Wanhao Duplicator i3 Marlin
thingiverse
Wanhao Duplicator i3 Firmware This firmware is compatible with the original LCD and Melzi board. I had to create a custom thermistor table because the standard board uses 10k pull-up resistors instead of 4.7K, which I'm not entirely confident in. Additionally, I edited the config file for the Melzi board to get the lcd working properly. Manual bed leveling is also enabled in Marlin (use paper and adjust up/down until it gives some resistance). To update the firmware, you will need a bootloader. Please see: http://www.instructables.com/id/Using-an-Arduino-to-Flash-the-Melzi-Board-Wanhao-I/ I have uploaded a new version of marlin 1.1.9 as I no longer own my Wanhao printer, so if you try the new firmware, please let me know if it works correctly. The firmware also features babystepping (similar to Prusa Live Z Adj).
