524,288 bytes.

Erase flash
Flash page is locked"

I must have an upgraded board because there are no jumpers or the 3 buttons I see on other boards.

My computer still recognizes the printer as "Bossa Program Port (COM8)" in my Device Manager.

Any help is appreciated!. Thanks
