Limit switch problem

[Mikes Planes]

Hi All
We move to France this year and in the move my computer that contols my CNC was damaged.
I had most of the disc I needed, but I am having problem with the limits. My limits only work when they are touched and I back off. Before they would bounce what have I missed??

Regards

You need to explain a little more because if they stop the machine and then you back off they work again then they are doing what they should be doing.?

Sorry I may have miss led you . I can touch the limit switch but nothing happens, when I pull off the switch the machine stops. If I click on home X, Y, Z or home all I get a message Requested home axis home switch active please , can't read the rest of message. I am running Mach 3 scheen set 2010.

Try changing active low/active high setting in Mach and see what that does.

Limit backoff was set pos+ and shoud've been neg- ?. (or vice versa)?.
Effectively working backwards?.
