Re: [Emc-users] EMC2 - Alternate g-code input path?

[Ray H. <re...@up...>]

Hi Shon

I'm suggesting an inelegant solution but tcl/tk could handle such a
thing.  The EMC has the provision for running single blocks of g-code in
its MDI mode.  Tcl/tk has the ability to open sockets in; read, write,
or rw mode.  You have to modify the code in either tkemc or mini but
that is not to difficult a task.

If this is essentially a black box control with no need to view or
interact with the machine from the control computer you could rip out
most of tkemc or mini and just use the startup routines and then fire up
the socket.  This assumes that the signals are one way and no
confirmation of the message is required as I've not found a good way for
EMC to report that it has completed a MDI block.  Perhaps others know
how to get access to that status variable.
