I have an original, very old Wanhao Duplicator i3. From the first pre-order old. I have been working on updating the software, by installing a newer version of Marlin (thanks, Nitrogen777 ((https://www.thingiverse.com/thing:2450111))). In the process, I toasted my display, via electric shock, and the only drop in replacement was $45 from some specialty website. No thanks, The RepRapDiscount Full Graphics Smart Controller is surprisingly similar, and runs for about $10.
After poking around, trying some other guides, I eventually just tested the pins, and found someplace on the back of the original board that they went, found the similar place on the new board, and wrote down what pin that was. Eventually, I mapped all 10 wanhao pins to pins on the 20 EXP1/2 connectors.
Attached is a PDF with the corresponding pins. Here is a description of the titles:
- Pin Name: The name in the RepRap schematic that this pin is for
- Wanhao Name: The name printed on the (not exactly a) melzi
