Attached is a image of the end plug of my CRTouch which goes into the motherboard.
When plugged into the motherboard G V IN G OUT pins, the wire colors meet each pin in the following pattern:
G = WHITE
V = BLACK
IN = YELLOW
G = BLUE
OUT = RED
The same pattern was true when they were plugged into the old motherboard I was using, and both of my 4.2.2 boards have a dedicated probe plug (built in). Judging by the BLTouch FAQ I am assuming that this is what each of the 5 wires are doing:
G = WHITE (Signal)
V = BLACK (Ground)
IN = YELLOW (Signal)
G = BLUE (Ground?)
OUT = RED (5v)
When using Crealty’s official firmware - the CRTouch probe would deploy just fine. However when using your Marlin firmware build, it does not deploy and it continues to flash red.
@CRCinAU is your firmware configured for this type of setup? If I need to switch around my CRTouch wires, what order should the colors be relative to the G V IN G OUT pins?
Here is a video of the CRTouch probe not deploying and flashing red. The Z-Axis does not react to the operation either. It is plugged in correctly as describe by my previous post. All hardware is new.
I’m using the latest build (now with the MarlinUI).
