Is it possible to have Z "go to Z" first to prevent possible damage ?

Right now when I press go to Z, X and Y move to 0 first and stop then the Z goes to 0.

Thx,

Steve

Turn on and configure "Safe Z", under the Config menu.

Safe Z is a must for me. I use 2.5" on my router as a safe Z because I use toggle clamps. I use .1" on the mill. I also like it to go to safe Z when I hit the stop button. If you have to go back home, the Z is up and it also picks it up in case of a bind or a stall on the spindle. I don't see that anymore yet, but saw it often when I was using the stock X2 spindle motor.

Hi SScnc
You can do as ger21 has said or just have the first line of Gcode to be G0 Z1.0 or what ever number you want it to be to clear fixtures etc you do not need a X Y move as this saves a lot of machine movement your machine will then go to your programed part start point which is your part zero

The only time you need a X0 Y0 is if that is your part start point which you would put under the Z axes Gcode moves

Also put the same G0 Z move at the end of your program for the same reasion before any G0X---Y--- moves & this will save you any crashing in to things at the end of your program as well

The gotoZ button in Mach (which is what he was referring to) is hard coded, if you use it, you need to use SafeZ

Turn on and configure "Safe Z", under the Config menu.

That did it.

Also, I just started writing some G-code for some simple operations yesterday so that info helps allot too.

Thanks for the help guys.

Sheetcam has a safe Z setting in it as well. Not sure what cam if any you use. No need to set safe Z then, but I still do it. They call it safe for a reason.

If you want to be really brave, you can change the button function using Screen4 (Mach's screen designer) to execute g-code commands and do exactly what you want. Let me know if you want to know how to do it.
