So i bought the geeetech a10 printer a while ago, this is my second printer.
I was flashing the firmware so i could use the bltouch sensor and now my printer wont work, the lcd is just two rows of black squares in cura it detects the printer but i can only heat up the build plate and nothing else works ive tried to find the default firmware to reflash back to the way it was but arduino keeps giving errors on most files i find.
i followed instruction perfectly i used the right config.h file and set the motherboard in the file but it still will not work please help me.
