I recently added a Creality BLTouch v3.1 to my Ender 3 which has a MKS Base v 1.6 motherboard and is running Marlin 2.0, but the Z-min never triggers.
I have made sure that the BLTouch unit lights up, uses the provided mount for the Ender 3 to get proper placement and is connected to the Z-min pins. Additionally, I have followed multiple youtube videos for connecting/setting the right parameters for the sensor. However, I haven't found the right combo.
I have tried both BLTouch and Creality BLTouch, different pin number assignments (other than the standard Z-min pin), but the status doesn't change with or without the sensor pushed in. Looking for suggestions on settings to apply, or if anyone has had this issue.
See pictures below:
- Connection to motherboard, tried using the other pin on the z min, and switching the black/white wires to see if they we're connecting wrong.
- BLTouch depressed which lights up as expected.
- BLTouch not illuminated when open.
