I cannot find a firmware that works with the 4.2.7 board that allows the temp to reach 300°C+  
I have tried Autobuilder for days and receive these Errors:

Marlin/src/lcd/e3v2/proui/dwin.cpp: In function ‘void drawPreheatHotendMenu()’:

Marlin/src/lcd/e3v2/proui/dwin.cpp:3444:17: error: ‘drawFilamentManMenu’ was not declared in this scope; did you mean ‘drawFilSetMenu’?

Can anyone help?

This is an unrelated bug and has recently been fixed in this commit:
