Decreasing Z Offset Measured by the BLTouch in a Sequence
I am checking the BLTouch z-offset, one thing I found that the z-offset kept decreasing when did it repeatedly as I shifted the bed down first then check z-offset ('G30 S-1' in RRF), the decrement amount is around 0.181mm per 500mm Z movement. This was observed stably, as 50mm has decrement 0.02mm, etc.
So I think the BLTouch is fine here, but there are some other issues?
