multiple TLO settings

[Knowklew]

I have a 2007 Haas MiniMill and a 4th axis HA5C. I am trying to figure out how to use multiple TLO settings with the same tool at different parts of the program.

I normally use something like this:

T1 M6
G43 H1 Z1.0 M8

and the H1 corresponds to the TLO that I set in the offsets page. How would i set multiple offsets on the same tool? would it be as simple as going:

T1 M6
G43 H11 Z1.0 M8

and therefore have the H11 spot set to the different offset?

Thanks
Fred

Yes, but you will need to make sure you have H&T matching turned off.

Have you thought about using a work zero shift to control the variance? I have found playing with tool lengths in the program can be dicey, just my 2 cents

I agree, it's much easier and safer to use a work offset z shift to accomplish what you want. This will achieve the same result without having to turn off h and t agreement

EXCUSE THE SHOUTING BUT I WANT TO BE EMPHATIC DO NOT TURN OFF H & T AGREEMENT!!!!! THAT WAY LIES THE POTENTIAL FOR SERIOUS CRASHES.

Okay now I will calm down.

Easiest way is G51 Z(some value).

Set your tool offsets to a point somewhere above your highest work location then you adjust downwards by using G51 Z-nn.nnnn.

The reason i say "above your highest work location" is because then you have to use negative Z values. If you make an error and enter a positive value this means the tool stays way too high.

However if you set things up so that the Z shifts have to be positive...and make an error the tool goes way too low probably with disatrous consequences.
