Question about tool offsets
« on: November 18, 2014, 06:52:27 AM »
I have two tools, number 1 and number two.  Number two tool is .100 longer than tool 1.  When I set up Mach 3, I set tool 1 as tool 0 and zero it.  Then I set tool 2 offset.  The saved offset page shows that tool 2 is indeed .100 longer.  In Mach 3, when I switch from tool 1 to tool 2, I see the tool length offset in the window, so I know that Mach is registering.

Here is the puzzle.  When I press go to zero , tool 2 falls short by .040.  This phenomenon occurs only I first set up and calibrate the offsets.  Once I manually zero tool 2, it stay at the "new zero".

If this were a machine issue, I'd have issues with the material not cutting evenly. But, as I said, this happens only during calibration when I first set up the tools. Once I've corrected the offset manually, the tool keeps cuts to the correct depth.

I've measured the tool length and they are correct.

Am I missing something?

Not sure why you are setting tool1 as tool 0.
Try calling tool1 and G43H1 and then zero then call tool 2 with G43H2 and see.
