G53 G0 Z0.

if you dont mind what postprocessor are you using and you may post the file here if you alredy modified one

Hello,

Perhaps I was wrong. For me, Z0 level is my ground machine level (so tool touch machinning plan) and after I touch the top of my part (before machinning).

Because if Z0 is under my part, LinuxCNC will not want to start machinning, because Z will be negative !

I understand and I would prefer that the tool be far from the part to machine before tool changing.

So where is my mistake ?

Machine Coordinates is where it homes to. Same all the time usually at the highest the z can travel without hitting limit switch.

G53 is machine coordinates.

When you touch off your part that will be work coordinates, or work offset.... G54, G55 etc....

When it gets G53 that means it is referencing 0 as machine 0 for whichever axis.

G53 (machine coordinates) G0 (machine rapids)

Hello,

So I can just remove G53 lines, but perhaps there is a better way to proceed ?

Could you give me a post or a link to the good way to take origins ?

I think I miss something

Thanks

can you show us your ini file
there is maybe somthing we can change
