A limit switch to conditionally disable z_hop from safe_z_home?
I have an Ender 3 with a BL Touch, so z_hop on safe_z_home seems to be a necessity. Unfortunately, this creates a condition in which if the Z axis is already at its maximum position when homing is prompted, it will crash upwards. Of course, this can be mitigated by reducing position_max by z_hop, but then you're losing out on build volume.
It seems to me that a good solution would be to have an end-stop switch that would interrupt z_hop when triggered, but I'm not sure how to implement that.
I've found this Reddit thread in which the OP seems to be dealing with a similar, if not identical situation, but it seems to have died without a working solution.
Is this just a new Klipper feature I should be requesting? And if so, how?
