Re: [CAD_CAM_EDM_DRO] Re: Homebrew DROs

Paul,

First off, a disclaimer, I know absolutely NOTHING about Mac's and not much
more about C programing. However as C is supposed to be portable across
platforms, could you not modify the source code for the Lindsay/Eckstein
program to make it work for you?? Just a thought .

However haveing said that, also remember the program MUST be run in a boot
to DOS mode as windoze will not allow it to run accurately in a dos
window:-{( A while back, there was a thread about a possible real time
windoze, but that is another round-to-it project. Right now, am trying to
get the DRO setup on my lathe. That project got set back by the loss of the
hard drive controller and hard drive in the shop computer (an old 486 vesa
bus). So most of this week has been taken digging in the junk box to come
up with another computer to use on the dro.

Got it up and running last night and now to do some debugging to get the
entire system up and running. I have made additional hardware for the lathe
and am running the encoder outputs to an AB box. Running a little behind
schedule as I had hoped to have all done and the web site updated by the
end of last month.

Let me know if I can help.
