Hal command help needed was created by Ivan_The_Red

Im trying to find a way to switch the display between machine coordinates and fixture coordinates.
Im trying to build a pendant and cannot find any HAL commands that correspond to these functions.
I'm using the "AXIS" interface, can anybody affer any insight ?

Thanks

The # key switches between Machine Coordinates and Relative Coordinates, if you can send that key stroke from your pendant that would work. AFAIK there is no HAL command to do that. I don't see anything in the python interface that would do that either... you might have to dig into Axis to see how it changes from machine to relative coordinates.

Hi

There aren't any commands to switch, you have to change what you are reading for the current position

Look at axis
www.linuxcnc.org/docs/devel/html/man/man9/axis.9.html

and halui
www.linuxcnc.org/docs/devel/html/gui/halui.html

for starters

If you want to look in Axis, start your search with vars.coord_type
