then second is there a way to hock up a signal to go to e stop if this happens for any other reason. ( I have yet to look into this)

This is how I did it for the similar (I think) AM882; http://www.mycncuk.com/threads/6565-...7622#post57622

Contacts of the K2 relay would go in series with your emergency stop buttons

just to add to thins the weight of the z axis is aprox 14kg and its on a 1605 screw and a 3nm nema 23. I ran it at 50% and it actually cut out sooner. I have got another set of pulleys coming which will give a 3.8:1 ratio so hoping that may help and in the mean time Im going to try taking of the spindle to reduce the weight and see what that does.
