Title: Tool positions and offsets help
Post by: krsykes23 on December 09, 2015, 04:50:05 PM
As I am quite new to this, I need help with setting up my machine.  As you can see from the attached image, I have an 8 position ATC
and a vac table.  I have set the Soft Limits to X Soft Max...525, Soft Min...0 and Y Soft Max...550, Soft Min...0.

This seems to give me the correct fixture offset that I need.  So my X0, Y0 is just about at the corner of the working envelope.

I have set my Fixture offsets to X190 and Y40 (Machine Cordinates X0, Y0), so that seems correct.

However, the bit that I'm puzzled with is the ATC tool positions.  For example, T1 has its center at X41 and Y88, from Machine Home
or X-190, Y-40.  How do I set the positions of the Tool Holders?  If I jog to T1 for instance, the DRO on my pendant says X41 Y88 but
if I enter X41, Y88 in the MDI, it moves relative to the working area, not the tool holder!!

I'm confused!!

Apologies...the text saying Machine Home should read X -190 Y -40 (not X -175)

Your fixture offset will be 0,0 in Work Coordinates and 190,40 in Machine cords.
Tools, Soft limits are relative to Machine 0,0.

To move in machine coords, MDI  G53 X,Y

Your directions look a bit unconventional, but that's another issue.
