Re: [Emc-users] Coffecup EDM

[dengvall]

I've not played with EDM for quite  a while.  > 10 years so I've 
forgotten most of what I knew.
I know of people that used hardware store lantern oil as EDM fluid. If 
it sounds like frying bacon
you are in the right range.
Sounds (npi)  like  fun. :-)

Re: [Emc-users] Any Interest or Ideas for a Linuxcnc Fest 2016 ?

[dengvall]

Hi Stuart,

Total change of subject here. Lcnc already had feed driven by a pin. I 
wonder if anyone has tried
monitoring the load on the spindle motor and adjusting for constant load 
not velocity. What I'm
thinking here is slowing down for corners to control chatter. If this 
really works then it should be useful for the usual hobby machine 
(wimpy) and for those trying to get better surface quality on production
machines. just a random thought.

 This date is nothing more than my attempt to set a goal to get everyone
 here and have a good time. The date is fluid on purpose.
