Jeff,
For some reason, I was unable to get Les Newell's tool change
script to run UNLESS I named it the default name - hal_manualtoolchange.
Per your suggestion, I tried naming Les's script to
hal_manualtoolchange_new,
and then changing the reference to it in the .ini file. But when I started
EMC2,
no window appeared. So I waited a minute, and tried starting EMC2 again.
This time I got a dialog box saying it was already running.
There is a reference to the name in the script itself:
h = hal.component("hal_manualtoolchange")
Do I need to change the name here too?
Also, in the .ini file, the name appears in four places:
loadusr -W hal_manualtoolchange
net tool-change iocontrol.0.tool-change => hal_manualtoolchange.change
net tool-changed iocontrol.0.tool-changed <=
hal_manualtoolchange.changed
net tool-number iocontrol.0.tool-prep-number =>
hal_manualtoolchange.number
net tool-prepare-loopback iocontrol.0.tool-prepare =>
iocontrol.0.tool-prepared
Should I change the name in all four places?
Thanks,
Tony
