[sudo-discuss] help sudoroom have a CNC machine!

[Jake]

theres no need to dismantle anything, the accoustic probe just unplugs and 
you stick a dremel on there, easy.

i think it will be strong enough for routing.  ideally we will observe the 
encoder values while moving the head and notice when it is tool crashing 
somehow and protect it from mistakes.

the ultrasonic probe is very small, not very powerful im sure.
