I have an new Ender 3 Max with Creality original BL Touch that I just bought. Works perfectly with stock firmware. I get a blank screen on the Ender-3 Max V2_Marlin 2.0.8_JyersUI 1.3.4_4.2.2_BLtouch HS prebuilt binary downloaded on this site. With power off I insert the 8GB SD Chip formatted as FAT32 and 4096 per sector. The only file on the newly formatted card is the aforementioned. I also unplug the cable to the old display and plug in into the DWIN display that runs perfectly on an Ender 3 V2. I verified that I have the 4.2.2 board.

Always just the black screen even after waiting 5 minutes to boot. Nothing. I can see power is going to the DWIN screen as the is a small amount of light on the display (very dim grey... no words or figures appear). I power down, remove the SD card, power up and the system is frozen. Just a black screen. The BL touch in all cases does give 2 red lights so I know that at least it works.

I can go back to the stock firmware from Creality and the old screen and everything works again. I used the same SD card to isolate that as being the problem. I also verified on an Ender 3 V2 that the DWIN screen did not get damaged.

Hi I install the screen of v2 into a ender max, but for some reason when I use UBL compensation is not working, I tried with g29 A and M420 S1 in my initial code but it doesn't works, when I inspect manually the mesh is ok, but for some reason when I send something to print, doesn't work.
