Re: EMC Have a Distance-to-go position DRO

Yes I agree that a program would be made to make the moves in CNC but
distance to go comes in very handy when proofing out a program and
making sure all work and tool length offsets are set right. When a
new tool is inserted into the spindle distance to go makes it very
easy to look after the G43H command has been given and see how for Z
has to travel to the top of the part which helps to prevent plunging
tools into the part or table.

The program can be run in simulation to make sure it is correct but
human error in setting work and tool offsets happens. Distance to go
is another tool to help check new programs when they are actually run
on the machine.

The only hobby level software that I have seen with distance to go is
Flashcut so far. Just wanted to find out if EMC had the capability.
