Creality V2 2 Board Diagram __link__ Page

Next time your Ender 3 V2 throws a MAXTEMP error or your BL-Touch fails to trigger, pull up the V2.2 schematic. Trace the signal path. Measure continuity. And remember: every 3D printing expert started by understanding just one board – often this humble, flawed, yet revolutionary V2.2.

The diagram shows a 0-ohm resistor (R100) near the driver that bridges the UART pin. If R100 is populated, you can enable #define TMC_DEBUG in Marlin. Part 4: Common Wiring Scenarios Using the V2.2 Diagram Scenario 1: Adding a BL-Touch (3+2 pin split cable) The Creality V2.2 diagram shows a specific 5-pin port labeled PROBE . However, many BL-Touch kits come with a 3-pin + 2-pin dupont cable. Connect as follows: Next time your Ender 3 V2 throws a
