When installing or upgrading a board, the "paper test" is the standard method for manual bed leveling and setting Z-offset: Klipper documentation Home All Axes: Use the printer interface to command a home (G28). Slide Paper:
| Symptom | What the Diagram Reveals | Fix | |----------------------------------|----------------------------------------------------|------| | Heater not reaching temperature | Check TH0 thermistor pull-up resistor (R5, 4.7kΩ) | Replace R5 or thermistor | | Stepper motor grinding noise | MS1/MS2 jumpers missing or in wrong mode | Set jumpers for 16 microsteps | | BL-Touch deploys but doesn’t stop | PB7 is not reading because bed heater is active | Use Z_MIN_PROBE_PIN override | | USB not recognized | Fuse F2 (500mA) blown near USB port | Solder 0603 500mA PTC fuse | | Random thermal runaway | Poor solder joint on HEATER_BED MOSFET gate | Reflow Q2 with solder iron |
If you are moving to advanced firmware, keep these key points in mind: require careful configuration, Klipper is compatible but with driver limitations , and the Marlin pin mappings must be accurate to avoid MOSFET errors. Happy printing!
Dual-extrusion support capable (features hardware ports for E0 and E1 motor controls).
It is highly likely you are looking for the pinout diagram for the mainboard, which is the standard 32-bit board used in the Ender 3 V2, Ender 3 Pro, and Ender 5 Pro. Creality V2 2 Board Diagram
Having a detailed diagram is more than just a technical curiosity. Here's how you'll use it in the real world.
Creality V2.2 board (often referred to as the V2.2 or V2.2.1) is a 24V silent mainboard commonly used in older high-end models like the CR-10S Pro Go to product viewer dialog for this item. Go to product viewer dialog for this item. CR-10S Pro V2 Go to product viewer dialog for this item.
Tied to the same Z-axis driver channel. This allows true dual-Z stabilization without needing an external splitter cable. E-Motor: Drives the extruder filament feeder. 3. Endstops and Sensors (Top Left Edge)
Full-sized USB Type-B port, SD Card reader , and dual EXP display ports ( EXP1 and EXP2 ). Interactive Layout Breakdown When installing or upgrading a board, the "paper
You are not alone. The community has consistently noted the lack of official documentation for the Creality V2.2 (and V2.1) boards. Datasheets containing max voltages, current limits, and comprehensive pinouts have never been publicly released by Creality. The primary source of truth remains the Marlin and Klipper configuration files.

High-amperage output providing power to the heated print bed.
A dedicated 5-pin port is often present or can be wired via the breakout board for auto-leveling. Wiring Layout CR-10S Pro V2 specifically, the V2.2 board often connects to a breakout board Here's how you'll use it in the real world
The V2.2 board does not bring out the TMC2208’s UART pins. This means you cannot change driver current or enable stealthChop2 via software—a major downgrade for advanced users.

The , often referred to as the V2.2.1 "Silent" motherboard, is a legendary 8-bit upgrade originally designed for the Creality CR-10S series and later utilized in printers like the Ender 5 Plus. Unlike the newer 32-bit V4.2.2 boards found in the Ender 3 V2 , the V2.2 uses an Atmega 2560 processor and is prized for its reliability in dual-extrusion or dual-Z axis setups. Understanding the V2.2 Board Layout
Connect the Ground (usually Brown or Black), VCC 5V (Red), and Signal/PWM (Orange or Yellow) wires to the matching pins on the board’s extended sensor header.
