https://forum.duet3d.com/topic/14774/how-to-add-a-graphical-display-to-your-printer/18
with external SD card access, awesome! Thank you!
I need to update the firmware first , ran M115 to see:
FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 2.04 ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2019-11-01b1
It's not finished but here is the link to the Guide
https://duet3d.dozuki.com/Guide/Duet+2+Maestro+in++FlashForge+Creator+Pro+(2016)+and+a+smart+12864+LCD/57
so far I was not able to get smart graphic 12864 LCD to work and my heat bed temperature is off.
Please comment here on corrections for the guide as well.
Thank you.
ok, I was able to confirm with the multimeter, with power off and using continuity to find where GND and 3.3v is and can figure it out from there.
and just noticed, looking at the solder joint, the one is square is indicating pin 1.
