Rob, I am not familiar with Haas machines, though its my understanding that the controls are Fanuc "compatible" (please correct me if I'm wrong.) I know that with a Fanuc control equipped with Macro B, you can write a Fanuc macro which would be called in place of the standard M06 tool change command. Said Macro could check the machine position and move to a "safe" tool change position before executing the M06 command. This Macro would be assigned within the Fanuc parameter settings to replace the standard tool change command. The downside is that this macro will be active all the time unless you physically change the parameter back to its original setting.
I bring this up because if your Hass control has the same capability, you may be able to write something similar to address your problem.

The tool change level is about 4" lower than the highest point of the spindle travel. The G91 G28 Z0 line takes the spindle to tool change level, and sometimes this isn't high enough to clear the fixture. My question is this: Does anyone know another code, or some other way to have the spindle go all the way up? I am currently adding lines at the machine like: G00 G90 G54 Z8.0 (depending on where part Z zero is) to take the spindle as high as possible, but this changes with each program and setup.
