I have a strange problem with the z-endstop,using mechanical switches.
When sending the m119 command.all switches show open except z min,which shows triggered.
When i press "home" in pronterface,the z axis goes UP just a fraction and stops,and will not go down.
If the endstop sw is pushed in by hand,z will go down until sw released,and go up 0.1,1,or10.
If i hold down the sw and keep it down until the z touches it,the z motor keeps going,and starts to rattle until i reset the printer.
I have tried reversing the connector on the ramps,inverting z in config,h in marlin,but nothing seems to work.
I've been right through this forum,and didn't find any reference to this particular problem.
I'm guessing it,s possibly a setting in marlin i don't know about.
