General Mach Discussion / Edge Finder Dia offsets wrong direction and Sherline Y axis measurements
« on: May 17, 2007, 11:45:09 AM »
I apologize, but I have misconfigured my Mach3 and searches through the forums, etc are not helping.
On my Y axis, once I enter the Edge Finder Dia, move my tool to the side of the work, and select the edge, the offset from the tool is applied in the wrong direction. My 0 gets moved farther away from the work.
My first thought was that I was selecting the wrong edge in the offsets screen, but both edges apply the offset in the same wrong direction, or am I becomming senile? To fix this, I have been entering G01 Y1.25 and zero Y again. It hasn't caused a problem except for annoyance.
A final question: I am new to CNC milling but I would have expected the scale on my Y axis of the sherline mill to match Mach 3 machine coordinates for Y. Instead, it is reversed. As the end mill moves in the +Y direction (which as I look at the mill means the end mill is moving away from me) for Mach3, my Sherline mill scale moves in the -Y direction. It is only an annoyance, but it means that I have to home my Y axis at 7" instead of 0". Am I completely reversed somewhere? Am I looking at my milling machine sideways or something? I can't imagine I am doing this correctly.
My X axis is working as expected for both edge finder dia and the movement of the endmill in the X direction matching the scale on the X axis.
Thoughts? And thank you,
Fowler
