It's unfortunate that there isn't a way to approximate closed loop control with

I found the problem with the encoder. It helps to be switching the wire to

get any errors at shutdown, those would be useful to see. So would the

The source code to 'emcsvr' is ./src/emc/task/emcsvr.cc
Its function is to manage the lifetime of the nml shared memory segments

Hi
Having built a 1.5 m x 1.5 m CNC gantry router used for woodwork, I am still
amazed that it works
as well as it does, however I am now thinking that the axis should be moving a
little bit faster (
I recently costed a job that would have taken 15 hours to cut which seems a bit
excessive).
