Safe Z and Go to Zero enquiry

Simple one this but its stumped me.

When I press go to zero I want it to raise from the stock to safe Z height and traverses back across to Z and then go down. At the moment it does the opposite and skims across the stock (at Z0 I presume) until it reaches zero.

Can't for the life of me find the the Mach 3 checkbox to alter this and I'm pretty sure it was something as striaghtforward and checking or unchecking a box somewhere.

Any suggestions?

Config menu down to Safe_Z setup. Click allow Safe Z moves and set safe Z height.

Of course!! Brilliant, thanks mate

For safe_Z to work properly you really need home switches, well you don't need them but it's safer.
