Review on BIGTREETECH Upgraded Direct 🔧 Control Motherboard for Improved Performance by Kory Shelton

Combined with the BIGTREETECH TFT50 V3.0 Display in Tronxy X5SA Pro (CoreXY) to add the much needed Z-Axis Auto Alignment feature Wish I could use the original TFT display. Of course, the first thing I did was make sure I got the Rev B board before doing anything else. Seeing "HY1904" instead of the killer MOSFET was a relief, and of course there were two seals (silver and green) on the back of the board. Installation was tricky as the two stepper motors, nozzle heater, thermistor, filament run out sensor and X-stop sensor are routed through a central 36 pin cable to simplify wiring, but once you get a bit done , setting up the SKR 2 is pretty easy. EXCEPT as an upgrade/upgrade to SKR 1.4, the TFT connector has been completely changed from its predecessors, so all those helpful 1.4 YTube videos (which are currently missing on the SKR 2 board) mislead you, but the output on the Sites from github will point you in the right direction when you find out that the free connector on the BTT-TFT cable is the reset pin. They pack a lot of features into this small board, making some operations difficult for clumsy fingers. Sized to be upgradeable, the board is dwarfed by the large cavity available in the original Tronxy box. To keep the auto Z alignment I would definitely buy another BTT board, although next time it will probably be an Octopus or its successor to get four corner auto alignment.
