BIGTREETECH GTR V1.0 motherboard is a high-performance 3D printer main control board with the core controller STM32F407IGT6, which was launched by the 3D printing team of ShenZhen BigTree Technology CO.,LTD ., aiming at solving some problems existing in the motherboard market. The BIGTREETECH GTR V1.0 is the motherboard, and the BIGTREETECH M5 V1.0 is the expansion board.
This is part of the GTR board schematic (M5 extension board connector)
This is part of the marlin pin configuration file for the GTR board
M106 command with P3-P7 parameter controls fan1-fan5 on the M5 board correctly. Though marlin config says that M106 P7 uses PE14 pin schematic says that this fan (FAN E7) uses pin PI5.
And this is not the only difference - there are more of them. Are they schematic misprints/errors or I missed something :)?
