Hi Jeff,
I'm currently using EMC 2.2.8.
As you said I'm using the parameter #5399 just to read the analog value. This
value sets the dimension of my workpiece. The tool path changes following the
new set value but the program keeps on displaying the same workpiece.
Is there any solution?
Since my workpiece is very easy (a parallelepiped) I tried also to insert in
Axis a cube but I need to retreive the right dimensions first. For this purpose
I tried to use python commands as you mentioned in the mail archivie:
import commands
....
float(commands.getoutput("halcmd getp motion.analog-in-00 "))
It doesn't work, but probably I don't use this code in the right point... Can
you suggest me where to create an object to be displayed?
Regards
Luigi
