Go Home
« on: November 08, 2010, 10:45:13 AM »
Hi
Small problem, while ive been setting up my new machine i have had to hit STOP a few (hundred) times.

Thats fine works fine, but then when i hit GO HOME Mach moves in the x or y direction first gets to home position then moves up z

It does go home, but i want it to move up z before it moves x or y.

is this a Gcode problem or does Mach control the Go Home function.

Anthony.

Set up a safe Z and it should move first, you will find it from Config  menu.

How do you set up a safe Z to get it to move first?

Config Menu then Safe Z setup, you will see a box like the pic. I personally prefer using machine coords for safe Z as it is always a fixed point where as the others are not.

Awesome, thanks. Since you have been nice enough to bail me out of previous fixes, I thought I might ask for more advice. I'm trying to set soft limits but I can't seem to get it right. The actual limits of the machine are X=47.5", Y=18", and Z=6" but when I put these numbers in motor home/soft limits screen, I get "soft limits max<min" errors in the status screen. And I'm not sure what the other settings should be, such as reversed and home neg. I have the setting currently at X=Max 47.50/Min 0, Y=Max 18.00/Min 0, and Z=Max 0, Min 6, with Reversed and Home Neg all in red. I still get errors. Can you guide me through this?

Z Min should be a negative value so try with -6

Try a minus value for the Z axis since it goes from positive value(top) to a negative value.

No need to be sorry Jeff, often happens that two people type at the same time :)
