This is marlin 1.1.9 configured for Tevo Michelangelo 3D printer in stock configuration.
NOTE: Fix for Tevo Michelangelo's low contrast LCD issue.
- Locate a u8glib library file \U8glib\src\clib\u8g_dev_uc1701_mini12864.c
- Find contrast field in the init sequence. Default value is 0x027.
- This is six bit variable. So it has 0x000 - 0x03F range. Looks like 0x030 produces good results.
