@phaedrux No not really . I think it was just a lose joint / bad crimp. I did not get any driver errors nothing .

@lodger Seams i wrote this in a bit of a hurry and does not make much sences.....SORRY

Ok i have one of these :
https://wiki.fysetc.com/Generic_12864_Panel/

Its states its pin Compatable with the MINI 12864.

I can not seams to figure out how to get the backlight working.
This is not a RGB like the Mini and i have the Mini working fine so my config is correct for that.

I am only playing and its not inportant for me to get running . Just a bit of fun. Any Ideas

Here are some notes I made when I was looking at this:

EXP2 is the same on the Mini and the ST7920 display but reversed between them. EXP1 is also reversed but has the following additional changes The 3 Mini has LCD_A0 where the RRD display expects CS. This is handled in firmware - the firmware uses A0 as CS when a type 1 display is configured in M918. The Mini has LCD_RST (which the Mini just ties high through a pullup resistor) where the type 1 display expects SCLK The Mini has the CS pin where the type 1 display expects MOSI ENCA and ENCB are also swapped, but that doesn't matter, you can change the direction in the M918 command

So I think the easiest way to drive the display would be:

Reverse the connectors at one end of each cable Cut the conductors in the EXP1 ribbon cable that carry LCD_RST and SPI2_CS2 from the Mini to wrong pins on the display On the display add links to carry MOSI and SCK from the EXP2 connector to the correct pins on the EXP1 connector

I have not tested this.

Sorry for the late reply been busy....

I final got round to having a look . But when i powered up the printer she was reading the correct temps.
I dont know what i was doing wrong and i have not changed anything but she is working fine again..

So Big tnaks for every one help
