What you’ll get: a practical overview of hardware options, how to flash Klipper, run resonance tuning, set input_shaper, calibrate pressure_advance, and pick safe speed/accel profiles.

Prerequisites

• A compatible printer (Cartesian/CoreXY preferred), stable mechanics (tight belts, square frame)
• One of: Raspberry Pi (or equivalent SBC), an integrated Klipper controller, or a vendor tablet (e.g., Sonic Pad)
• Basic network access (Wi-Fi/Ethernet) and a microSD card for firmware

Choose Your Path

1. DIY SBC + Mainsail/Fluidd: Most flexible. Install the MainsailOS or FluiddPi image, then compile and flash Klipper to your printer’s mainboard.
2. Vendor Klipper Tablets: Faster setup (e.g., Creality Sonic Pad). Follow the vendor wizard to flash and import a config.
3. Printers with Klipper-like features built-in: Some 2024–2025 models ship with input shaping; you can still refine tuning.

Install & Flash (high level)

1. Write MainsailOS/FluiddPi to the SD card; boot the SBC; connect to its web UI.
2. In the UI, open the Klipper firmware builder; select your MCU (e.g., STM32F103, RP2040), clock, and bootloader.
3. Flash the resulting klipper.bin to your printer board (via SD or DFU), then reboot.
4. Upload a matching printer.cfg (start with a community template for your model) and edit kinematics, steps/mm, endstops, thermistors, and bed size.

Resonance Tuning (Input Shaping)

Goal: find your printer’s vibration frequencies and set an input shaper to cancel ringing/ghosting.

With an accelerometer (best)

1. Mount a supported accel sensor to the toolhead (ADXL345 is common).
2. Wire to the MCU/SBC (SPI), enable the adxl345 section in printer.cfg.
3. Run the built-in test from the web UI (X and Y axes). Download the graphs.
4. Set [input_shaper] with the recommended shaper (e.g., mzv, zvdd, eiq) and frequencies.

No accelerometer (good enough)

1. Print a ringing test at moderate speeds/accels.
2. Try the built-in auto-tune (if available) or manually increase shaper freq and type until ringing reduces.

; example snippet (values differ by printer)
[input_shaper]
shaper_type_x = mzv
shaper_freq_x = 52.0
shaper_type_y = eiq
shaper_freq_y = 40.0

Pressure Advance (Linear Advance equivalent)

Compensates for extrusion lag during speed changes for sharper corners and consistent walls.

1. Print a PA calibration line/tower from your UI macros.
2. Pick the value where corner bulging disappears and lines look uniform.

[extruder]
pressure_advance = 0.045  ; typical range: 0.02–0.12 (varies by hotend/extruder/filament)

Safe Speed & Acceleration Targets

• Starting point (quality): 60–90 mm/s, accel 3000–5000 mm/s²
• Balanced (most parts): 120–180 mm/s, accel 6000–10,000 mm/s²
• Speed runs (tuned CoreXY): 200–300+ mm/s, accel 10,000–20,000+ mm/s²

Tips: Increase speed after you’ve nailed input shaper and pressure advance; check hotend flow limits, bed adhesion, and cooling.

Don’t Ignore Mechanics

• Set correct belt tension; replace worn idlers
• Square the gantry; lube rails/rollers appropriately
• Verify stepper current (TMC drivers) and keep motors within temperature limits

Common Pitfalls

• Over-shaping: Too aggressive can soften detail—dial back freq/type
• Under-extrusion at speed: Hotend can’t melt fast enough—raise temp, larger nozzle, or lower flow
• Layer shifts: Belt slop or stepper current too low

Wrap-Up

With Klipper, input shaping, and pressure advance, you’ll print faster and cleaner. Tune once, then enjoy reliable speed with fewer ripples and sharper corners.
