+Klipper Firmware — Deployment Guide (Manta M4P v2.0 / Ender 3 V3)
+
+Overview
+- Board: BTT Manta M4P v2.0
+- MCU: `STM32G0B1`
+- Bootloader offset: `8 KiB` (`0x08002000`)
+- Clock reference: `8 MHz crystal`
+- Communication: `USB on PA11/PA12`
+
+Pinout Summary (alias-based)
+- X: `MOTOR0_STEP`, `MOTOR0_DIR`, `MOTOR0_EN`, endstop `X_STOP`
+- Y: `MOTOR1_STEP`, `MOTOR1_DIR`, `MOTOR1_EN`, endstop `Y_STOP`
+- Z: `MOTOR2_STEP`, `MOTOR2_DIR`, `MOTOR2_EN`, endstop `Z_STOP`
+- E: `MOTOR3_STEP`, `MOTOR3_DIR`, `MOTOR3_EN`
+- Thermistors: `HOTEND_THERMISTOR`, `BED_THERMISTOR`
+- Heaters: `HOTEND_HEATER`, `BED_HEATER`
+- Fans: `PART_COOLING`, `HOTEND_FAN`
+- Probe: `PROBE_SIGNAL`, `PROBE_SERVO`
+
+Configuration Reference
+- Firmware settings are captured in `klipper/.config`:
+  - Architecture: STM32
+  - Processor: STM32G0B1
+  - Clock Reference: 8MHz crystal
+  - Communication: USB (PA11/PA12)
+  - Bootloader offset: 0x08002000
+- Printer config: `klipper/config/manta_m4p_v2_enderv3.cfg`
+  - Update `[mcu] serial:` with your device path from `/dev/serial/by-id/`.
+  - Calibrate `rotation_distance`, `run_current`, and sensor types for your hardware.
+
+Build (WSL/Ubuntu)
+1) Install dependencies:
+   - `sudo apt-get update && sudo apt-get install -y make gcc-arm-none-eabi python3 libncurses-dev`
+2) Build:
+   - `cd /mnt/c/Users/poopo/Documents/trae_projects/manta/klipper`
+   - Ensure `.config` exists (provided).
+   - `make olddefconfig && make`
+3) Output:
+   - Firmware: `out/klipper.bin`
+
+Windows Flashing (STM32CubeProgrammer)
+1) Enter DFU:
+   - Disconnect USB, hold `BOOT`, tap `RESET`, release `BOOT`, reconnect USB.
+2) Program:
+   - Start address: `0x08002000`.
+   - File: `out/klipper.bin`.
+   - Click Download; then press `RESET`.
+   - Optional CLI: use `klipper/scripts/flash_stm32_usb_dfu.ps1` (requires STM32CubeProgrammer CLI). It connects via `port=USB`, writes at `0x08002000`, verifies, then issues reboot.
+3) Alternative:
+   - If offset fails, rebuild Klipper with "No bootloader" and flash at `0x08000000`.
+
+Host Integration (Pi/PC)
+- Verify serial: `ls /dev/serial/by-id/` and copy the full path into `[mcu]`.
+- Restart Klipper service and connect.
+
+Testing Protocol
+- Axis: Test X/Y/Z jogs and homing; verify directions and endstops.
+- Temperature: Verify hotend/bed readings; PID tune as needed.
+- Probe: Deploy/retract and Z-trigger; perform `G28`/`BED_MESH_CALIBRATE`.
+- Safety: Test `EMERGENCY_STOP` and max-temp protections.
+- Communication: Send G-code, check logs for errors.
+
+Troubleshooting
+- USB not detected: try different cable/port, ensure power, re-enter DFU.
+- Driver issues: install STM32CubeProgrammer or use Zadig WinUSB for DFU.
+- Wrong offset: confirm `.config` bootloader and start address alignment.
+- Serial mismatch: always use `/dev/serial/by-id/...` not `/dev/tty*`.
+ - Verification: `out/klipper.bin.sha256` contains the SHA256 of the built firmware (generated via `certutil`). Use it to validate the binary before flashing and for post-flash integrity checks.
+
+Version Control
+- Do not overwrite critical files; track changes in `CHANGELOG.txt`.
+- Record builds in `Deployment_Log.txt`; log test outcomes in `Test_Results.txt`.
+
+Reproducibility Notes
+- With `.config` + `manta_m4p_v2_enderv3.cfg` + this README, another technician can rebuild and deploy identical firmware.
