Repper's delight

If you want to add a lot more functionalities to your Weedo Tina2 3D printer you need to modify the firmware.
Unfortunately Weedo hasn't published the Tina2 Marlin firmware source files which is not respecting the Marlin GPLv3 license.
Therefore I had no other choice than trying to hack it.

It really wasn't an easy task, especially because I've never done that and did never look at Marlin or what a firmware is before.
So I guess anyone can do it. It's mainly a matter of finding the good informations, which is kind of a "detective game".
Yes... I spent more time over the internet than diving in the code.
All in all, it took me one complete day + complete night (24h of fulltime work) but I finally did it !

I now have all the advanced functionalities that the Marlin firmware offers and that's really cool !

EDITED

I just saw that Weedo finally released their source code a few hours after my hack and I'm glad they did ! Thanks Weedo.
I can now see that the motherboard version is 62AS while I did all my hacking expecting it was a 62B. But still mine works after guessing all the pins to configure.
Finally, did I work hard for nothing ?
I don't think so... I learned a lot at hacking the firmware !

But the problem is that it's kind of impossible to compil Weedo's firmware because it's full of errors.
I just spent 3 hours trying to fix them all with no success and decided to give up. I will continue developing my own that allready works very well and is based on last Marlin firmware (2.0.9.3) while their release is still based on Marlin 1.1.x
But I will keep an eye on Weedo's updates.
