@gloomyandy this is a great idea. I would love to try it, but it seems the exp1.lcd_rst pin isn't exposed looking through https://github.com/Duet3D/RepRapFirmware/blob/3.4-dev/src/Config/Pins_Duet3Mini.h
Is there an alternative name @dc42 ?
Edit: Actually, I took a look at the big dipper schematic and it's simply shorted to 3.3v to pull the signal high. It seems like triggering lcd_rst wouldn't be possible
