Limit switches, inertia and controllers

[routercnc]

On this general subject there are at least 4 ‘end of axis’ type features:
Home (physical sensor to home and zero the axis)
Soft limits (software detection for end of travel)
Limits (physical sensor for end of travel and invoke stop or estop depending on your setup)
Buffer (mechanical buffer for physical hardstop- not often seen on DIY machines but VMCs often have a rubber stop on the ballscrew as a last resort as these machines are heavy and move fast!)

I mention this as the other day I was jogging my machine around and managed to almost hit the home switch ( proximity type). I don’t have soft limits on and the home switch also feeds into my end of travel pin and does not invoke an estop (by design). I haven’t had a chance to investigate further but it looked like when I approached the home at full jog speed it treated it like I had released the jog key and decelerated to a gentle stop. But because it was moving quickly, unlike during homing, it used up all of the 4mm travel. If this is the case I will have to tune the accel / decel to be quicker or set up soft limits. My sensors are head on as I couldn’t get them side on. Anyone else seen this or do you estop if the end of travel is detected?
