so I have has my ender 3 for a month and having fun with the octoprint and metal hot end dry box herome set up. I purchased a ski mini e3 v2.0 was very quiet but I wanted a BLTouch. added the touch and could not get the board to work would probe 2 times and stop the print? I then after trying all I could think of ordered a reality silent 4.2.7 board and a different touch that I could plug into the "z" end stop. then downloaded the firmware from reality.com/download. for touch without board changed til from .rar to .bin and loaded onto SD card solid blue screen. I then used a different SD card 8 gb formatted to fat 32 blue screen. alonther SD card 128gb formate fat 16.blue screen. I got the firmware from teaching tech for the 4.2.7 board and BLTouch payed him PayPal and loaded his firmware same blue screen. I then changed the way I plugged in the bl touch using the 27 board on the 4.2.7 reality board same thing blue screen. I am about to return the creality board and bl touch to try another 4.2.7 board but I have read some people have had this blue screen problem and they fix it with the correct firmware but I think I have worn out my SD cards trying new firmware.lol

please help thanks!
