Folks -
Okay - I just KNOW I'm doing something dumb.... Lately I've been having trouble establishing zero Z. This means that either all my cuts perform flawlessly, inches above the material, or SB technology does its level best to jam the router all the way to the collet through the table.
I've been doing everything in PW1 - setting Z for the machine bed and going on my merry way. The cuts look like they occur properly in 3d, stepped cuts, etc... I've ran the 0Z routine in SB, at machine bed height and that worked fine. Now I also have set 0Z from the top of the material - I suspect that this is where I'm getting in trouble.
If I set 0Z on the machine at the top of the mat'l and have 0Z in PW set at the machine bed, that would have the actual position of the cutter tip too deep by the thickness of the material. This could account for the BIG noise the router made and the stains in my underoos when this somehow occured.
It seems like OZ should alwys be the machine bed, but I've discovered a blind spot that keeps screwing me up. As a newbie to 'Bots and PW, it seems like there are too many places where the same information is used, and that mislocations of reference points is a vulnerable area. But at least I didn't crash a probe into what was it, Mars, because I didn't convert meters to feet... Where and when would you specify the different locations of 0Z, and for that matter, the corner or center of the workpiece as XY0Z.
I'd appreciate any sage wisdom for an easier method of operation for preserving my router and my shorts.
