Configure Marlin on Octopus Pro

I have a Bigtreetech Octopus Pro running a custom concrete 3D printer and I need Marlin up and running cleanly on it. The board is installed and powering up; the gap is the firmware. Your task is to build and supply a working Marlin setup, covering: • Complete, compile-ready Configuration.h and Configuration_adv.h adjusted to the Octopus Pro pinout and my printer’s mechanics • Correct driver mapping for TB6600 in UART mode (including any required jumpers settings) • Pin definitions and logic for a new limit switch on the X-axis endstop • Guidance (or script) to compile with PlatformIO and flash via USB so I can reproduce the process later The printer’s motion system and extrusion hardware are already tuned mechanically; I simply need the firmware side dialed in so I can start printing concrete reliably. If you need additional parameters—steps-per-mm, sensor types, or board revision—let me know and I’ll provide them straight away. Once the firmware boots with stable homing, driver communication, and limit-switch response, we’re done.
