BigTreeTech SKR V1.3 Full Graphics LCD Smoothieware Wiring

thingiverse

BigTreeTech SKR V1.3 is a 32-bit board that caught my eye as the perfect candidate for my 1-meter-tall delta printer, but right out of the box, I encountered a problem: the RepRapDiscount full graphics display only powered up and showed nothing. After successfully twisting the connector like in the MKS SBase setup, I realized that a similar approach could also work, albeit with a bit more complexity. Smoothieware uses SPI0 to communicate with the RepRapDiscount Graphic Smart Controller, but unfortunately, the SPI0 pin on my board was labeled as EXP2 instead of EXP1. To fix this issue, I had to swap the wires between EXP1 and EXP2. As with the MKS SBase setup, connecting an external SD card to the GLCD led to problems, so I opted not to connect it and instead stuck with the default microSD card that comes pre-installed on the board.
