General Mach Discussion / How to use Z soft limit with the Tool Length offset?
« on: February 23, 2017, 01:57:48 AM »
Hi Mach3gicians,
Mach3 Newbie here, i am doing my initial mill setup and i cannot figure what is the correct way to setup the Z soft limit (other axis are easy).
I want to use the Z soft limit to avoid my end mill to crash with the table. My tools have a big range of length.
The Z soft limit is in machine coordinate, but for a reason i don't understand (explanation welcome) the soft limit in Z do not add the "tool length offset" before evaluating the trigger condition.
As a result, Z soft limit need to be manually updated after each tool change. Otherwise
if my current tool is shorter that my "reference tool" the soft limit will trigger with the endmill very far from the table.
if my current tool if longer, the soft limit will do nothing and i will get a big hole in my table.
In all case, it really feel awkward...
Do anybody know a way to add some "tool length" awareness to the soft limit?
Thank a lot in advance
