klipper config for modified wanhao d9

printer.cfg

# This file contains pin mappings for the Wanhao Duplicator 9 MK1,
# also sold as the Monoprice Maker Pro MK1. To use this config,
# the firmware should be compiled for the AVR atmega2560.

# See the example.cfg file for a description of available parameters.

Would you happen to know what the pin numbers are on the small EXP plug, and also on the wider side plug? By knowing these mappings we'll be able to generalize and permit connecting any display with a suitable adaptor to these ports. Best guess: https://github.com/MarlinFirmware/Marlin/pull/28073/files#diff-b84605ec433708e7146686b8586748e21326c4d48172f870b451c9b7a4408177R117-R131

I've since disassembled this printer and don't have a way to verify the pin mappings, unfortunately!
