The pain I feel inside when I klick home z in octoprint (remote from work) and realises that old cold plastic-oze on the nozzle is touching the bed before z probe! Then watching the printer break itself trying to hit the endstop! Why cant that damned M81 work (buffer I know!)
I keep telling the wife I’m going to move the printer to the other room, but man, I don’t trust it enough to kick things off from a distance.
Yep, one thing goes wrong and it might bite you (or itself) badly!
Why is it that hard to make a override stop funktion?
Consider using the home-up technique as detailed here:
Great for fire and forget, as plastic on the nozzle will never stop it from homing. It also means homing is always safe, even if parts are on the bed.
Sanjay thats a great feature but im running autobed leveling.
Perhaps try a spring mounted bed design, its forgiving of several mm of over-z
