I am using a HE161192 (Cocoon Create Touch - Australia) with a genuine BLTouch v3.1, a reseller supplied extension cable and ADVi3pp-BLTouch3-Mainboard-4.0.3.hex firmware.
For the most part it is working great, but I am getting “Ghost Touches?” when running the auto bed levelling process. The pin will deploy and then retract again before the Z axis moves, the Z then moves down and touches to plate and moves on, the result is that 1 of the 9 points will ready as being way higher that it actually is, this will happen roughly 1 in 30 touches, the result is I need to watch the level process and re-run if I get a false trigger.
I have checked all my wiring to ensure it wasn’t a loose connector, I have it hot glued on the mainboard end. Any suggestions on how I might be able to track down the issue?
