Hi Michael,

Sounds like a neat machine. I don't have  facebook account so I couldn't 
see the pics.

Have a look at emcrsh 
<http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Emcrsh>. This gives you 
full control over EMC over a network or local sockets connection. As 
long nothing untoward happens on the machine (such as hitting limits 
etc) then you should be able to simply send a series of commands and 
assume they are executed. A better solution would be to monitor the 
responses and act on any errors. it depends on how much time you want to 
invest.
