Fixture Offsets - What Am I Missing?   Message List

Re: Fixture Offsets - What Am I Missing?

Tom,

I've always found the most convenient way to set fixture offsets is to use the
same methods used for setting G92 - position the machine using probing/edge
finding/etc. to part zero (or some other reference position), then set the DROs.
Or, if there is a known offset between fixtures, locate to one fixture zero,
then change fixtures and enter the proper new values into the DROs. Your way
works, just more typing.

"The "Zero" on the KMotionCNC affects the G90 global offset" - Do you mean G92?
G90 sets absolute distance mode.

Regards,
Ray L.

idea of fixtures such that there is a fixed known distance between them so you
don't need to zero each one separately?

the DROs would change, to reflect the different offsets set for the different
fixtures. I can't get that behavior at all with KMotionCNC. G54-G59 seem to have
no effect whatsoever that I can see. The DROs NEVER change when I execute a
G54-49, no matter what I've done to the DROs.

KMotionCNC, then set the DROS to X=1.0, Y=2.0, Z=3.0, A=4.0, then MDI "G55", I
expect to see the DROs go back to all zeroes. But, instead they don't change at
all. Why does changing fixtures with G54-G59 appear to have no effect?
