### Basic Information: Printer Model: Ender 5 plus MCU / Printerboard: BTT Manta M8P `klippy.log` ### Describe your issue: Is anyone using BTT Manta M8P with BTT mini 12864 display? I have the following setup in my printer config (MKS mini 12864 LCD) but my mini 12864 doesn’t come life. I have tried rotating the EXP1 and EXP2 connectors -still no life. Is the mini 12864 even compatible with the M8P? Everything else is working fine using Mainsail.

Thanks George I will give this a try. ---

It ended up working however, the backlighting is not on and I don’t get the “lights” menu option as shown on the BTT instructions to turn it on: ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/e/e72a871877ae0c0f480e1112c3b03af6761ef225.jpeg) Maybe I need to flash new firmware on the display?? ---

The display doesn’t have firmware, and those screenshots don’t appear to be Klipper. That’s probably Marlin. ---

Had it working on my SKR2, maybe I find the files in my backup folder. ---

I had to add the following sections in my config to get the backlighting to come on but there doesn’t seem to be a way to control the colour from the display menu or knob.

My mini 12864 has an SD card slot. Any idea what this would be used for? Can klipper access this (to load G-code files or backup files)? ---

No, Klipper can only access files on the host system. That slot can be used by Marlin. ---

OK Thanks for your insight
