I plan on putting the VFD drive close to the motor and well away from my other linuxCNC controls. Hopefully this will hel

Re: [Emc-users] mesa 7i80 configuration

. So now I wonder if for your test you used the bit file downloaded from the mesa website in the 7i80 zip file or did you use a file from some other place? regards, John Figie ___ Emc-users mailing list Emc-users@lists.sourceforge.net
