I need to get a Hitachi X200 working off Modbus (I had it working OK under Mach3).
I followed the instructions here:
wiki.linuxcnc.org/cgi-bin/wiki.pl?VFD_Modbus
So far I just included the VFD lines into the .hal file. Now I get:
./7i92_spid.hal:301: execv(vfd.py): No such file or directory
./7i92_spid.hal:301: waitpid failed vfd.py vfd
./7i92_spid.hal:301: vfd.py exited without becoming ready
But I did put vfd.py into the path. Different items in the path. Added chmod +x to it. I did google this and saw mention that if you don't use execvp (with a "p"), it doesn't even search the path. Not sure if that's applicable but I don't know where that execv code is and don't plan to be trying to hack at it so randomly. What's up?
