Hi Schooner:
Thanks for your quick reply. I think I known where was going wrong! I
checked the machinekit.ini file as you told me. this file was empty. That's
why rtapi needs UUID. I guess there was some thing wrong when I was
compiling machinekit source code. So I recompiled it. And this time I got
machineit.ini file. Now every thing works fine!
Thank you for your detailed guide!
