Positive TLO's

[Jim Whipple]

I need to drill a 1/8 dia hole 3.812 deep. Not a problem except my tool offset is positive. The tool is above where the tool change location is. When I post the program, Mcam does the G54 x and y moves prior to picking up a G43 to read the TLO....Being relatively new to MC, I was wondering what I'm not seeing here, or do I just need to manually edit the program to call the length offest earlier??

Thanks for the help

I often put parts into my machine which are too large for the machine to accept at the tool change height.

What you are doing sounds to me like a crash waiting to happen. If the spindle has the ability to move to a point higher than Z0, ie positive tool length, why don't you just move the axis zero to the same point as the Z+ axis limit.

Another word of advice. Don't use an M6 toolchange. Manually change tools, and just call the tool length without the M6

That's was funny

Sometimes I add an extra drilled hole in a --safer-- x,y location, at the correct hight, then light edit it after posting.

For me this just makes it easier to see, as well as recording the work that is out of the envelope.

I was just wondering if there was a way to use the clearance function on the parameters page to effectively do the same thing

Sorry for the long post
