Need help wiring a CR Touch on my SV02

Sovol SV02
1

I purchased a CR Touch from the Solvol site, problem is I’m having issues with the wiring to my board. Can anyone explain the pin outs?

All the YouTube videos I’ve watched have the wiring wrong. This has it right. Note the first wire and second wire swap places. Don’t go by color, every manufacturer uses different colors.

Sure! The CR Touch wiring can be a bit confusing depending on your mainboard model. Typically, the CR Touch uses a 5-pin connector that includes:

  • Black – GND

  • White – VCC (usually 5V)

  • Yellow – Signal (Z probe input)

  • Red & Blue – for servo control (used for deploying and retracting the probe)

If your board doesn’t have a dedicated BLTouch/CR Touch port, you may need to connect directly to the Z-endstop and a spare servo port (often labeled as Servo, IO, or PWM). Always check your board’s schematic before wiring—it saves a lot of frustration.

Also, if you’re doing any firmware tweaks or trying to understand signal behavior and voltage levels (especially for custom setups), https://overchat.ai/math/math-ai is surprisingly helpful. It can solve circuit equations, analyze signal functions, and even assist with the calculus behind servo control timing—might be a good backup brain for your 3D printer projects!
