Hello;
I'm using Mach 2 but keep having tool offset problems when I have a program that uses multiple tools.
After I make the tool change (manually), then hit "start", the tool length offset is not added !!
Am totally confused
Just before the program request for a tool change, the g-code looks like this example;

G49 z2.0
m05
Goo x0.0 y0.0
m06 T02
M03
s3000
etc.......

I thought my problem was because my post processor was installing G49 before the tool change, but I think it has something to do with the way I have setup Mach.
I've been editing my g-code files manually by removing the "G49" command, before machining, but I don't think this is the proper fix.
Any help would be greatly appreciated.

G49 is generally used to CANCEL tool length compensation of the tool in spindle before toolchange and then after toolchange you're supposed to put in G43 H2 (if tool no=2) together with the first Z-axis move after toolchange. For example:

T4 M06
G0 X0 Y0 S800 M03
G43 H4 Z10. (G43 activates length compensation)

hope this can help you,

G43 Hmmm !!
Maybe it's a post processor issue then !! I'm running Dolphin Cad and will post this question there.
Thanks
