Very nice. Just wondering what version firmware are you using? Could you post the source?

I'm using a Firmware derivative Marlin 1.3 made by Bq.
I have modified it to use this LCD and a heatbed.

I tried Marlin v1.4 by Bq and all I got was brightness on the screen. I will try v1.3 and possibly a new lcd. Thank you for the reply and imformation,

If you want i can send you my firmware for you to try

Thank you for your kind offer. I have modified my Hephestos by adding a heated bed, and automatic bed leveling. Soon I will be adding the bed extension also. When you added the Reprapdiscount full grahic smart controller did you do anything to the configuation.c file other than uncomment the line for Reprapdicount full graphic controller?

Yes, there is a lot to modify, you have to comment the "Witbox", but then you lose the "load, unload" menu. The knob is running backwards, and the movement of the knob is on 4 steps. there is a lot to change...

I got it working a couple of days ago from the Marlin original repo. As you said the official Marlin has not got the "load" / "unload" menu but I came up with a workaround that works great, actually I added them to the menu, there is only an extra step after you load or unload and it's practically the same as in the BQ modified Marlin. I also modified the knob to get it working as it was on the original display. If anyone wants a copy I'd be glad to post it.

Can you post the files?

That version has not been modified for a heated bed or auto leveling, but it should not represent a problem if you do make those modifications. As it is right now it will only work in spanish and english, because of some strings that are not in other languages, you are also welcome to add those strings in your language so it compiles ok. When you use the "Feed Filament" or "Unload Filament" options in the "prepare" menu, every time after you have used any of those, you have to go and select the option "Set 0 Filament" For the Extruder axis to go back to zero, I tried to add that command in each of the separate options, but the GCODE would not work :/ Anyway it works! The "Load Filament" option is not working as of right now, but the Feed Filament option will do the trick, they are the same. Hope it works for you.

Thank you, i have my own version working, the only thing is that you have to preheat fist.
