Title: Coordinate Systems
Post by: black33guy on May 10, 2014, 08:33:24 PM
I have my mill running in all three axes.  I don't seem to be able to figure out even after watching the tutorials how to tell the mill where the bounds of the table are.  The video tutorial assumes a home switch.  I don't have one yet.  It seems like I should be able to teach the software where the table is and have some soft limits.  As it is, when I try to execute the roadrunner program, I eventually fault in the y-direction, mainly because I don't seem to be able to get the work-space positioned so that it's contained by the table.
Can someone give me a clue as to what I'm not understanding about this?  thanks, rex

Move your tool to the lower left of teh table then set XY to zero. That way you have the full extent of the table to work with.

OK, that worked.

Now I'm trying to set machine coordinates to 0,0,0 when I have the table positioned as such.  If I press "Ref All Home", then y and z set to 0.0 without moving the table.  x does not, the table begins moving in the x direction.  "zero y" and "zero z" have green boxes around them.  "zero x" has a red box.  The settings in the "motor home/soft limits" screen are the same for all three.  Why doesn't x behave the same as y and z?

Figured it out.  I had x configured with an input signal; turned it off and it works correctly now.
