Increase the maximum temperature setting in Marlin

I’m using SKR mini e3 v3 board and Marlin 2.1.x bugfix version. I want to increase the maximum temperature to 395. So I corrected lines 651 and 652 in the configuration.h file to 395, and the following error occurred, so I can’t build it.

Okay. So ask that at the Marlin forum, not here. The Marlin code has checks in place that you cannot exceed certain boundaries. We’re just the forum for the build system, not for Marlin configuration.

Oh I didn’t know that Thx
