Replacing the 12864 LCD

If for some reason you need to replace your 12864 LCD on your Crane you can use the following LCD to replace it. ... UTF8&psc=1

The EXP1 and EXP2 connectors on the board match but the pins are backwards so you'll need to plug your cable in upside down to get it to work.

When you do this you'll find that the encoder (dial) works backwards. To fix this you'll need to edit a file on the duet.

Open general.g and look for the following line
M918 P1 E4
and you'll change the E4 to E-4
M918 P1 E-4

Once you do that the encoder will work the way it is supposed to.
