Hi All,

A newbie here. This past week I attempted to install a BL Touch to my Ender 3 Pro. The mainboard on my machine is V1, I downloaded the firmware RAR file but when opening there were errors flashe up such as: “Access violation at address 75EB1E60 in module ‘KERNELBASE.dll’. Read of address 02538000”. The same message flashes up several times but with different address numbers.

Consequently, when I try to select the correct chip there is nothing in the pull down menu.

What am I doing wrong?
