-# Snapmaker U1 Config
-This configuration has been extensively tested on my U1.
+# Snapmaker U1 — Klipper Configuration
 
-No problems have arisen. Tool changes have always worked reliably.
+> **Use at your own risk.** This configuration has been extensively tested on my U1 with no issues, but I accept no responsibility for any damage to your printer.
 
-However, this does not mean that problems cannot occur on other printers.
+This configuration optimizes the TMC2240 settings for the integrated XY stepper motors, enabling higher speeds and accelerations during tool changes.
 
-I therefore emphasize that use is at your own risk and I accept no responsibility for any damage!
+## Key Changes from Defaults
 
-This configuration optimizes the TMC settings for the integrated XY stepper motors and uses higher speeds and accelerations for tool changes.
+- **TMC2240 XY motors:** Custom chopper tuning (`TBL`, `TOFF`, `HEND`, `HSTRT`, `TPFD`, `VHIGHFS`, `VHIGHCHM`, `PWM_*`) for improved high-speed performance
+- **Max acceleration:** 25,000 mm/s²
+- **Max XY velocity:** 1,000 mm/s
+- **Tool change acceleration:** 25,000 mm/s²
+- **Tool change speed (fast):** 800 mm/s
+- **Sensorless homing:** TMC2240 (XY) and TMC2209 (Z) with reduced homing current
+- **Input shaper (MZV):** X = 54 Hz, Y = 47.5 Hz
 
-Requirements:
-1. The tool positions must be exactly correct.
-2. The belt tension must be correct.
-3. The printer calibration process must be completed.
-4. Tool changes must work without problems beforehand.
+## Requirements
 
-# My test setup:
+Before using this config, ensure:
 
-- Printer: U1 from Kickstarter campaign (without top cover)
-- Firmware: 1.0.0 + v1.0.0-paxx12-10 (extended)
-- Slicer: Snapmaker OrcaSlicer 2.1.5
+1. Tool dock positions are calibrated correctly
+2. Belt tension is correct
+3. Full printer calibration has been completed
+4. Tool changes work reliably with the stock configuration
+
+## Installation
+
+1. Back up your existing `printer.cfg`
+2. Copy `printer.cfg` to `/userdata/printer_data/config/printer.cfg` on your U1
+3. Restart Klipper
+4. Re-run bed mesh calibration (`BED_MESH_CALIBRATE`) — the placeholder mesh in this file must be replaced with data from your printer
+
+## Test Setup
+
+| Component | Version |
+|-----------|---------|
+| Printer   | U1 (Kickstarter, without top cover) |
+| Firmware  | v1.1.1-paxx12-13 (extended) |
+| Slicer    | Snapmaker OrcaSlicer 2.2.4 |
+
+## Notes
+
+- The TMC2240 driver temperature readout is unreliable. When active it may read ~20°C higher than the actual value.
+- The bed mesh in `SAVE_CONFIG` is a placeholder — replace it with your own calibration data.
+- `[include extended/klipper/*.cfg]` requires the extended Snapmaker Klipper firmware.
+- v1.1.1 requires **Snapmaker OrcaSlicer 2.2.4+** or Snapmaker App 2.2.3+.
+- v1.1.1 adds heated bed flatness deviation detection and new filament presets (PETG HF, TPU 95A HF).
